  • Combining repeat and repeat-complex-command

    In Emacs, you can use C-x z to repeat the last command you input, and subsequently you can keep tapping the ‘z’ key to execute that command again and again. If the command took minibuffer input, however, you’ll be asked for that input again. For example, suppose you type M-z : to delete through the next colon character. If you want to keep going and delete through the next few colons, you would need to use C-x z : z : z : etc. which is pretty inconvenient. So there’s also C-x ESC ESC RET or C-x M-: RET, which will repeat the last command which took minibuffer input, as if you’d given it the same minibuffer input. So you could use M-z : C-x M-: RET C-x M-: RET etc., but then you might as well just keep typing M-z : over and over. It’s also quite inconvenient to have to remember whether you need to use C-x z or C-x M-: RET.

  • Zip and Unzip Commands in Linux – Linux Hint

    Zip is a popular cross-platform command used for compressing and archiving data. Compression saves space by shrinking the size of data while archiving makes the transfer of data easier by combining multiple files or directories into a single file. Consider, if we have to transfer 5 files over the internet, each with size 50 megabytes; transferring all the files one by one could take a long time. Compressing the files to reduce the size up to 25MB, and then archiving all of them in a single file will make it much quicker to transfer the files than when they are uncompressed. Zip is the most widely used utility for archiving and compressing files, while the unzip is used for extracting and decompressing the zipped files.

    In this article, we will look at the zip and unzip commands in Linux, along with their command-line options and examples.

  • Linux Host File: How to Edit and Use it? | FOSS Linux

    To understand what a Linux host file is, we will need to undertake this tutorial through a visual aid approach. So fire up your Ubuntu terminal but first ensure you are a root user or have root user privileges.

    [...]

    You would get a ‘permission denied’ error as displayed if the Linux OS has sudoer privileges. This authentication aspect of the Linux operating system is important for the prevention of unwarranted security breaches. Since this tutorial article focuses on understanding the Linux host file, such authentication levels are important.

    The Linux operating system ensures that access to such file systems is privileged or authenticated. They serve an important role in the functional and design hierarchy of the Linux operating system. To test this theory, let us now update our Ubuntu Linux system using the ‘sudo’ command as a prefix.

  • Getting the most out of your Intel integrated GPU on Linux

    About a year ago ago, I got a new laptop: a late 2019 Razer Blade Stealth 13. It sports an Intel i7-1065G7 with the best Intel's Ice Lake graphics along with an NVIDIA GeForce GTX 1650. Apart from needing an ACPI lid quirk and the power management issues described here, it’s been a great laptop so far and the Linux experience has been very smooth.

    Unfortunately, the out-of-the-box integrated graphics performance of my new laptop was less than stellar. My first task with the new laptop was to debug a rendering issue in the Linux port of Shadow of the Tomb Raider which turned out to be a bug in the game. In the process, I discovered that the performance of the game’s built-in benchmark was almost half of Windows. We’ve had some performance issues with Mesa from time to time on some games but half seemed a bit extreme. Looking at system-level performance data with gputop revealed that GPU clock rate was unable to get above about 60-70% of the maximum in spite of the GPU being busy the whole time. Why? The GPU wasn’t able to get enough power. Once I sorted out my power management problems, the benchmark went from about 50-60% the speed of Windows to more like 104% the speed of windows (yes, that’s more than 100%).

    This blog post is intended to serve as a bit of a guide to understanding memory throughput and power management issues and configuring your system properly to get the most out of your Intel integrated GPU. Not everything in this post will affect all laptops so you may have to do some experimentation with your system to see what does and does not matter. I also make no claim that this post is in any way complete; there are almost certainly other configuration issues of which I'm not aware or which I've forgotten.

  • Zsh Vi Mode and Command History :: rm-rf.ca

  • How to Schedule a Crontab Job for Every Hour – Linux Hint

    Most Linux users are familiar with the Crontab job scheduler, which acts as a silent daemon that performs all the tasks assigned to it automatically, without any human intervention. This job scheduler makes the life of a Linux user much easier, as the user can hand over all the frequently occurring tasks to the Crontab scheduler so that these tasks can be executed automatically according to a specified schedule.
    At times, you may wish to execute a specific task once every hour. This could be an extremely challenging task for a user if the task were to be performed manually, as the user would have to be available every hour to execute that task. If the task is extremely critical and somehow the user misses the time to execute it, this could lead to severe consequences.

    The Crontab job scheduler can be a blessing in such situations. With Crontab, you can add tasks to the Crontab file to be executed as a job at specified times. This article will show you how to schedule a Crontab job to occur once every hour in Linux Mint 20.

  • In Linux, How to Find the Size of Directory and Subdirectories? – Linux Hint

    Before installing any new program on your computer system, the first thing that every user needs to ensure is that the system has a sufficient amount of storage space to hold that program and run it without any performance issues. Similarly, whenever you intend to copy or download files in any of the directories of your computer system, you need to check if that directory has an adequate amount of storage space available or not.

    There are multiple ways in which you can check the sizes of the directories and subdirectories within any operating system that is both GUI based and CLI based. However, since the Linux operating system mostly operates with CLI, therefore, its users are generally interested in looking for terminal-based methods of performing any task. Therefore, in today’s article, we will be talking about the methods of finding the sizes of directory and subdirectories in Linux Mint 20.

  • How to Configure the Crontab MAILTO Parameter to Send Notification to a Specified Location? – Linux Hint

    Whenever a Crontab job is executed, an email regarding the execution of that job is sent to the email address of the root user i.e. the email ID that you have provided while configuring your Cron daemon. These are the default settings of the Crontab service. However, in some situations, the users prefer to send these notifications to a location other than the root user’s email ID.

    You can consider a scenario in which a team lead has asked a subordinate to perform a job after every 4 hours. Whenever that subordinate performs that task, the team lead is supposed to report to the CEO about it, however, this will only be possible if the subordinate informs the team lead after every 4 hours that he has performed the assigned job. It means that if the subordinate forgets to do so, then the team lead will have to face the consequences.

    This task can be simplified if somehow the team lead automatically gets to know every time the subordinate performs that task without needing the subordinate to explicitly inform the team lead. Fortunately, the Crontab service in Linux allows us to do so by configuring its MAILTO parameter in such a way that it can send notifications to the desired recipient. So, today we will be talking about the method of configuring the Crontab MAILTO parameter to send notifications to a specified location other than the root user’s email ID in Linux Mint 20.

  • How Do I Check if Crontab is Working? – Linux Hint

    The crontab is an extremely useful job scheduler in Linux based systems that allow you to transform your daily routine tasks into crontab jobs that can run automatically at the specified schedule. However, since this job scheduler works silently in the background, that is why most of the users wonder whether it is working or not.
    At times, you assign the tasks of backing up your system or updating it to the crontab job scheduler. These tasks are considered very crucial for the normal working of any computer system. That is why, if they get missed out for any reason, your system will stop working consequently. So, it is considered extremely important to keep a check on your crontab job scheduler as well to stay informed about whether it is running or not and performing the jobs assigned to it or not.

  • How to Print the User Names of Users Currently Logged into the Linux System? – Linux Hint

    As a computer user, we completely realize that multiple users can use a single machine as per their requirements. These users generally create separate user accounts to which they logged in whenever they want to access that computer system. In any operating system, whenever an issue arises during the execution of any process, the most important concept is accountability which can only be achieved if you can attribute an action to the actual doer. It means that if an error has occurred just now, then there is a very high chance that the user who is currently using the computer system has somehow caused this issue to occur. Also, if a system administrator wishes to make any changes to the configuration files within the system, then before doing that, he needs to make sure that no user is currently logged into the system so that he cannot cause any hindrance in the system configuration.

    All these scenarios point to one common goal and that is to look out for how you can find out the currently logged in users of a system. So, in today’s article, we will be explaining to you all the different methods of printing the user names of the users currently logged into the Linux system on the terminal.

  • How to install Softmaker FreeOffice on Ubuntu 20.04 or 18.04 LTS - Linux Shout

    FreeOffice doesn’t offer all applications as we have in MS-office, instead, it focuses on three main day to day usage office apps. They are Text (an alternative to MS Word), Presentation (like PowerPoint), and PlanMaker (SpreadSheet).

    With the help of this free office suite, we cannot only open native file formats of Microsoft office such as DOCX, XLSX, and PPTX, even saving of files into them is possible as well.

    Those who are already familiar with the interface of Microsoft office would not feel a problem in getting used to FreeOffice because of its MS-office like ribbon menu panel. However, a classic one is also available if some of us would like to use that.

  • How to move Request Tracker into a Linux container | Enable Sysadmin

    Even though it took me a long time to get motivated, I finally containerized several personal Linux services. I've documented the project in this series. In this article, we'll take you through a final example, Request Tracker.

    To kick off, we looked at some general principles for migrating applications to containers. Then we looked at the containerization of WordPress, and next, we discussed moving MediaWiki into a container. That project was a bit more involved than the first, with the addition of task scheduling. In this final article, we're going to consider a much more complex migration. Specifically, we'll look at Request Tracker. This service might be the most tricky because both the build and run are fairly sophisticated.

    Editor's Note: For the purpose of this article, we assume you'll be building your containers on Red Hat Enterprise Linux 8 using podman build. You may be able to use the instructions on other distributions or with other toolchains, however, some modifications may be required.

  • Using Snaps to package old software

    On Ubuntu Linux snaps are app packages for desktop, cloud and IoT that are easy to install, secure, cross‐platform and dependency‐free and their main selling point is security and confinement.

    Traditionally packaging for Ubuntu is via .deb packages but much as I try, I never find it straight forward to create or maintain deb packages and I find creating snap packages much easier.

    One use case of snaps which doesn’t get talked about much is using snaps to bring no longer supported software back to life. For example, in Ubuntu 20.10 (Groovy Gorilla) which is soon to be released there is no longer support for python2 by default and many other packages have been deprecated too in favour of newer and better replacements. This does mean though that packages which depended on these deprecated packages are not installable and will not run. Snaps can fix this.

  • Onboarding into the OpenStack Community with Git and Gerrit
  • Hot Swappable Filesystems, as Smooth as Btrfs

    Filesystems, like file cabinets or drawers, control how your operating system stores data. They also hold metadata like filetypes, what is attached to data, and who has access to that data. For windows or macOS users

    Quite honestly, not enough people consider which file system to use for their computers.

    Windows and macOS users have no valid reason to look into filesystems because they have one that’s been widely used since its inception. For Windows that’s NTFS and macOS that’s HFS+. For Linux users, there are plenty of different file system options to choose from. The current default in the Linux field is known as the Fourth Extended Filesystem or ext4.

    Currently there is discussion for changes in the filesystem space of Linux. Much like the changes to the default init systems and the switch to systemd a few years ago, there has been a push for changing the default Linux filesystem to the Btrfs. No, I'm not using slang or trying to insult you. Btrfs stands for the B-Tree file system. Many Linux users and sysadmins were not too happy with its initial changes. That could be because people are generally hesitant to change, or because they change may have been too abrupt. A friend once said, "I've learned that fear limits you and your vision. It serves as blinders to what may be just a few steps down the road for you." In this article I want to help ease the understanding of Btrfs and make the transition as smooth as butter. Let’s go over a few things first.

  • Tweak your Git config for multiple user IDs

    Git's git config command (hereafter referred to as "config") enables you to set repository or global options for Git. It has many options, and one of them, includeIf, is handy when you have dual roles using Git, for example, working full time as a developer and contributing to open source projects in your spare time. Most people in this situation don't want to use a common config for both roles or, at the very least, would rather keep certain portions of their config distinct, especially if they use the same computer in both roles.
