Basic Git Cheatsheet 2023-08-13 Git is a very powerful version control and a project managing tool. Every dev has to use git for projects. Below is my git cheatsheet. Basics git init — initiate a git repo in a folder git add — add file/folder to staging area git commit — commit changes git push — publish changes to remote git status — check status of git repo including staged and unstaged changes Branches You can use branches for making a copy of repo, implementing a feature and then merging it back to main branch. ...

Regex Cheatsheet 2025-06-30 Pattern Description Example ^ / $ Start/end of line (same as vim) [] Match char (can be used as OR) [abc] matches a, b, or c [^] Do NOT match this (match all except) [^abc] matches anything except a, b, c . Match any single character (including symbols and space) * Wildcard (0 or more) c.*t matches “ct”, “cat”, “cat and bat” + 1 or more (less greedy) c.+t matches “cat” and “cat and bat” but NOT “ct” ? Optional (be less strict) [T]?he matches “The” and “he” {} Specify range [0-9]{2,3} → min 2, max 3 digits. Matches 192 and 1928 but not the 9 in 19289

Autologin Linux 2023-09-09 Getting one click boot is very satisfactory but you should know the security risks associated with it. Nevertheless, here is the guide to Setup Autologin. Configuring TTY Replace ar0177417 with your username: /sbin/agetty -n -N -i -a ar0177417 tty1 38400 linux Autostarting Display Server Replace Hyprland or startx with your desired WM. For Fish Shell Add this to your fish config: if status is-login if test -z "$DISPLAY" -a "$XDG_VTNR" = 1 export LIBSEAT_BACKEND=logind exec dbus-run-session Hyprland &> /dev/null end end if status is-interactive # Commands to run in interactive sessions can go here end For Bash Shell Add this to ~/.bash_profile: ...

Boot ISOs Directly From Disk 2025-07-17 GRUB (Recommended Approach) It is assumed that ISO images are stored in the /boot-isos directory on the same filesystem as GRUB. If stored elsewhere, you must prefix the path with device identification when using the loopback command, e.g.: loopback loop (hd1,2)$iso_path Explained in greater detail below. Example GRUB Menu Entry Add the following to either: ESP/grub/grub.cfg, or /etc/grub.d/40_custom menuentry '[loopback]archlinux-2023.10.14-x86_64.iso' { set iso_path='/boot-isos/archlinux-2023.10.14-x86_64.iso' export iso_path search --set=root --file "$iso_path" loopback loop "$iso_path" root=(loop) configfile /boot/grub/loopback.cfg loopback --delete loop } Note (Fedora-specific): Fedora ISOs may fail to boot due to issues in setting volume labels when booting directly from ISO. Replace configfile /boot/grub/loopback.cfg with the following boot directives instead: ...
