Bash shell: Interactive Menu to Insert any String from the Tmux Scrollback Buffer Into the Shell Prompt

Reply

Imagine you're working in a tmux session, navigating logs, editing config files, or running commands, and you suddenly need to reuse a path, a variable name, or a keyword that appeared earlier on the tmux scrollback buffer. Instead of scrolling back or retyping it manually, you press Ctrl-n, type a few fuzzy letters, press enter, and the desired string from the tmux scrollback is instantly inserted at your cursor. The tmux scrollback buffer is the internal history of terminal output that tmux maintains for each pane. It consists of the lines that have scrolled off the visible screen but are … Continue reading →

Making 'cron' notify the user about a failed command by redirecting its output to stderr only when it fails (non-zero exit code)

Reply

Monitoring the success or failure of cron jobs can be challenging, especially when multiple jobs cause cron to send emails even when they don't fail. A more effective approach to handling cron job errors is to use a Bash script that directs the output to stderr only if the job fails, causing cron to notify the user about the error only when the script fails. Script overview The script provided below ensures that any command passed to it will redirect its output to a temporary file. If the command fails (i.e., returns a non-zero exit code), the script sends the … Continue reading →

Arch Linux: Preserving the kernel modules of the currently running kernel during and after an upgrade

Reply

One potential issue when upgrading the Arch Linux kernel is that the modules of the currently running kernel may be deleted. This can lead to a number of problems, including unexpected behavior, system crashes, or the inability to mount certain file systems (e.g. the kernel fails to mount a vfat file system due to the unavailability of the vfat kernel module). The Arch Linux package linux-keep-modules (also available on AUR: linux-keep-modules @AUR), written by James Cherti, provides a solution to ensure that the modules of the currently running Linux kernel remain available until the operating system is restarted. Additionally, after … Continue reading →
