Scripts

Utility scripts for Unix(-like) operating systems.

Index

Portable:

• fmtw: fmt(1) wrapper to rewrap text at a given line width.
• fmtp: fmt(1) wrapper to rewrap text at a given line width while preserving a prefix (such as a comment token, e.g., // or #). 80p is an alias for fmtp -w80.
• fmtbl: fmt(1) wrapper to rewrap bulleted lists at a given line width. 72bl and 80bl are aliases for fmtbl -w72 and fmtbl -w80, respectively.
• fmts: a "smart" wrapper around fmtw, fmtp, and fmtbl, which examines the input text and picks which script to use. 72 and 80 are aliases for fmts -w72 and fmts -w80, respectively.
• et: expand(1) wrapper; accepts optional file name arguments.
• ut: unexpand(1) wrapper; accepts optional file name arguments.
• c: sed(1) wrapper to comment-out lines.
• uc: sed(1) wrapper to uncomment-out lines.
• lower and upper are trivial tr wrappers to convert text to lowercase or uppercase.
• i: indent text by one tab (default) or four spaces (with -e) or an arbitrary number of spaces (with -E n). is is an alias for i -e.
• ui: unindent text by one level (by default, four spaces and/or one tab, which works for either, as long as tabs don't follow spaces; also implements -e and -E n options to unindent spaces only).
• f: search for file names with fd or, if that's not available, with find(1).
• s: recursively search file contents with rg, ag, or grep(1), in that order of preference.
• rd2u: recursively run dos2unix(1) on all files in a directory (and its subdirectories) which contain DOS newlines.
• ci and cs are thin wrapper scripts for the cindex and csearch programs from codesearch. pci and pcs are variant wrapper scripts for using a project-specific index file.
• mktag and tag are universal-ctag wrapper scripts. mktag generates the tags file: if PWD is within a Git repository, it automatically finds the top-level directory in the repository and runs ctags -R from there. tag is a readtag(1) wrapper which converts the given tag into filename:lineno.
• mkexe: touch(1) and chmod +x paths in one command.
• no9: remove $PLAN9/bin (see plan9port) from the $PATH, if present, and run a command.
• md2htm: use pandoc to convert a Markdown file to HTML and optionally open it in a web browser.
• ddiso: dd(1) wrapper for writing an ISO to a disk.
• ddwipe: dd(1) wrapper for wiping a disk.
• Git subcommand aliases: gita (git add), gitc (git commit), gitca (git commit --amend), gitcp (git cherry-pick), gitd (git diff), gitdc (git diff --cached), gitp (git pull), git1 (git show), gits (git status), gitu (git push).
• ssh-ak-add: safely append a public key to $HOME/.ssh/authorized_keys.
• setpipefail: does set -o pipefail if the shell supports it (currently, support is assumed except for the Linux dash shell used by Debian-based distros). Does nothing useful on its own; it's meant to be sourced by other scripts.
• zfs-health: Health check-up for systems running ZFS.
• Text editor wrapper scripts which implement partial support for .editorconfig files:
  • nano-wrapper for GNU nano; also has an extra rule for Git commit messages.
  • sam-wrapper for Sam.
  • godit-wrapper for (my fork of) godit.
• vol: Volume (audio) control.
• mic: Enable or disable the microphone.
• bl: Backlight brightness control.
• nix-zsh: nix-shell(1) wrapper script which adds --run zsh to the command-line parameters.

Linux-specific:

• cputemp: prints CPU temperature
• zarc: prints ZFS ARC statistics

install.sh creates symbolic links in $HOME/bin for the scripts in this repository.
