Linux

If we're including shell scripts/functions as "terminal commands":

• bm()
  • Zoxide wasn't quite what I wanted
  • Quick jump to a static list of directories with some alias
• mkcd()
  • Basic mkdir && cd
  • Some extra stuff for my specific workflow
• bashlib
  • My small, but helpful, "stdlib"
• gitclone.sh
  • git clone wrapper without needing to give a full URI
• md2d.sh
  • pandoc wrapper
  • I'm required to provide documentation at work in docx format, so I use this to avoid Office as much as possible

If we just mean terminal applications:

• hyperfine
• jq and yq
  • Honorable mention: xmlstarlet
• shellcheck
  • Primarily used via LSP
  • CLI tool still used when my boss sends me AI Slop scripts I have to fix

A couple of bash specific items I'm using quite often these days:

• mapfile
• printf '%(datefmt)T
  • Annoying %T doesn't expand to true ISO-8601 compliance
• (( expr ))
  • Truly saves my ass every year in Advent of Code, despite the limitations
