zsh-abbr

TIP

These are the v4 docs. For v5 docs see https://zsh-abbr.olets.dev

zsh-abbr is the zsh manager for auto-expanding abbreviations - text that when written in a terminal is replaced with other (typically longer) text. Inspired by fish shell.

For example, a frequently-run command like git checkout can be abbreviated to gco (or even co or c or anything else). Type Space after an abbreviation to expand it. Type Enter after an abbreviation to expand it and run the expansion. To prevent expansion, add Ctrl (CtrlSpace / CtrlEnter) or add a delimiter like ; after the abbreviation.

Like zsh's alias, zsh-abbr supports "regular" (i.e. command-position) and "global" (anywhere on the line) abbreviations. Like fish's abbr, zsh-abbr supports interactive creation of persistent abbreviations that are immediately available in all terminal sessions.

Run abbr help for documentation; if the package is installed with Homebrew, man abbr is also available.
