# bash-preexec.sh -- Bash support for ZSH-like 'preexec' and 'precmd' functions.
|
||||
# https://github.com/rcaloras/bash-preexec
|
||||
#
|
||||
#
|
||||
# 'preexec' functions are executed before each interactive command is
|
||||
# executed, with the interactive command as its argument. The 'precmd'
|
||||
# function is executed before each prompt is displayed.
|
||||
#
|
||||
# Author: Ryan Caloras (ryan@bashhub.com)
|
||||
# Forked from Original Author: Glyph Lefkowitz
|
||||
#
|
||||
# V0.5.0
|
||||
#
|
||||
|
||||
# General Usage:
|
||||
#
|
||||
# 1. Source this file at the end of your bash profile so as not to interfere
|
||||
# with anything else that's using PROMPT_COMMAND.
|
||||
#
|
||||
# 2. Add any precmd or preexec functions by appending them to their arrays:
|
||||
# e.g.
|
||||
# precmd_functions+=(my_precmd_function)
|
||||
# precmd_functions+=(some_other_precmd_function)
|
||||
#
|
||||
# preexec_functions+=(my_preexec_function)
|
||||
#
|
||||
# 3. Consider changing anything using the DEBUG trap or PROMPT_COMMAND
|
||||
# to use preexec and precmd instead. Preexisting usages will be
|
||||
# preserved, but doing so manually may be less surprising.
|
||||
#
|
||||
# Note: This module requires two Bash features which you must not otherwise be
|
||||
# using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. If you override
|
||||
# either of these after bash-preexec has been installed it will most likely break.
|
||||
|
||||
# Tell shellcheck what kind of file this is.
|
||||
# shellcheck shell=bash
|
||||
|
||||
# Make sure this is bash that's running and return otherwise.
|
||||
# Use POSIX syntax for this line:

||||
