|
|
|
|
|
|
# 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. |
|
|

# Avoid duplicate inclusion |
