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. If you have anything that's using the Debug Trap, change it to use # preexec.
