# DESCRIPTION
|
||||
# An attempt to seese industrial... ops, I ment an attempt to make my
|
||||
# bash prompt nicer and save all my bash history ordered by date with
|
||||
# exit codes for later review...

|
||||
|
||||
# KNOWN BUGS:
|
||||
# - logs the previous command again on control-break, control-quit
|
||||
# - logs the last command in history on control+d (EOF) or enter
|
||||
# (could be fixed if we remember the index of the command used last time,
|
||||
# which is currently removed by 'Cmd=${Cmd:7}')
|
||||
# - does not log history from within mc (midnight commander)
|
||||
# this can be viewed as a feature too :-) The problem is that mc
|
||||
# changes PROMPT_COMMAND, hurting the prompt quite bad and
|
||||
# killing the log.
