execute your custom commands when your program exceed $_spantime minutes
Please note it is not useful when suspend job control used, I hope some day zshall will have some build-in for this utilities.
Useful in situations you have to wait for long builds, tests, regressions and you forget to append a mail command
?? Is there is some machinism to know some program is interactive program like emacs, vi so we can bar them, like recognizing that they all may be using ncurse, or canonical/non-canonical/raw I/O usage. so we can employee `exec > `tty` > ~/outputlog ' so for long running we could be able to notify and as well as save the flying output in some logfile if some user forget to redirect it.
_spantime=15 # 15 mins, if don't want to pollute env, put its value directly.
preexec () { pgmname1=$1 pgmname2=$2 pgmname3=$3 starttime=`date +%s`; }
precmd () {
if (( $#starttime )) ; then
span=$( expr `date +%s` - $starttime )
if (( $span > ${_spantime:-15} * 60 )) ; then
your-choice-command
mail $LOGNAME@sasken.com -s "$span : $pgmname1, exit code $?" <<<"Hi $LOGNAME
command have taken more time $span seconds.
$pgmname1
exit code $?
$pgmname2
$pgmname3

unset span

set mailpath directly from mailboxes in ~/.muttrc
mailpath=( ${(f)"$(sed -n \

or
with
