UNIX Solaris

On Solaris 8 and 10 is there a way history command can show what time a particular command was executed.

Pls reply.

Thanks

You can append a time stamp to each user's shell history file. That would at least give you an idea in what time frame a command executed. This would be a cron job set to run ever half hour of so.

You can use something like that (ksh):

PS1='$(print -s "# $(date +%Y%m%dT%H%M%S)") $ '

That would pollute the history file though ...
