If you need fancier you might want to look at IPC::Run or the like.

Re^2: formatting STDOUT by Anonymous Monk on May 31, 2005 at 14:20 UTC
I call an ARSPerl function e.g. login, which only returns a structure, but opens its own stream to STDOUT. I have redirected STDOUT to a log file which i also write to using print statements in the format e.g. `Sun May 29 11:15:46 2005 Successfully generated query.` [download] but my redirect of STDOUT does not allow formatting. e.g. my line of perl code: `($control = ars_Login($arsserver, $arsuser, $arspass))` [download] produces this text, sent directly to STDOUT `[ARS.xs 201] XS_ARS_ars_Login : ars_Login(arsprod, hp_servicecall, [nu +ll]) [ARS.xs 292] XS_ARS_ars_Login : finished.` [download] I want to enforce formatting rules so any print statement, even ones from the library call, have to obey i.e. including datetime.
