in thread confused path

In what case would $prog1 be different if one instance is run by system() and other by exec()?

    I cannot imagine. But I cannot imagine how it were possible for which and exec, either.

      system("which $prog") would be passed through the shell. exec $prog would not be. The shell could run startup script which modify $PATH.

      perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
        Indeed. That reminds me case of cron where $PATH may be restricted unless modified.

[Corion]: Discipulus: Yes, but the chart gives some limits on whether it's really worth spending time for saving your time. If you gain enjoyment, automating is still great, but it doesn't save time ;)
[Discipulus]: Corion are you would able to realize such thing? O_O
[Corion]: In the same vein I have a script that automates Firefox to enter some data into another system. It's not faster than the people using the script if they were to do it manually, but they prefer not having to check the data and not having typos when ...
