Re: passing arguments to a shell script in a here document passed to system() ?

I would use

system << "SCRIPT";
  date
  echo "arg1($value)"
SCRIPT

i.e. double quote STRING and use perl variables (quoted if needed) without introducing environment ones. You have to escape script variables, though: \$var.

If you need $@ and shifting, write the script to a file and run it :)

Thanks. I thought of that, but I'd like to avoid having to escape script variables, so I can easily slap existing, working scripts into perl using <<'SCRIPT' to avoid introducing bugs to what already works. Which I suppose begs the question as to why I wouldn't simply use the original scripts as is. Well, I sometimes like consolidating scripts into a single "swiss army knife-ish" script to simplify dragging the functionality around.	[reply]
