The "W" and "w" options are also useful when just trying to clean up code:
ls *pl | xargs -n 1 perl -wc
-c check syntax only (runs BEGIN and CHECK blocks)
-w enable many useful warnings (RECOMMENDED)
-W enable all warnings
Although if you have a ton o' scripts it might be useful to pipe it
into a file to look at when convenient. Keep the tips coming! They're
great.
