in thread Recursive search and delete

"I didn't actually let it do file deletions because I'm loath to do automatic deletes until I've well tested such a script."

One nifty trick I sometimes use in situations like that is to make my script output text like this to STDOUT:

rm ABC/JKL/abc_x.xml rm ABC/JKL/abc_y.xml rm ABC/JKL/abc_z.xml

Then when I've played with it a few times, and I'm confident it's outputting the right commands, pipe the output into sh:

perl myscript.pl | sh

This is also good if you need to do a bunch of complex database changes. Just write SQL to STDOUT, and once you're sure it's OK, pipe it into your favourite command-line SQL tool.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
