a find and replace within text-based files, to locate and rewrite text en mass.

syntax follows regular command line expression.

example: let's say you have a directory (with subdirs) that has say 4000 .php files.

All of these files were made via script, but uh-oh, there was a typo!

if the typo is "let's go jome!" but you meant it to say "let's go home!"

find . -name "*.php" | xargs perl -pi -e "s/let\'s\ go\ jome\!/let\'s\ go\ home\!/g"

all better :)

multiline: find . -name "*.php" | xargs perl -p0777i -e 's/knownline1\nknownline2/replaced/m'

indescriminate line replace: find ./ -name '*.php' | xargs perl -pi -e 's/\".*$\"/\new\ line\ content/g'

creates a bash function to remove certain lines from SSH known_hosts file

sometimes you got conflicts using SSH (host changing ip, ip now belongs to a different machine) and you need to edit the file and remove the offending line from known_hosts. this does it much easier.

infile search and replace on N files (including backup of the files)

the addition of ".bk" to the regular "pie" idiom makes perl create a backup of every file with the extension ".bk", in case it b0rks something and you want it back
