Thanks for posting that - theres a problem though - it wont remove comments that are indented, i.e. there are spaces between the comment symbol # and the left hand margin. it also doesnt work if the comment is on the same line behind a command.

Ok - i fixed it with the help of the super cool guys in the #bash irc channel, so i'll post it here for anyone who needs it.
sed '1p; /^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//'
- this will leave the shebang line alone, and will delete all comments except for the inline ones (too risky - it could delete any '#' symbols used in the script itself)

You need to create an account or log in to post comments to this site.
sed -e '/^#[^!]/d' chngcase.sh | less
would prevent the shebang line from getting removed.
