\> This works indeed. But better use the additional quotes around $1. Just
get used to them, because $1 could contain IFS characters.
true, but in this case it doesn't really matter how shell splits words :)
>i am cheating tho, and have sh symlinked to bash. Why?
i learnt to use bash, and posix sh is not good enaugh any more. tho to be fair, most of the features i like in bash are (probably) implemented in ksh and zsh as well, i just never bothered to learn either.
I don't see any -i option documented in the sed manpage.
-i on some seds (gsed, ssed, FBSD sed, maybe others) means ''in place'' edit, that feature can be reimplemented with ''sed '....' file
new_file; mv -g new_file file'' (it also makes sure it generates
safe temp file, so doesn't overwrite any file accidentally). but it doesn't exists in OBSD sed, so his answer was 'wrong'. -- almir
