NAME

       fai-sed - call sed on a file but check for changes before writing

SYNOPSIS

       fai-sed CMD FILE

DESCRIPTION

       Execute  a sed script - here called CMD - on FILE but do not overwrite the file if nothing
       changes. If $target is defined, use it as prefix for the path to FILE.

       The exit status 0 indicates success. A nonzero value indicates failure.

OPTIONS

       -E     If fai-sed changed the file exit with 9 instead of 0.

       -n     Dry run. Print if file would have changed, but do not change it.

EXAMPLES

       Replace foo with bar in file /etc/motd.

       $ fai-sed 's/123/ABC/g; /XXX/d' /etc/motd

       Replace 123 with ABC and delete all lines which contain the string XXX.
