The g option in sed's s command means it will apply the substitution multiple times per *line*. Not per file. It always applies multiple times per file, unless you restrict the line range with a prefix. hobbit:~$ printf 'foo foo\nfoo foo\n' | sed s/foo/bar/ bar foo bar foo hobbit:~$ printf 'foo foo\nfoo foo\n' | sed s/foo/bar/g bar bar bar bar
