Perl is probably easiest for in-place search-and-replace: perl -pi.old -e 's/10\.1\.1\.58/10\.0\.0\.1/g' fileone filetwo ... Remove the ".old" if you don't care to save the originals. The flags are explained fairly well in `perl -h`. It doesn't get much easier than that. :) The only downside is that it recreates every file (new inode (un-hardlinks) with updated [acm]time), even if no change was actually made.
