Yeah, but cpio is still valuable for mucking with rpm's. I often do this, when I want to extract code without installing the rpm... rpm2cpio foo.rpm | cpio -i --make-directories Granted, we don't have rpm yet, so... > TB> flip - changes CRLF endings; no equivalent in Cygwin? > > easy to do in any shell: invoke /bin/tr to do the translation > you need. e.g. for cr to lf: cat $file | /bin/tr '\015' '\ d2u and u2d are already in the cygutils package. > TB> more - sometimes I do not want the text to disappear from > TB> the screen on exit > > /bin/more is part of cygwin on my system (current as of 2 hours ago, > full install). Yep. But don't use it -- less is much better. > > TB> rev - reverse order of characters in a line > This is on my TODO list for cygutils. On linux, it is part of the util-linux package, a grab bag of random small utilities. On cygwin, cygutils is the grab bag of random small utilities: hence... I've attached the util-linux source for rev.c -- it's a bit more complex (complete?) than some of the other implementations...I'll probably use it as the basis for cygutils' version. --Chuck --------------050407020406080808000503 Content-Type: text/plain; name="rev.c" Content-Transfer-Encoding: 8bit Content-Disposition: inline; filename="rev.c" /*- * Copyright (c) 1987, 1992 The Regents of the University of California. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
