I cannot repeat your results with 7.6 (the version in fedora 12) or the latest coreutils.git. $ expr "uid=11008(ADILM) gid=1200(cvs),1400(build)" : \ ".*uid=[0-9]*(\(.[0-9a-z]*\)) .*" $ expr "uid=11008(ADILM) gid=1200(cvs),1400(build)" : \ ".*uid=[0-9]*(\(.[0-9a-zA-Z]*\)) .*" ADILM Perhaps you have a locale issue at play? > -bash-3.1$ rpm -qf /usr/bin/expr > coreutils-5.97-12.1.el5 That's rather old. Perhaps it might be a bug that has been fixed in the meantime, in which case, you would want to upgrade to 8.4. At any rate, there's nothing in the source code that introduces any case insensitivity, and the documentation is correct, that match and : behave identically. -- Eric Blake [email protected] +1-801-349-2682 Libvirt virtualization library http://libvirt.org
