While it is documented to work that way doesn't mean it's a good idea to do it. cd $DIR rm -rf * For example if a script has the above 2 lines then a failure to change directory will be catastrohic (and it's something I've seen in production more than once). If you are writing your own scripts then you can avoid such things, but in a typical sysadmin team it's best to have "set -e" near the top of scripts. > As mentioned, the problem is even worse if used with other languages. e.g > the following perl script works and produces useful (and expected) output: Agreed. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
