We do not know what $0 is. We could have changed directory as expected and the next command is hanging ya out to dry. What is the next command. Is there a "trap" that has taken the script to someplace unexpected. Also 'odd' things can happen if '.' and strange places are in your PATH. Are you running it as root via "su", as root via "su -", as root via "sudo" or as yourself. What is the first line. Is this a sh, bash or csh script or something else. Some flags may be passed, To the copy add simple commands to get you some additional information. Ideas.... $ cat bin/flubber #!/bin/bash pwd echo foo echo $0 dirname $0 cd 'dirname $0' pwd ===== $ bin/flubber /home/mydir foo bin/flubber bin bin/flubber: line 6: cd: dirname $0: No such file or directory /home/mydir ===== If it "hangs" you might run it with "strace -f -o /tmp/tracelogfile script" ===== I do recall a bug fix going into bash that fixes a standards correctness problem but has side effects because is it not "bug" compatable. You can grab an OLDer version of bash and install it in a SAFE place with rpm and try it. I just do not recall the details and they do not matter -- it is easy to test for. It is also easy to look at the change log for the bash rpm and read the bug reports. Use rpm or yum, Example using rpm: # which bash # rpm -qf /bin/bash # rpm -qi bash # rpm -q --changelog bash -- T o m M i t c h e l l Found me a new hat, now what? -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
