i think there were actually 2 problems. the original problem on my 64-bit (home) machine is still present. when i try to run the above shell script on the 64-bit machine i get this error: --- malloc: ../bash/dispose_cmd.c:241: assertion botched free: called with unallocated block argument Aborting...Aborted --- if i add the "#!/bin/[ba]sh" line to the script it does work fine.

[Bug 299690] Re: shell scripts cannot run from bash
it looks like there are 2 problems here. if i remove everything java from my work (32-bit) computer, the problem goes away (no more lockups). that got rid of /usr/share/binfmts/jar, which i assume was the source of the lockups. that's definitely a security issue because an unprivileged user can launch a very effective DOS with just a couple of shells. unfortunately, the same didn't work for my 64-bit computer at home. i still have the same (original) problem. to sum up, i removed everything mono and java so now the only thing in binfmts is 'python2.5', but the problem is still there. i'm assuming this is still a bash problem because of the error message. ** Changed in: bash (Ubuntu) Sourcepackagename: None => bash -- shell scripts cannot run from bash https://bugs.launchpad.net/bugs/299690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 299690] Re: shell scripts cannot run from bash
Yes, I'm doing this with a 64bit 8.10 machine. What do you have in your /usr/share/binfmts directory? Perhaps something strange is in there trying to execute your script prior to bash (your script example lacks a "#!..." header as the first line, so it's possible that something other than bash is trying to execute it). -- shell scripts cannot run from bash https://bugs.launchpad.net/bugs/299690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 299690] Re: shell scripts cannot run from bash
actually, it may be related to apparmor and ssh. if i run the script locally on one of my work machines (32-bit), it works fine. if i ssh to the machine and run the script, the terminal locks up with 50% CPU usage. i have to kill the process. i've been trying to run the script through ssh on the 64-bit machine. i'll try it locally when i get home. -- shell scripts cannot run from bash https://bugs.launchpad.net/bugs/299690 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
