UNIX for Dummies Questions & Answers

Hi all

(Shell: ksh Unix: NCR Unix)

Upon opening a shell, I can type a command (any command), but the shell does very little or nothing. If I cd to an unknown directory, the shell responds with "file not found", if I issue 'ls', I get no directory listing (files are present). If I issue (for example) 'cat /etc/shells' the prompt returns without displaying anything. It seems as if Unix knows about the directory structure, but fails to execute commands on the content of the structure.

If I execute a command, it appears that the command exits without actually executing.

Any ideas?

Thanks

It turned out that the userid conserned had used it's entire resource allocation. Rebooted the box, this cleared out a buch of 'hung' jobs, and now all is well again.

Was this user the only concerned or were all users affected?
Im asking you that, because it may well be that you have to do a bit of "tuning"
Is there anything in the system logs, about cannot allocate some resources?
