csh cannot be launched

1.8k Views Asked by At

After I log into our server with bash, I try to switch to csh, but it was stuck there. I wonder what is happening at csh startup?

I don't have .cshrc file. I'm pretty sure this is related to some settings specific to my account because another user can use csh without problem. I tried to delete my .bash_profile and .bashrc and copied them from the account mentioned above, but they didn't work.

Thanks for all the comments, especially for mentioning 'csh -X'. First let me clarify a couple of things:

  1. by 'stuck' I mean no shell prompt appears after I type csh
  2. I checked top after csh, csh is in status 'S', so it's not looping infinitely
  3. `csh` is indeed a symbolic link to `tcsh`
  4. type 'x' or enter after 'csh' hangs doesn't change the situation

Here's what I got after type csh -X, any clue?

There is a high probability that your csh is symlinked to the tcsh, so please read the tcsh manual (the startup section) - there are other startup files, which the tcsh tries to load (not only the .cshrc).

Basically this hanging behavior might mean, that the shell is trying to access a machine, which is not accessible from your environment.
