tcsh should clearly indicate root status after su
Last modified: 2014-03-16 22:51:31 EDT
rootfiles-8-1 (Fresh Fedora Core 3 install) My username is "beland" and my hostname is "stop". Compare the default prompts after su'ing to root, when root's shell is: bash: [root@stop beland]# tcsh: [beland@stop beland]$ I would expect the root prompt in tcsh to have either a # or a "root" in it, to clearly indicate root status. As it is for tcsh, it's the same as if I were not su'd, except for the treatment of ~. Beland
[notting@nostromo ~]$ grep ^root /etc/passwd root:x:0:0:root:/root:/bin/tcsh [notting@nostromo ~]$ su [notting@nostromo notting]# This is with FC devel; I do get the '#' distinguisher. The name comes from %n... since that's substituted in by tcsh, assigning there.
Created attachment 110419 [details] Set $prompt and $promptchars to reflect UID=0 when $USER != root I'm afraid this works "as designed". :/ "%n" is replaced by $user, which is initialized by $USER; (su) doesn't change $USER when switching to root. The easiest way to get bash-like behavior is the attached change to csh.cshrc; if that doesn't look good enough, I can talk to the upstream about changing %n behavior.
While I think the tcsh behavior is wrong, not sure it's worth the arguments with upstream. Feel free to bring it up with upstream, but change added in 2.5.40-1.
