I've gotten in the habit of running the following whenever I log into an account that isn't mine, or sit down at someone elses terminal to help them with something...

some silly prompt#>tcsh
some slightly different prompt>source ~hossman/.cshrc
username@host:path>
[download]

The last prompt is because of htis line in my .cshrc file...

set prompt = "%m:%~%# "
if (`whoami` != "hossman" ) then
  set prompt "%n@%m:%~%# "
endif
[download]

why do i do this you ask?

• I allways know exactly what my PATH, and all of my other environment settings are (they're what I'm allways used to)
• I allways know exactly what directory I'm in (in the prompt)
• I allways know exactly who I am (if i'm not me, it says so in my prompt)
