 local env. in tcsh
Hello everybody,

I am currently migrating from bash to tcsh as my standard
shell. Everything is to my satisfaction, but I miss one
feature of the good old bourne shell. How do I set a local
environment for a single command line. I.e. what is
the equivalen in tcsh/csh for the following line? UMEM_DEBUG=default,verbose ./myprog

The answer is to use 'env' command. Example:

% echo $shell

% echo $version
tcsh 6.13.00 (Astron) 2004-05-19 (i386-intel-linux) options

Proves this is tcsh.

% date
Wed Aug 10 08:09:13 GMT 2005

Shows current TZ is GMT.

% env TZ=EST5EDT date
Wed Aug 10 04:09:20 EDT 2005

Sets TZ to EST5EDT for one command only.

% date
Wed Aug 10 08:09:22 GMT 2005

Proves the TZ goes back to GMT afterwards.

Prefix with "env":

env UMEM_DEBUG=default,verbose ./myprog

Please excuse this question, but why would you do that?

It's not like "why in god's name would you do /that/?", I'd just like to

Whenever I asked people why they prefer tcsh to (arguably) more
feature-rich or grammatically consistent shells like bash, or even more so
zsh, they told me that they're used to tcsh, esp its syntax.

Now, this obviously doesn't apply to someone who is used to the bash...
