setting variables in tcsh temporarily
Hi, I have this simple question regarding the tcsh: in /bin/sh (Bourne shell) I can assign a value to an environment variable for just one command, like this: VARIABLE=value command e.g. DISPLAY=:0 xterm or CFLAGS=O2 make. Can this be done with tcsh as well? The only thing I can think of is this: ( setenv VARIABLE value ; command ) thus invoking a subshell, because for example the multiline variant setenv DISPLAY :0 xterm unsetenv DISPLAY forgets the (possible) original value of the variable. Thanks for any hints, this is the only Bourne-shell feature I'm missing in the C-shell.
