passing command output from one command to the next command in cshell

HI Guys,

I hope you are well. I am trying to write a script that gets executed every time i open a shell (cshell). I have two questions about that


1) I need to enter these commands

$ echo $DISPLAY
$ setenv $DISPLAY output_of_echo_$display_command


How can i write a script with the above two commands where my second command takes the output of the first command and executes it?


2) What do i need to do to make this script run every time, i open a shell window

Note that i am doing this in the cshell.

How would i do this in the bash shell?



Please let me know if you have any questions.

THanks

[QUOTE=kaaliakahn;302597583]HI Guys,

1) I need to enter these commands

$ echo $DISPLAY
$ setenv $DISPLAY output_of_echo_$display_command[/code]

You already have the value of 'echo $DISPLAY' -- it's in $DISPLAY. Why not just setenv DISPLAY "$DISPLAY" ?

Depends what your cshell is. For tcsh, put it in your ~/.tcshrc

export DISPLAY="whatever" in your ~/.bashrc
