Subshell stdout n tcsh

In bash I get the stdout of a subshell block and assign it to a varaiable like:

$ VAL="$(ls)"

How can this be done in tcsh?

Solution

  • Use backticks to get the output and use set to assign it to a variable

    examples:

        $ set val=`ls`
    $ set val=`ls | grep foo`

    to clear the variable use unset val
