Writing Deskshell commands

List substitution

Certain Deskshell commands generate text output. These may be used directly, without requiring a separate process, using the form:

   var=`(basename $list)

which sets var to a list of the basenames of the files in $list without requiring another process to be run.

Functions can also generate text output for direct use using:

   `(myfunction arg1)

   `myfunction

Command and list substitutions may be nested to any depth.
