I’ve been = writing a function to run a = command, extract the first word of each line of = the = command’s output and use that as a parameter to = another command. The command’s output looks like = this:

After some trial-and-error I finally have the following = function:

      SITEMGR=3Dc:/Program\ Files/Citrix/Web\ = Interface/4.5/sitemgr.exe

      delsites() {

          for site in "${(f)$($SITEMGR = -i)}" ; {

              sitepath=3D${${=3Dsite}[1]}

              [[ -n "$sitepath" ]] && $SITEMGR -r = "WICurrent=3D$sitepath"

          }

      }

I’m new to = the = zsh = parameter expansion flags, but I’ve gathered the ${(f) will take the = command’s output a line at a time, and the = ${=3Dsite} will then split each line into words, allowing me to = grab the first word of each line.

Is = there a better (or simpler!) way to do this?  When the = command has no output, the `for’ loop is still executed once = (seemingly because the command is within = double-quotes) and is the reason for checking that the length = of $sitepath is non-zero.
