Finding the exact word exist

Question

I just started using dockutil and what to write a script that does the following.

Checks if the item exists on the dock. if it doesn't exist add it. if it does do nothing.

so do to check if item exist you can use the following command

~ % dockutil --find Keynote

The results would echo back with the following

Keynote was not found in Keynote was not found in /Users/$UserName/Library/Preferences/com.apple.dock.plist

So I wrote the following script to capture the input

 app='Keynote'
echo "${app}"


Test=$(dockutil --find "${app}" | tr ' ' '\n'| grep "not")

  if [[ ${Test} == "not" ]]; then

  echo " its not there "

else

  echo "its there"

fi

The problem is Keynote has the word "not" in its name which will always give me a false positive. Is there a way to look for "not found" or even just "not" from the results. Or maybe even another way of doing the if statement all together.

Answer 1

dockutil exits with 1 if the item is not found, then you can do

app='Keynote'
echo "${app}"


if ! dockutil --find "${app}"; then
    echo " its not there "
fi
