Why in the world is this not working?

I know that this probably isn't the most elegant solution, but I'm just learning, so I'd appreciate some clarity around this! If you want to offer a more elegant solution, I'm all ears, too, but I'd love to solve this particular problem.

I will be keybinding this script so I can hit it whenever I want.

And here it is!

#!/bin/sh



if [ "synclient | grep TouchpadOff | grep -o -E '[0-9]+'" ]

then

        synclient TouchpadOff=0

        notify-send "Touchpad Enabled"

else

        synclient TouchpadOff=1

        notify-send "Touchpad Disabled"

When you write

 if [ "some string or other" ]

 then

the [ operator doesn't run some string or other, it just sees a non-empty string and says that is a true value.

You want

 if [ "`synclient | grep TouchpadOff | grep -o -E '[0-9]+'`" ] 

or the more modern

if [ "$(synclient | grep TouchpadOff | grep -o -E '[0-9]+')" ]

but there is really no need to see if the command produces a string as grep produces an exit code so

if synclient | grep TouchpadOff | grep -q -E '[0-9]+'

then

should do what you want. I don't know the output format of synclient, but I would expect you could combine the two greps into one without too much effort.
