How to set a toggle on linux (True or False) bash command?

I currently assigned my thinkvantage button to turn off tap to click on my trackpad, but I'd like to convert it to a toggle on/off switch.

For the moment, this is the bash command I use to turn it off (or on with CTRL):

gsettings set org.gnome.settings-daemon.peripherals.touchpad tap-to-click true
gsettings set org.gnome.settings-daemon.peripherals.touchpad tap-to-click false

In other words, ho do I turn this into a conditional toggle switch bash statement?

Presumably something like this:

#!/bin/bash
class=org.gnome.settings-daemon.peripherals.touchpad
name=tap-to-click
status=$(gsettings get "$class" "$name")
status=${status,,} # normalize to lower case; this is a modern bash extension
if [[ $status = true ]]; then
  new_status=false
else
  new_status=true
fi
gsettings set "$class" "$name" "$new_status"

Breaking it down into pieces:

• #!/bin/bash ensures that the interpreter for this script is bash, enabling extended syntax such as [[ ]].
• The syntax $( ) is "command substitution"; this runs a command, and substitutes the output of that command. Thus, if the output is true, then status=$(...) becomes status=true.
• The parameter expansion ${name,,} expands the contents of name while converting those contents to all-lowercase, and is only available in newer versions of bash. If you want to support /bin/sh or older releases of bash, consider status=$(printf '%s\n' "$status" | tr '[:upper:]' '[:lower:]') instead, or just remove this line if the output of gsettings get is always lowercase anyhow.
• The comparison [[ $status = true ]] relies on the bash extension [[ ]] (also available in other modern ksh-derived shells) to avoid the need for quoting. If you wanted it to work with #!/bin/sh, you'd use [ "$status" = true ] instead. (Note that == is allowable inside [[ ]], but is not allowable inside of [ ] on pure POSIX shells; this is why it's best not to be in the habit of using it).

Note that whitespace is important in bash! foo = bar, foo= bar and foo=bar are completely different statements, and all three of them do different things from the other two. Be sure to be cognizant of the differences in copying from this example.
