I can change the file locking ("read only") status in a file's context menu:
There's no menu item for this.
How can I create a Finder (context) menu item to set, remove, or toggle this flag more quickly?

You can create a new menu item that does that by creating a Service that receives files and folders as input in any application in Automator.
You have two implementation options. Choose one of the two Automator actions to build the Service workflow with:
The code below implements the Toggle command, as it's the most complex.
This variant uses stat
to read the flags set for the file. These are the same values as usually displayed by running ls -lO
, but stat
is a cleaner solution to read the values. The locked flag, or uchg
, has the value 0x2
, so that's what we're checking for.
chflags
is used to change the value, and growlnotify
, optional part of Growl, used to display success or error messages.
Use the following bash script code snippet as part of the Run Shell Script action:
for f in "$@"
do
let "$( stat -f "%f" "$f" ) & 0x2"
if [ $? -ne 0 ] ; then
chflags uchg "$f" || /usr/local/bin/growlnotify "Error" -m "Failed to lock $f!"
/usr/local/bin/growlnotify "Locked File" -m "$f was locked!"
else
chflags nouchg "$f" || /usr/local/bin/growlnotify "Error" -m "Failed to unlock $f!"
/usr/local/bin/growlnotify "Unlocked File" -m "$f was unlocked!"
fi
done
Configure the action to receive input as arguments.
Use the following AppleScript code snippet as part of the Run AppleScript action:
on run {input, parameters}
repeat with f in input
try
tell application "Finder" to set locked of f to (not locked of f)
on error errmsg
tell application "Finder" to display alert errmsg
end try
end repeat
end run
If the action fails, e.g. because permissions are missing, one dialog is displayed per file that failed to be changed.
