Question

I want to modify an existing Perforce label using a script that I can invoke automatically. Currently I know how to do it using the text editor option:

p4 label <label-name>

This opens up a temporary file in my default text editor, I can then enter a description, save the file and close – updates the label successfully.

However, I want to be able to do this automatically using a script. I will have variables that can be used to form my description.

I can use either a shell script or a bat script (on Windows but have Cygwin).

Perforce command line documentation on labels can be found here, but it’s not helping me.

Any ideas?

You would do something along those lines:

p4 label -o  > label.txt
sed -i 's/old/new/g' label.txt  # or any other automated method to do the modification
p4 label -i < label.txt
