Question

I would like to know if there’s a built-in function in P4 or a way to basically only allow the p4 submit to commit ONLY when the file has a diff. Let said I have rev 1, and I want to update the file with rev 2. But I should be only allow to make this change if rev 2 is actually diff from rev 1.

I checked P4 Manual on “p4 submit” , but I don’t see much about this type of scenarios. The P4V GUI has one of these options, but how do we get this accomplish in command-line? Thanks.

p4 submit  -d "Update new drop $now" file.txt

There are a few options.

1. Add either the -f revertunchanged or -f leaveunchanged options on the p4 submit command (p4 help submit).
2. Perform a p4 revert -a command before submitting (p4 help revert)
3. Change the SubmitOptions on your client (a.k.a your workspace) so that it will always revert unchanged files before submitting (p4 help client).

P4V can be considered a wrapper of the p4 command line, i.e. it performs the exact same commands.

Tips:

• If you want to see what you commands P4V is performing, go to your preferences and change the log settings to output more detail.

• Did you notice the way I formatted the help links? If you type that (e.g. p4 help submit) into your command prompt / terminal, it will display the help for that command. If you want to see what other commands are available type p4 help commands.
