How to revert a file in Perforce?

Question

In Perforce, how do I revert changes I have made a file?

$ p4 status
UI\FormMain.cs - reconcile to edit //UI/FormMain.cs#73

$ p4 revert UI/FormMain.cs
UI/FormMain.cs - file(s) not opened on this client.

---

In Git I do this with the command git checkout or git restore.

$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   Form.cs
#
no changes added to commit (use "git add" and/or "git commit -a")

$ git checkout Form.cs

$ git status
# On branch master
nothing to commit, working directory clean

Answer 1

If the file isn't opened, yet you have made changes to it locally, use

p4 sync -f UI/FormMain.cs

to tell Perforce to forcibly (-f) sync the copy of FormMain.cs that you have on your machine with the version from the server.

Answer 2

Instead of p4 revert UI/FormMain.cs you should call p4 revert //UI/FormMain.cs since that's the absolute path in depot notation. The file with out the leading // marks a file relative to your current location in the client workspace.
