Undo a submitted changelist in a single step -------------------------------------------- \_\_NOTOC\_\_ ### About **p4rollback.pl** is a Perl script that automatically runs the Perforce commands needed to roll back a single changelist, as described in [Perforce KB article 14](http://kb.perforce.com/?article=14). It accepts a single submitted changelist number as an argument, and produces a new pending changelist whose effect will be to roll back the submitted changelist. See [Rollback](Rollback "wikilink") for a C++ API implementation. ### Usage `p4rollback.pl [-d] [-Di] [-Ds] [-Dt] changenumber` The **changenumber** is the submitted changelist you wish to undo. By default, the script will not roll back a given revision of a file if rolling back that revision would implicitly roll back other revisions. For example, rolling back an edit of a file that has subsequently been deleted would roll back not only the edit but the delete (re-adding the file). The **-d/-Di/-Ds/-Dt** flags override this behavior, with each **-Dx** flag overriding a specific case and **-d** overriding them all: #### -Di/-d With this option, rolling back a delete of a file that was subsequently re-added will open it for edit at the revision prior to the delete, requiring a resolve against the re-added revision(s). #### -Ds/-d With this option, rolling back an edit of a file that was subsequently deleted will open it for add at the revision prior to the edit, implicitly rolling back the delete. #### -Dt/-d With this option, rolling back an add of a file that was subsequently edited will open it for delete, implicitly rolling back the edits.
