In Perforce P4V I have a file in a pending changelist. I want to revert the contents of the file but keep the file in the changelist. How can I do that?
I tried Perforce's revert command but that removes the file from the changelist.
The only way to accomplish this (short of copy/pasting the original contents back into this file, but that seems silly) is to revert and reopen it. Shelving, by itself, does not revert the file. The concept of "shelve and revert" is still two operations.
This is not readily possible, as other respondents noted.
If you are okay with a multi-step solution, you could
Right-click the file in the changelist and choose "diff against have revision".
In the diff window, under "Edit" choose "Edit right/left pane" (whichever side yours is
on).
Copy the contents of the original and paste them over your edited workspace version
Save the file.
Your file now has no changes, and it is checked out in the same changelist.
Using the command line, it can be done in three stages. If you are using windows I highly recommend having a unix environment, e.g. cygwin (which is the one I used.)
Assume your changelist number is XYZ and you have shelved the files in their current revision (just for the sake of it!)
Step 1: get a list of files and put them in a temp file.
p4 describe XYZ | grep \/\/ | sed -e 's/\.\.\. //'| sed 's/#.*//' > temp
Step 2: revert all the files in the changelist
p4 revert -c XYZ //...
Step 3: check out / edit the files again
cat temp | xargs p4 edit -c XYZ
I assumed all the files are in edit mode (i.e. not an already opened file or a deleted file).
PS : delete temp, if you are fussy :)
I don't believe this can be done, even from the command line, since p4 sync (even with -f) explicitly excludes operations on open files.
The feature you're looking for is shelving. This will revert the file, but keep a shelved version in the changelist, which you (or someone else on a different client) can unshelve later.

I shelved files from another branch and unshelved them in the current branch. The problem is that now I have around 1500 files in the changelist and I want to remove the files that are identical between the branches. I've tried with Revert Unchanged Files and it reverts 0 files, but when I individually diff them I get the message that they are identical.
So, how can I remove them from the changelist if they are identical to the current version.
I don't think P4V has an equivalent to this, but this is a one-liner at the command line:
p4 diff -sr | p4 -x - revert
In P4V you can "open command prompt" to get a command prompt that already has the P4 client settings configured correctly; then just copy and paste the above.
Is there a command to open for edit all files found in a previously submitted changelist at their latest version?
I don't want to rollback a changelist; I'm looking for a shortcut to open all the files for edit instead of resorting to finding all of the files and opening them one by one.
The best I can do is format the output of p4 describe and pipe it into p4 edit.
There is an example of this on the perforce public depot...
http://public.perforce.com/wiki/Perforce_Command_Line_Recipes
Look for Open all the files in a submitted changelist for edit
There are a few flavours of this on that page, but the basic shell command is
p4 files ...#<change num>,<change num> | sed s/\#.*// | p4 -x - edit
Disclaimer: I've not actually tried this
Each time we do a build, we have to record the changelist number of source files for tracking. We have different projects (under different directories) and they are synced at different changelist number. May you please show me how can we get the changelist number of a specific directory?
Also, there's p4 changes -m1 //path/to/your/project/...#have which, if run in the client workspace that synced the files for building, will give you the highest changelist number of the files in the workspace.
You can also use the short version p4 changes -m1 #have if you don't want to specify the directory.
If you are using a shell for which "#" is a comment character like bash, remember to escape it as follows: p4 changes -m1 \#have
p4 cstat //path/to/your/project...#have |grep -B1 have|tail -n2
#thegeko, this does not require high max_scanrows perforce limits
If your build system always syncs to head on the directory before building, you can use p4 changes -m 1 //path/to/your/project/... to get the head changelist number for that directory.
If you go with this method, I would suggest running the changes command before syncing, and then explicitly syncing to that changelist. That should eliminate the chance of someone checking in between the changes command and the sync command.
I use the "lazy manual way" (aka I don't know better) within the P4V client:
Use this in the "Submitted" tab filters: //yourproject/...#>have
And it will show you which CLs you haven't synched, note the oldest one.
Remove the #>have filter and see what's the CL that came before the one you just noted.
From within the directory:
p4 changes -m1 //...#have
Using just the workspace path, p4 changes -m1 /path/to/your/workspace/...#have (or cd /path/to/your/workspace; p4 changes -m1 $(pwd)/...#have) gives you the highest changelist number of the files in the workspace. This is similar to the accepted answer above from user1054341 p4 changes -m1 //your-client-name...#have, but you don't have to remember the client name.
A path to a subdirectory in the client gives you the latest changelist in that subdirectory and its children, e.g. p4 changes -m1 /path/to/your/workspace/src/module1/...#have. This can be run from any directory within the workspace.
Omitting #have shows the latest changelist checked in to the depot.
These commands must be run from a directory in the workspace.
In my case, I just want to know what changelist number is opened (not syned to) in a specific directory. For that, I do:
p4 opened -s | cut -d' ' -f5 | uniq
I have 10k perforce files mentioned in my file.txt.
I need to open them using p4 edit command.
I expect some command like "p4 edit ?????file.txt". Can you help me to check these files out?
You can use the -x flag on p4. This is assuming a UNIX shell.
cat file.txt | p4 -x - edit
I assume you have some copy of directories structure where you have changes, and now you need to add those files to a change list. Which is impossible to do without checking them out. Am I right?
If I needed to change that much amount of files, I would do like this:
Copy all files I wanted to check in replacing read-only files (Wondows Explorer can do that)
In P4V go to a directory you need to check out files in, and then call "Reconcile offline work".
In appeared dialog choose all files.
Get new changelist with changed files being checked out.
I used this solution a couple of times - it works for added, changed and deleted files.
Just use below command to edit all files present in file.txt
p4 -x file.txt edit
One of our team member (located in different region) has shelved changes in P4 with changelist 1234.
Now, if I want to see what files are modified snf what are the changes, how can I do this?
What is the P4 command that I should use to see the changes made by our team member?
p4 describe -S 1234 should to the trick, see the documentation on describe.
To see the file content you would unshelve the files into your workspace (assuming you have a workspace for the same project your colleague is working on).
Create a new (empty) changelist with p4 change (results in e.g. 2345), then use p4 unshelve (docu) to get the modified files to your workspace:
p4 unshelve -s 1234 -c 2345
If you don't want the modified files in your workspace any longer, you can p4 revert -c 2345 them.
Using the GUI, go to Pending and remove all filters except by user, where you will put the other developer's ID. From there you should be able to see her Changelists, including the ones having shelved files. Right click on the Shelved Files icon and select Unshelve. You will have to have a workspace active that includes the files that you are trying to unshelve.
Using UI client, press Ctrl+G. Dialog window is appears. Select Changelist in combobox and input number of changelist.
Let's assume that changelist 123456 is the shelved changelist in question. As a previous answer mentioned, the way to list the files are associated with that changelist is via the p4 describe -s <changelist> command. Like so:
$ p4 describe -s 123456
Change 123456 by john.doe#JohnsBranch on 2013/10/24 15:38:10 *pending*

Once you know the file(s) in question, there are a couple of ways to diff the files without a corresponding workspace. Method #1 is to use p4 print:
$ p4 print -q //depot/branches/JohnsBranch/kernel/vm/pageutils.c#1 > /tmp/old
$ p4 print -q //depot/branches/JohnsBranch/kernel/vm/pageutils.c#=123456 > /tmp/new
$ diff /tmp/old /tmp/new # Or use kdiff3, tkdiff, etc.
...
<diff output here>
The other method is to use p4 diff2:
$ p4 diff2 //depot/branches/JohnsBranch/kernel/vm/pageutils.c#1 //depot/branches/JohnsBranch/kernel/vm/pageutils.c#=123456
...
<diff output here based on Perforce server's diff algorithm>
Both methods can be easily incorporated into the scripting language of choice.
jhwist's solution is good if you want to see the files' diffs.
If you want to see just the shelved files, use p4 describe -sS 1234.
The lower case s restricts the output from including file diffs.
If you wanted to see the actual content of the files, you could use:
p4 print <file>#=<shelved_change>
The #= means to look at the shelved change, where as # means to look at the change.
If you want to see only the list of files inside a ChangeList (whether it's a shelve, pending or submitted CL), without extra data, grep the result:
p4 describe -S 12345 | grep -oP '(?=//).*(?=#)'
In P4V UI, select
Search - > Go To
then choose type of changelist (in your case 'Pending changelist'), enter changelist number and click "OK".
You may try
p4 -ztag describe <changeno>
The description contains a string called '... shelved' if it is shelved.
