# IF commands in a batch file

I'm writing a small batch file to replace users' themes and charts in Office. I have the below batch file that works just fine.

cd c:\documents and settings\%username%\application data\microsoft\templates
echo Y | rmdir charts /s
mkdir charts
echo Y | del "c:\documents and settings\%username%\application data\microsoft\templates\document themes\*.*"

net use o: \\servername\sms
copy "o:\ppt themes\charts\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\charts"
copy "o:\ppt themes\Document Themes\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\document themes"

c:
net use o: /delete


Now what I want is the above to only run if it hasn't run before as we'll be pushing this out to all users for around 2 weeks to catch people that aren't in every day.

Is there any way to begin the command with something to look for one of the new themes/charts already pushed down, and if it's present, then have it not run?

Any help on this would be greatly appreciated as I'm pretty new to these batch files.

A few unrelated comments: 1) rmdir /s/q somedirectory - no unneeded prompts; 2) you can copy directly out of \\servername\share\path\file, so net use is unnecessary. – grawity May 14 '10 at 19:18
It's also possible to use the /q flag with the del command too. – afrazier May 14 '10 at 20:10
@afrazier: Yes, but del will leave the empty subdirectories behind. – grawity May 14 '10 at 20:37
Ah I tried to copy directly out of the server share and it threw up some error when I viewed it with Pause. I can't remember what the error was, though. I'll give it another shot, though, to try and tidy it up. Thanks =) – Rossaluss May 14 '10 at 23:13
@grawity: I know, but the question has an echo Y | del C:\Path\* statement, so I thought the asker might find that tidbit useful. – afrazier May 15 '10 at 0:27

if exist path\to\some\file\here goto end

.... the rest of your script here .... .... ....

:end

Note the colon preceding the label ('end', in this case) - it's important. The actual label word, 'end', isn't magic; any word (used on both places) would do.

In cmd.exe you can use goto :eof instead, which doesn't need a label. – grawity May 14 '10 at 19:15
This approach assumes some unique "version" file that you'd push out also. (Before and after the script runs, files exist in \charts and \document themes) – RJFalconer May 14 '10 at 20:13
Thanks JRobert, I'll give that a shot when I'm back in on Monday. – Rossaluss May 14 '10 at 23:14
RJFalconer: Of course just any old file wouldn't do; the presence of the file tested for needs to uniquely indicate that the update has taken place. – JRobert May 15 '10 at 10:54
The files being pushed down will have unique names not present before the push, so that shouldn't be a problem. – Rossaluss May 17 '10 at 7:54
