Perforce : Is there any command to check if client spec exist or not

Question

Actually i need write one batch script, in that first i need to check if the required client spec already exist or not? If exist then i should delete it.

Could you please let us know how can we check in a script, if the required client spec exist or not?

On Windows command line you can do something like this

set P4CLIENT=client-name
p4 clients -e %P4CLIENT% | findstr %P4CLIENT% >nul

p4 clients -e %P4CLIENT% will output all clients matching %P4CLIENT%. findstr will search the output of p4 clients for the client name and print it. The redirection to to nul will supress this output, but findstr will additionally set the %errorlevel% variable.

Some examples:

p4 clients -e existing-client | findstr existing-client >nul
echo %errorlevel%

Will return 0.

p4 clients -e does-not-exists | findstr does-not-exists >nul
echo %errorlevel%

Will return 1.

If you want to execute something, if a given client space does not exists, you can run this command:

p4 clients -e does-not-exists | findstr does-not-exists >nul || create-client.bat

If you want to execute something, if a given client space does exists, you can run this command:

p4 clients -e does-not-exists | findstr does-not-exists >nul && do-something.bat
