Option 1<\/strong>
\nIf your Perforce server is set to security level 2 or lower you can have your trigger script run as the same user every time (typically a “background” user). Then, either have the server’s P4PASSWD environment variable set to the background user’s password,<\/p>\n

Option 2<\/strong>
\nYou can also use the -P flag to specify the password with the P4 commands issued by the script.<\/p>\n

Option 3<\/strong>
\nYou can echo the password and pipe it to the login command. Note that there is no space between the password and the pipe symbol.<\/p>\n

echo <password>| p4 login<\/p>\n

Option 4<\/strong>
\nIf you do not want to place a password in the script, you can use a text file containing the password. Make sure this password file has appropriate read and write privileges.<\/p>\n

p4 login < password.txt<\/p>\n

Option 5<\/strong>
\nA more secure method is to use ticket based authentication and a group to keep a background user “logged in” at the Perforce server:<\/p>\n

1. Create a group:<\/p>\n

p4 group always_on<\/p>\n

2. Add your background user to the “Users” field.<\/p>\n

3. Change the timeout from the default setting (12 hours), which is set in seconds. The new value depends on the server version:<\/p>\n

# 2008.1 and later: Set this value to “unlimited”. A timeout value of zero is no longer accepted.<\/p>\n

# 2005.1 to 2007.3: Set this value to zero.<\/p>\n

# 2004.2 and earlier: Set this to a very large value — but not too large, as some server versions do not handle situations where the timeout is set to exceed the “Unix Epoch”, which is approximately in the year 2038. A safe value is 315532800 seconds, which is about 10 years.<\/p>\n

# Save the group.<\/p>\n

# In your trigger script, log the background user in and run the trigger once.<\/p>\n

echo password| p4 -p server:port -u username login<\/p>\n

# If the trigger runs properly, you can remove the password line.<\/p>\n

The user now remains logged in. Since this is ticket based authentication, they remain logged in even if the server is shut down or the hardware is rebooted.<\/p>\n","protected":false},"excerpt":{"rendered":"
