How to get Linux user information from a User ID<\/h2>\n\n\n\n

Sometimes you may only have a unix user ID and want to the user information. To accomplish this I am going to use the getent<\/code> command. This goes through admin databases to find information about the user.<\/p>\n\n\n\n

To find the details of a user from their user ID you can use the passwd database.<\/p>\n\n\n\n

This can be accomplished using the following command.<\/p>\n\n\n\n

getent passwd THEUSERID<\/p>\n\n\n\n

Running this will return the user details from the passwd file. This includes information such as their shell, username and group ids.<\/p>\n","protected":false},"excerpt":{"rendered":"
