This article mainly introduces how to let the ps command display uid rather than the user name, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

When using the ps command, it is found that some users display the user name, and some users display the UID, such as the run-time webmaster of the nmon program, but the ps does not display the uid 500directly

Through man, it is found that an account with an 8-character user name can display the full user name, and an account with a 9-character user name shows UID.

Use the following command to solve the problem

Ps-o ruser=userForLongName-e-o pid,ppid,c,stime,tty,time,cmd

Note: "userForLongName" is entered casually, and Linux will automatically check the length of this string. If it is 15, all user names with less than 15 digits can be displayed normally.

Now run the ps command results
