linux view user's uid, gid

1.Can be viewed by/etc/passwdFile to determine your ownuidandgid

cat /etc/passwd | grep your username

example:

lan@lan:~/Desktop/File and Directory$ cat /etc/passwd |grep lan
 lan:x:1000:1000:lan,,:/home/lan:/bin/bash

The two numbers after x are uid and gid. Here uid is 1000, and gid is also 1000.

2. You can directly pass the id command

(1) Check the current user's id

id

result:

lan@lan:~/desktop/files and directory $id
 uid=1000(lan) gid=1000(lan) group=1000(lan),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),113(lpadmin),128(sambashare)

(2) Check the IDs of other users

id username

Example: View all ids of root user

lan@lan:~/Desktop/File and Directory$id root
 uid=0(root) gid=0(root) Group=0(root)
