To check permissions on a file in Linux, you can use the ls -l command. This will list all the files in the current directory. The output will include the file permissions, owner, group, size, date, and filename. For example, if you type ls -l filename.txt, you would see something like this:
-rwxrwxrwx 1 username groupname 0 May 5 filename.txt
The first set of letters (rwxrwxrwx) represent the permissions set on the file.
The first set of letters (rwx) represent the owner’s permissions.
The second set of letters (rwx) represent the group’s permissions.
The third set of letters (rwx) represent the world/other users’ permissions.
The numbers indicate the number of links, the owner, the group and the size of the file.
