Consider the result of the ls -l command in the Linux output below. What are the file permissions assigned to the sales user for the analyst.txt file?
ls –l analyst.txt
-rwxrw-r– sales staff 1028 May 28 15:50 analyst.txt
- read, write, execute
- read, write
- read only
- write only
Explanation & Hint:
The file permissions are always displayed in the User, Group and Other order. In the example displayed, the file has the following permissions:
- The dash (–) means that this is a file. For directories, the first dash would replaced with a “d”.
- The first set of characters is for user permission (rwx). The user, sales, who owns the file can read, write and execute the file.
- The second set of characters is for group permissions (rw-). The group, staff, who owns the file can read and write to the file.
- The third set of characters is for any other user or group permissions (r–). Any other user or group on the computer can only read the file.
