XK0-006 Practice Question: An administrator runs the command `ls -l…
An administrator runs the command `ls -l /data/file.txt` and sees the output: `-rw-r-----+ 1 root project 1024 Mar 15 10:00 file.txt`. The administrator wants to view the current ACL entries on this file. Which command should be used?
⚠ Common exam trap
A common pitfall on the CompTIA Linux+ exam is confusing `chacl` (used for changing ACLs) with `getfacl`, or assuming a command like `lsacl` exists because of the pattern `ls` for listing, when in fact `getfacl` is the correct utility to view ACL entries.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
getfacl /data/file.txt
The `+` at the end of the permission string (`-rw-r-----+`) indicates that the file has extended ACL (Access Control List) entries beyond the standard Unix permissions. The `getfacl` command is the standard Linux utility to display the current ACL entries for a file or directory, showing user, group, and mask entries along with any named user or group ACLs.
