CompTIA Linux+ (XK0-004) — Question 172

An administrator receives a warning about a filesystem filling up, and then identifies a large file located at /tmp/largelogfile. The administrator deletes the file, but no space is recovered on the filesystem.
Which of the following commands would BEST assists the administrator in identifying the problem?

Answer options

• A. lsof | grep largelogfile
• B. pkill /tmp/largelogfile
• C. pgrep largelogfile
• D. ps ג€"ef | grep largelogfile

Correct answer: A

Explanation

The command 'lsof | grep largelogfile' is effective because it lists open files and helps determine if the deleted file is still held by a process, preventing space recovery. The other options do not provide the necessary information; 'pkill' and 'pgrep' deal with processes but do not check for open file handles, while 'ps -ef' only shows running processes without linking them to file usage.
