To get around the formatting issue for the "-" character on this exam, you can use the inspect tool (F12 in Chrome) > Console > type "allow pasting" > and use these strings to fix it: document.body.innerHTML = document.body.innerHTML.replace(/ג€"/g, "-") document.head.innerHTML = document.head.innerHTML.replace(/ג€"/g, "-")

A can be the only valid solution, because "lsof" shows all file used by processes and with grep we find from who is used "largelogfile" notB: because pkill is a process kill, but /tmp/largelogfile is a file not a process. notC: pgrep can be used on proces, but /tmp/largelogfile is a file not a process. notD: "ps -ef | greplargelogfile": -e is for all processess (identical to -A) and -f do full-format listing, add additional columns.
