An uninvited visitor file 'mbox'












1















I check the home directory and find a extra files 'mbox'



me@alpha:~$ ls -l | grep 'mbox' | sed "s/$USER/me/g"
-rw------- 1 me me 315392 Jan 19 23:10 mbox
-rw-r--r-- 1 me me 0 Jan 19 23:10 mbox.lock


I did not create such a file intentially



me@alpha:~$ cat mbox | head -10 | sed "s/$USER/me/g"

mbox is a redundancy



How could I check where the mbox come from?

    Not an answer, but just so you know, there's no reason to do cat file | head (UUOC), you can always do head file directly instead.
