List a User s Open Files
List a User's Open Fileslsof -uIf you want to look at the files a particular user has open (and remember that those include network connections and devices, among many others), add the -u option to lsof, followed by the username (remember that lsof must be run as root). Note In order to save space, some of the data you'd normally see when you run lsof has been removed in this and further examples. # lsof -u scott COMMAND PID USER NAMEP evolution 8603 scott /home/scott/.evolution/addressbook/local/system/addressbook.db opera 11638 scott /usr/lib/opera/9.0/opera opera 11638 scott /usr/share/fonts/truetype/msttcorefonts/Arial_Bold.ttf Even filtering out all users except one, you're left with 3,039 lines in this list. Still, some interesting items are here. For one, it appears that Evolution (an email and personal information manager program) is running all the time, without your knowledge or intention. Also, the Opera web browser is running, which is expected, and one of the web pages it's on is requiring the use of the Arial Bold font, among other files. If you administer a box used by more than person, try out lsof -u for your users. You might find that they are running programs that they shouldn't. If you're the sole user on your Linux machine, try lsof -u on yourselfyou might find that you're running programs of which you were unaware! |
