From the listing the first number is the process id, the second number is that processes' parent.

i would like to clarify certain columns. I tried to man ps, and i was not able to understand the information provided. In the man pages, it states the flag -f was to print out the full-format listing, however it does not say what information comes with the full-format listing. May i know what does C, STIME,TTY and TIME means? I reckon STIME means start time and time means it has been running for how long?

i am trying to upgrade my aptitude (i mean "sudo aptitude upgrade") ! but i get an error with a resource taken by another process.

i typed ps -e and killed one process ("update-agent" i think), but it was not the one.

i can't remember the command line with grep to identify which process is holding the hand of that file.

the file is /var/lib/dpkg/lock

can i find the one using grep and something ?
