Hi all,

i have a script called a.sh and within a.sh it calls b.sh.

when i do a ps -ef | grep a.sh, i get two sets of number

user_test 4225 3250 0 10:31 pts/1 00:00:00 a.sh

when i do a ps -ef | grep b.sh, i get two sets of number

user_test 4269 4225 22 10:31 pts/1 00:00:45 b.sh

why are there there two sets of numbers? which is the pid of a.sh and b.sh respectively?

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

thanks porter.

user_test 4225 3250 0 10:31 pts/1 00:00:00 a.sh
UID PID PPID C STIME TTY TIME cmd

Very easy:

Hi,

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?

Hello,

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 ?

thanks.
