determine pid from ps -ef | grep something

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?
# 2  
From the listing the first number is the process id, the second number is that processes' parent.

thanks porter.

UID PID PPID C STIME TTY TIME cmd

Very easy:
Code:
man ps

# 6  
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?

Error

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.
