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?

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

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?
