PID Number in the TOP

[clefeitosa]

Hello experts!

I'm using HPUX 11i.

Please I would like to know how can I get the PID number in the TOP... For example

host:> top -h

CPU TTY PID USERNAME PRI NI SIZE RES STATE TIME %WCPU %CPU
3 ? 13538 oracle9i 154 20 643M 7764K sleep 0:40 4.98 4.97 oracledbscmdes
1 ? 5819 root 154 20 9632K 2848K sleep 1514:55 3.17 3.16 cupsd
0 ? 7125 root 154 20 12024K 3140K sleep 433:13 2.90 2.89 netmon
0 ? 29685 oracle9i 154 20 800M 1788K sleep 33:15 2.36 2.36 oracledbslade1

In this case I need the 13538 PID number!
By command line is it possible to get this PID number?

Please, could someone give me a help?

Thanks!

You can use top -f filename to output to a file and then use awk to extract the PID's.

Thanks for reply!

Sorry, but could you show an example because my problem is exactly this... I'm not obtaining to extract the first PID on the TOP...

Thanks!!!!

Unless I'm missing something, the -f switch adds nothing to the normal display, it just redirects the output to a file. The only way I know of to get the parent is to select the process you are interested in from the top output and then run ps against it:

ps -ef |grep 13538

Ahhh, that's where the confusion is coming from. I think the author means PPID of the PID in question!!

Hi clefeitosa:

You could open the file and remove all the lines until PID inclusive, save the file and then execute:

cat | awk -F" " '{print $2}'

[A. Clay Stephenson]

The other thing that -f does is NOT SEND terminal escape sequences that you definitely don't want in your output when you are trying to parse it.

Or, 'ps -ef |grep 13538'

[Dennis Handly]

Instead of using grep with ps, you can do it directly: ps -fp 13538

But grep will find the children of that PID.

Hi,
top -h -f top.out
awk 'NF>12&&!/^CPU/ {print $3}' top.out

This to have all the PID, if you want only the first:
awk 'NF>12&&!/^CPU/ {print $3}' top.out|head -1

HTH,
Art
