AWK command giving wrong input

usha rao · #1 (**permalink**) 04-01-2009

Hi all,

I have a problem with qwk command.

i have to check process status and for that i am using command
prstat -mvL 1 1
and it gives me the entire output
but when i use this command with awk like this:
prstat -mvL 1 1 | awk -F" " '{print $1,$15}'
to get first and 15th arguments.

but when i give this command i dont get the entire output which i get when i give just prstat -mvL 1 1
Any ideas why this is happening??

Thanks in advance
U

Post the output of your prstat command and the desired output within code tags (select the text with your mouse and press the # above the edit box).

Total: 524 processes, 5724 lwps, load averages: 2.11, 1.59, 2.45 "

but when i use
prstat -mvL 1 1 | awk -F" " '{print $1,$15}'

i just get
"

Code:

PID PROCESS/LWPID
1331 prstat/1
3086 java/4
3085 java/4
1327 vi/1
24127 java/8
24127 java/6
1332 awk/1
24127 java/12
24127 java/9
24127 java/15
24127 java/5
24127 java/16
24127 java/7
24127 java/10
3085 java/486"

Why is there a difference showing the number of PID's when i use simply and when i use awk.I am just printing 1st and 15th args??

Thanks

from prstat manpage:

Code:

 By  default,
                          prstat displays as many lines of output
                          that  fit in a window or terminal. When
                          you specify the -c option or direct the
                          output  to  a  file, the default values
                          for ntop and nbottom are 15 and 5.

so....you need to use something like:

Code:

#   prstat -n 60 -mvL 1 1 |  awk -F" " '{print $1,$15}'
