awk: Input line Cannot be longer than 3,000 bytes.

Shell Programming and Scripting

Guys,

I want to get the high CPU utilization from top.

I am using below code :

top -d2 >> /home/dba_monitoring/host_top_output.txt
echo "Script started `date`" > $runlog
usage=`grep "^ *$1" /home/dba_monitoring/host_top_output.txt | awk '{print $12}' | sed 's/%//'`

And getting below error message.

./cpu_consuming_queries.sh
awk: Input line Cannot be longer than 3,000 bytes.
 The input line number is 1.
 The source line number is 1.

Can anyone suggest please.

Thanks:)

in Solaris, use nawk or /usr/xpg4/bin/awk

You can also roll the bits done by grep and sed commands into your awk script:

usage=$(nawk -v N="$1" '$0 ~ "^ *"N { sub(/%/, "", $12); print $12 }' /home/dba_monitoring/host_top_output.txt)

Hi

nawk is not working as this is HP-UX.

I am getting below error :

awk: Input line
annot be longer than 3,000 bytes.
The input line number is 1. The file is /home/dba_monitoring/host_top_output.txt.
The source line number is 1.

Do you have gawk, I think it's available on HP-UX 11 and shouldn't have the 3,000 character limit.

top has a -f option that will automatically append output to a user specified logfile...so consider using that instead of >>

Hi,

I tried using gawk but getting below error.

: gawk: not found

Could you install it, then?
