Thanks Steven, but it doesn't works also ..

Yes, since you are double quoting you are using strings. Try using a single =
sign instead of your original double equal sign.

sign instead of your original double equal sign.
Ok, problem solved. With this compare function:
if [[ $bro_cpu_affinity == *$cpu_affinity_ok* ]]; then
works ok ...
sjt5atra, using a single =, it doesn't works ...

Re: [CentOS] OT: Howto to capture taskset output command
From: C. L. Martinez carlopm...@gmail.com
I am trying to set processor affinity for a specific process using a
shell script without result. Script:
#!/bin/sh -x
cpu_affinity_ok=2
cpu_affinity=taskset -p -c `cat /tmp/test.pid` | awk '{print
$6}'
if [ -f /tmp/test.pid ]; then
if [ $cpu_affinity == $cpu_affinity_ok ]; then
exit 0
else
taskset -p -c 2 `cat /tmp/test.pid`
fi
fi
This script doesn't works:
As you can see, function compare under if statement doesn't
works ...
This works for me:
function cpu_affinity() {
taskset -p -c $1 | awk ' { print $6 } '
}
and
PID=`cat /tmp/test.pid`
if [ $(cpu_affinity $PID) -eq $cpu_affinity_ok ]; then

The issues are to do with your variable expansion
[root@srvman ~]# cpu_affinity=taskset -p -c `cat /var/run/crond.pid` |
awk '{print $6}'
[root@srvman ~]# echo $cpu_affinity
taskset -p -c 2532 | awk '{print }'
I think your script is still broken, as you are now just looking for any
number matching $cpu_affinity_ok in $cpu_affinity. You should be able to
do an integer comparison for your if statement.

Uhmm .. You are right Tris ... The correct option is what John Doe says ..
Many thanks to all.
