Hi , all :
There is a problem on executing awk command to remote servers;
The shell test script is like this :
1. #!/bin/sh
2.
3. _CMD="ssh root@localhost"
4.
5. cpu_num="$($_CMD awk '/processor/{count["proc"]++}; END{print
count["proc"]}' /proc/cpuinfo)“
6.
7. echo $cpu_num
My root account can entry the server without the passwd.
But I found no result on the screen .
Is there some error on that script ? By the way , I googled and found use
the following method can run the right result .
1. #!/bin/sh
2.
3. _CMD="ssh root@localhost"
4.
5. cpu_num="$($_CMD << 'HERE'
6. awk '/processor/{count["proc"]++}; END{print count["proc"]}'
/proc/cpuinfo
7. HERE
8.
9. )“
10.
11. echo $cpu_num
