Hi , all :


There is a problem on executing awk command to remote servers;

The shell test script is like this :


  1. #!/bin/sh

  3. _CMD="ssh root@localhost"

  5. cpu_num="$($_CMD awk '/processor/{count["proc"]++}; END{print count["proc"]}' /proc/cpuinfo)“

  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

  3. _CMD="ssh root@localhost"

  5. cpu_num="$($_CMD  << 'HERE'
  6. awk '/processor/{count["proc"]++}; END{print count["proc"]}' /proc/cpuinfo
  7. HERE

  9. )“

  11. echo $cpu_num
