Query on executing awk using SSH
Hi All,

Im trying to find the count of process running on remote server using SSH.

Below command dosen't work.

Code:
ssh -q user@host "ps -ef | grep "pattern" | grep -v 'grep' | awk '{print $2}'|wc -l"

But below command works.

Code:
ssh -q user@host "ps -ef | grep "pattern" | grep -v 'grep' | awk '{print \$2}'|wc -l"

the difference between 2 commands is $ was eacaped in second command.

Can any one explain the concept why we should escape $.
