Escape single quotes ssh remote command

I read any solutions for single quotes for a remote ssh command. But any work is fien.

I'm trying to

ssh root@server "ps uax|grep bac | grep -v grep | awk '{ print $2 }' > /tmp/back.tmp"

Awk doesn't work

ssh root@server "ps uax|grep bac | grep -v grep | awk \'{ print $2 }\' > /tmp/back.tmp"
....
awk: '{
awk: ^ caracter ''' inválido en la expresión

And try to put single quotas on the team, but also do not work.

In the first attempt, you use double quotes ", so you need to escape the character $:

ssh root@server "ps uax|grep bac | grep -v grep | awk '{ print \$2 }' > /tmp/back.tmp"
                                                               ▲

Alternatively, you can use:

 ps uax | grep 'ba[c]' | ...

so you don’t need a step grep -v grep.
