ansible shell escape single and double quotes

Question

I'm trying to execute this command:

ps -eo pid,args --cols=10000 | awk '/\/opt\/logstash\/logstash-1.5.3\// && $1 != PROCINFO["pid"] { print $1 }'

whith ansible -m shell module (not working example):

ansible -m shell -a '"'ps -eo pid,args --cols=10000 | awk '/\/opt\/logstash\/logstash-1.5.3\// && $1 != PROCINFO[\'pid\'] { print $1 }' '"' all

One of the ways would be to put that into a file, but still it would be nice to run as a command - any ideas?

Solution 1

Bash escaping rules will do:

ansible localhost -m shell -a "ps -eo pid,args --cols=10000 | awk '/\\/opt\\/logstash\\/logstash-1.5.3\\// && \$1 != PROCINFO[\"pid\"] { print \$1 }'"

Solution 2

Mine alternative version that worked:

ansible -m command -a "ps a |grep -E '/opt/logstash/logstash-1.5.3/vendor/jruby' " all --sudo

Check if the process are running:

ansible -m shell -a "ps aux |grep -E '/opt/logstash/logstash-1.5.3/vendor/jruby'|grep -v -e grep |wc" all

I have to confess to an aversion to grep | grep -v grep. grep -Ec '/[o]pt..' would obviate the need for both the grep -v and the wc -c.
