Re: Escape {} in shellcommnads?

[christian pearce]

Not certain how this fixed it but this is the issue I had with it.

[root@hsysnav01 root]# cat cf.awk
control:

    actionsequence = ( shellcommands )

shellcommands:

    "/bin/echo 'test test2' | /bin/awk '{ print $2 }'"
[root@hsysnav01 root]# cfagent -f ./cf.awk -IK
cf:cfengine::./cf.awk:8: Incomplete variable syntax or bracket mismatch
[root@hsysnav01 root]# vi cf.awk
[root@hsysnav01 root]# cat cf.awk
control:

    actionsequence = ( shellcommands )

shellcommands:

    "/bin/echo 'test test2' | /bin/awk '{ print ${dollar}2 }'"
[root@hsysnav01 root]# cfagent -f ./cf.awk -IK
cfengine:: Executing script /bin/echo 'test test2' | /bin/awk '{ print
$2 }'...(timeout=0,uid=-1,gid=-1)
cfengine::/bin/echo 'test: test2
cfengine:: Finished script /bin/echo 'test test2' | /bin/awk '{ print $2 }'
[root@hsysnav01 root]#


Notice I changed $2 -> ${dollar}2
