Using awk in a rundeck command?

[Dan Tootill]

Hi,

I'm struggling to get Rundeck to run awk commands on a remote node, even something as basic as printing the first column from a text file e.g. running this over SSH:

# ssh myhost "awk '{print \$1}' /etc/hosts"

This works fine from the command line, but when I create a Rundeck command to do the same, it fails:

awk: syntax error near line 1
15:41:51			awk: illegal statement near line 1
15:41:52			Remote command failed with exit status 2
15:41:52			Failed: NonZeroResultCode: Remote command failed with exit status 2

I have tried escaping the single quotes and not escaping the dollar sign, nothing seems to work. Any help would be much appreciated.

Thanks,

Dam

Hi Dam,

The command string quoting is a bit cumbersome. That said, try this command string:

awk '"{print $1}"' /etc/hosts

It would be nice to have an option to control how quoting works to be more intuitive.

Thanks

Hi Alex,

Cheers for getting back to me. That succeeded but the output wasn't right; it returned the whole file rather than just the first column.

However, escaping the $ sign therein did work:

awk '"{print \$1}"' /etc/hosts

Many thanks!
