Looking to repair "Unrecognised escape sequence" if possible

[Dan White]

The recent traffic about "puppet master --compile ..." got me tinkering with it.

I found a lot of old syntax in my templates, so I added "@" in front of all the current scope variables.
That got rid of all the grumbles but one:

  Warning: Unrecognised escape sequence '\1'
  Warning: Unrecognised escape sequence '\2'

from one of my manifests/init.pp files.

The offending code can be found here:

https://github.com/mcgonagle/puppet_nist/blob/master/nist/modules/umask/manifests/init.pp

...at the end of the file,

    define umask-replace($file) {
        exec {
            "umask_replace_${file}":
                command => "/bin/sed -i -r 's/(umask)([ \t]*)[0-9]{3}/\1\2077/gi' $file",
                onlyif  => "/usr/bin/test `/bin/egrep -i '(umask|UMASK)[[:space:]]*[0-9]{3}' $file | /bin/egrep -v -i '(umask|UMASK)[[:space:]]*077' | /bin/wc -l` -ne 0";
        }
    }

Specifically, the "command" line

Besides the fact that Unrecognized is misspelled (I copied/pasted out of the command output),
can anyone suggest a fix to remove the warnings ?

Since you're in a double quoted string, I assume the \1 and \2 backreferences need to be escaped:

  "/bin/sed -i -r 's/(umask)([ \t]*)[0-9]{3}/\\1\\2077/gi' $file",

That works.  Many thanks.
