awk command issue
 
Any idea on hwo to knock out the below error


root="/webroot"
echo $root | awk -v r=$root '{ print "shell root value - " r}'
awk: syntax error near line 1
awk: bailing out near line 1

The above works when using gawk and bash:
Code:
$ root="/webroot"
$ echo $root
/webroot
$ echo $root | awk -v r=$root '{ print "shell root value - " r}'
shell root value - /webroot
Which awk are you using: awk --version or ls -l $(which awk)

And which shell: grep $(id -u) /etc/passwd

My question would be ... what is the purpose of the script?

The echo is pointless. Just place BEGIN before the braces.

For that matter, what's wrong with this?

Code:
echo "shell root value - $root"
Unless you have some other, more complex need for awk that you didn't post?
