Try this:
echo $PATH | awk -F: '{print NF}'

This should pass your current PATH to awk and it will return the number of directories.

You can try out something as follows:

Code:

echo data | awk '{ print ENVIRON["USER"] }'

Read man page of awk for more info

You can pass a variable to a awk by using the -v option.. which is for variable.

It is possible and it can be a solution (i think)

#your shell script
.........................
.........................
.........................

awk -v var1=`echo $nam_var1` -v var2=`echo $nam_var2` .............

remember to delete your script var when you finish

Bye
