bash, (g)awk, local variables - Quoting Rules
 
To send in variable values from outside awk, you need to define them
on the command line:

awk -v mybash_a=$a -v mybash_b=$b '<awk script>'

After reading the "quoting"-rules of awk/bash I tried some different
possibilities to access bash variables inside awk.

The following code also works within a bash (script): (v 4.2.24)

a=$(<anyFile)
b="anyPattern"

awk 'BEGIN {print index("'"$a"'","'"$b"'")}'
