Question

I have an awk script which is called by:

awk -f myawkfile.awk arguments

The awk script is called into my bash script using the same mentioned call.

Can I, instead of calling the awk script declare it as a function in my bash
script. I thought it would be easy by writing an awk in front and back
ticking the whole code, then to assign a function name to call it at will.
Somehow it doesnt do the trick.

I am trying to do this because I don’t want my script to have dependency on another script.
And I am not the one who wrote the awk script. It takes a file as input , does some
stuff and gives back the modified file which is used in my script.

Using heredoc notation one can write something like this

#!/bin/bash

awk_program=$(cat << 'EOF'
    /* your awk script goes here */
EOF
)

# ...

# run awk script
awk "$awk_program" arguments

# ...
