I have this line of code for the shell:

ls -1 *.mp3| awk -v here="$(cygpath -w $PWD)" -v source="$source" 'print "File Name: "$0"n"here"n"source'

Unfortunately it outputs:

File Name: Data 00053.mp3
C:UsersathenaWorkProject_10.MBT
Source: Converted from RAW

This line C:UsersathenaWorkProject_10.MBT
Should be C:UsersathenaWorkProject_100.MBT

I am now lost, a lot to learn here.

That's an issue relating to how awk treats the value passed using -v. It interprets the backslashes in the passed string.

Instead, pass it through an environment variable:

here="$(cygpath -w "$PWD")" awk ... ' print ... ENVIRON["here"] ... '

ENVIRON is an associative array in awk that contains the values of the variables in the current environment, keyed by name.

Also related to your code:

• Why *not* parse `ls` (and what to do instead)?


• When is double-quoting necessary?

  @KenIngram Did you try? a=1 b=2 c=3 awk 'BEGIN print ENVIRON["a"], ENVIRON["b"], ENVIRON["c"] '. You could obviously just export the variables instead of assigning them on the same command line as awk (but that would make them part of your script's environment too).
