I guess that it's because awk expects input. Either put the code in a BEGIN
block, or provide some input (empty is ok) to the script.

This is from the gawk manual:

"If an awk program has only BEGIN rules and no other rules, then the
program exits after the BEGIN rule is run. However, if an END rule
exists, then the input is read, even if there are no other rules in the
program. This is necessary in case the END rule checks the FNR and NR
variables."
