Top Forums Shell Programming and Scripting How to avoid "Too many arguments" error, when passing a long String literal as input to a command? Post 302937634 by cool.aquarian on Friday 6th of March 2015 06:44:35 PM

Do this outside awk, and pipe its output into curl. @- tells it to read from standard input instead of arguments.

Code:
awk -f program | curl --data-binary "@-" ...

This would work if I wanted to transmit all output of awk in one HTTP POST.
But if I want to POST each record extracted by awk separately, I have to perform curl from inside the awk script.
