Why are specified parameters not passed to standard I/O when using External Hooks?

I am trying to use the External Hooks plugin as a pre-receive hook. If I try to echo my standard input, I do not see the three parameters that are supposed to be passed. That is, I do not see from_ref, to_ref, ref_name. The hook follows:


echo "My First Hook"



echo $1

exit 0

The user name and email are successful. The '$1' is empty.

What did I do wrong?

Hi Larry,

I'm no bash expert, but do you need to read the stdin in first? $1 will be the first argument to the script.

read oldrev newrev refname
echo $oldrev


Does that help?



That works. Thank you!

Normally, when executing a bash script from a bash shell, the input has been read, and one can readily reference $1 as the first argument and so on.
