Bash Script Requires Enter Before Any Input [duplicate]

Question

I've written a simple bash script, named ocropus:

#!/bin/bash
read filename path
...

And then i realized that I can't run it like this:

ocropus filename path

Instead, I need to run it like this:

ocropus
filename path

What can I do so I don't need to hit enter before my inputs? Thanks a lot!

Use the arguments instead of reading input. tldp.org/LDP/abs/html/othertypesv.html — tkausl

Command line arguments are in $1, $2, etc. So do:

filename=$1
path=$2

instead of

read filename path
