For example, if i have a shell program "shell1" and run "./shell1 hello world", how can I store the hello world in a variable? If I try to use read, it only accepts user input after I run ./shell1 first.

You are referring to parameters being passed to the script.
To capture them use $1 for the first parameter, $2 for the second, $3 for the third, and so forth. Use "$@" to capture all parameters into a single variable.
For example, try adding the following to your script:
param1="$1"
param2="$2"
echo "Param1 is $param1, Param2 is $param2"
allParams="$@"
echo "All params are: $allParams"
Take a look at Advanced Bash-Scripting Guide: Positional Parameters for more information.
