Shell input

#Brief The shell command and any arguments to that command appear as numbered shell variables: $0 has the string value of the command itself, something like script, ./script, /home/user/bin/script or whatever. Any arguments appear as "$1", "$2", "$3" and so on. The count of arguments is in the shell variable "$#".

#Command

$ cat myscript
#!/bin/bash
echo "$#"
echo "$0"
echo "First arg: $1"
echo "Second arg: $2"
$ ./myscript hello world
2
./myscript.sh
First arg: hello
Second arg: world
