How do we use argc and argv (C like) in bash scripts?

The number of command line arguments is $#.  For example:

% cat foo.sh
#!/bin/sh
echo $#

% sh foo.sh
0

% sh foo.sh hello world
2

% sh foo.sh hello world
1

The argv[] equivalent is $@.

% cat foo2.sh
#!/bin/sh

for argument in $@ ;do
echo $argument
done

% sh foo2.sh
%

% sh foo2.sh hello world
hello
world
%

% sh foo2.sh hello world
hello world
%

For more details about the special variables of sh, read the sh(1)
manpage.

% man 1 sh
