$? contains the exit code of the last shell command issued. As I recall, it is usually 0 when the execution has no errors and non-zero upon errors (hopefully that's not backward). Example:
Quote:
$dlfjdlkfdjklfd
dlfjdlkfdjklfd: not found
#echo $?

NAME
args - manipulate and output command arguments.
SYNOPSIS
args [options] args...
DESCRIPTION
This command is used to manipulate and echo command line arguments to standard out. This can include adding quotes around each argument
passed or a separator, or to output each argument on a separate line. The program source also offers a basic example of how to use shell
argument parsing and localization in ucommon.
OPTIONS
--delim=char
Set a deliminator character, such as ',', to use between each argument when outputing arguments.
--directory
If argument is a directory, list directory contents as arguments.
--follow
If argument is a directory and a symlink, follow symlinks recursively.
--lines
Output each argument on a separate line.
--quote=char|pair
Set a quote or special leading and trailing pair of characters to surround each argument with when output. A typical use might be
--quote=() to surround arguments in parenthesis.
--recursive
If argument is a directory, recursively scan directory and any subdirectory contents as arguments.
--reverse
Reverse order of arguments.
--help Outputs help screen for the user.
