Shell program for beginners

Hey, i hope someone can help me with this program.

Example:

$ nameofprogram 27/04 06/05

user1 2x 0 days 2:46
user2 4x 0 days 11:42

NAME
use - Frontend to the Usepackage Environment Manager SYNOPSIS
csh and derivatives: source /usr/share/usepackage/use.csh bourne shell and derivatives: source /usr/share/usepackage/use.bsh korn shell: . /usr/share/usepackage/use.ksh use [-vs] [-f file] package ... use -l DESCRIPTION
Usepackage is an environment management program. It is based on the principle of packages - collections of executables that share a common set of necessary environment variables, such as PATH, MANPATH or LD_LIBRARY_PATH. For each given package, use sources the appropriate environment information into the current shell. The environment information is speci- fied in a configuration file, see usepackage(1). OPTIONS -v Output verbose information to the standard error stream. -s Silence warnings for un-matched packages. This is useful in a shell rc script when a package is known not to be available on all architectures that the shell is used on. -f file Specify an alternate initial configuration file. -l List available packages and groups. FILES
/usr/share/usepackage/usepackage.conf The default configuration file. /usr/share/usepackage/use.csh Shell setup for csh and derivatives. /usr/share/usepackage/use.bsh Shell setup for bourne shell and derivatives. /usr/share/usepackage/use.ksh Shell setup for ksh. /usr/bin/usepackage The underlying Usepackage executable. ENVIRONMENT
Other than the reading and re-definition of environment variables for package setup, use also uses the following environment variables for user configuration: PACKAGES_PATH Colon-separated path list giving the directories to search for configuration files. Shell-style tilde (~) user-directory escapes are expanded. HOME If present in the environment, this is used to provide the expansion for the tilde (~) user-directory. SHELL If present in the environment, the last path component of this is used for shell matching (see SYNTAX) and detecting the style of environment output that should be used, see usepackage(1).
