Description	This tool executes a system reboot, system shutdown or user logoff
Usage	Usage:  exitwin [-r/s/l]     r - reboot     s - shutdown     l - logoff
hardlink
Description	Create one or more hard links, which are the Windows equivalent to UNIX links. Only operating systems in the Windows NT family from Windows 2000 and above support them. You specify a source file or wildcards, and link(s) to it/them are made in the destination directory. If no destination is specified, the local directory is assumed. Note: The way links are made in Win32 is to the file blocks, not to the names. This means that if you make a hard link and then subsequently save one or the other paths of the link, and your editor overwrites saved files rather than opening the existing file for writing - which most do - then the link will be broken, and you'll have two independent files again. One will contain the original contents prior to the save, and the other will contain the new contents. This can be quite confounding, and renders the Win32 links as usable only for files that will not change.
Usage	Synesis Software Hard-link Creation Tool, v2.1.2.0010   USAGE 1: hardlink <src-spec> [<link-dest>]     <src-spec>  -   the source, either a single file, or wildcards     <link-dest> -   destination file, or directory. Current                     directory assumed if not specified     Creates hard link(s) from the <src-spec> to the <link-dest>   USAGE 2: hardlink -?     Displays this help   Contact Synesis Software (Pty) Ltd     at "http://synesis.com.au/systools.html",     or, via email, at "software@synesis.com.au"
intcopy

perlp
Description	Provides wildcard expansion for Windows command-line operations. (Windows, unlike UNIX, does not expand wildcards before calling programs/scripts, which means that a Perl script that receives a sequence of file names on UNIX will simply receive the wildcard string - e.g. *.h - on Windows machines. This can be very annoying. When installed - by typing "perlp -perlp_install" at the command prompt - perlp perlp intercepts script execution so that if you type "myscript.pl *.h" it will expand "*.h" before passing to the Perl interpreter. (NOTE: you have to have a Perl interpreter installed, of course ... ;))
