Over the years, I've written DOS and Windows versions of various
Unix command-line utilities. The DOS ones are basically obsolete now,
so here are the Windows ones. Run the command with -h
for a help page, and -? for somewhat more detailed help.
- Command-line arguments may differ from whatever Unix-ish flavour
you're used to. Read the help.
- Behaviour may vary from whatever Unix-ish flavour you're used to.
- Use at your own risk. I think they work properly, based on my own
testing and use of them, but there are no guarantees.
- Except as noted, all are 32-bit utilities that should run on any
currently supported x86 or x64 version of Windows (and might also run on
some older unsupported versions). If you're a weirdo running Windows on
ARM64, you'll have to rely on Windows' built-in emulation.
- On older Windows versions (likely anything older than Windows 10 or
Windows Server 2016), you may need to install the Microsoft Visual C++
Redistributable. Try running the command first; if it fails with a
message saying that a required DLL is missing, install the x86 version
of the Visual Studio 2019 redistributable from Microsoft (or the x64 version if you're running a
64-bit version of one of these programs).
- cat: catenate files
- df: display free space on drive(s)
- du: display disk usage of directories
- find: directory search; search options include age, size,
and file attributes. Warning: Windows has its own find command
which does something very different; I'd recommend not putting my
find in the PATH. Put it somewhere else and launch it with an
explicit path, or rename it.
- hd: a version of the SCO hex dump utility, which I always
liked better than the standard Unix od command. Try it!
- mktxt: Not actually a Unix thing, but I needed to be able
to create text files (sometimes many of them, sometime large ones) to test
some of these utilities, so I wrote this program. It creates one or
more text files consisting of paragraphs of sentences of word-like
- rm: remove files
- sleep: pause for a given time
- sort: sort text from stdin. This one is available in
32- and 64-bit versions; the 64-bit version is likely quicker and can
handle larger files. Warning: Windows has its own sort
command with different syntax; I'd recommend not putting my sort
in the PATH. Put it somewhere else and launch it with an explicit
path, or rename it.
- strings: find and print text strings in binary data
- touch: update file times
- uniq: eliminate duplicate lines of text
- wc: count words, lines, and characters; counts large files
in parallel by default
- xargs: construct command lines from text; has an option to run
commands in parallel
