So there are already a lot of MSYS tools installed - from awk to zcat. However I miss the man command and zip to compress multiple files into a zip file (unzip exists!).

Where from can I install them? I do not want to install another copy of the MINGW system! Any way just to add some pre-compiled tools to the git bash installation?

Here's another, slightly different, set of instructions to install zip for git bash on windows:

Download zip-3.0-bin.zip
In the zipped file, in the bin folder, find the file zip.exe.
Extract the file zip.exe to your mingw64 bin folder (for me: C:\Program Files\Git\mingw64\bin)
Download bzip2-1.0.5-bin.zip
In the zipped file, in the bin folder, find the file bzip2.dll
Extract bzip2.dll to your mingw64\bin folder (same folder as above: C:\Program Files\Git\mingw64\bin)

7-zip can be added to gitbash as follows:

Install 7-zip on windows.
add 7-zip folder (C:\Program Files\7-Zip) to PATH On gitbash exp: export PATH=$PATH:"C:\Program Files\7-Zip" (temporary) On Windows, adding PATH like image below (permanent)

duplicate a copy of 7z.exe to be zip.exe
reopen gitbash again. done!

This way, it works on my laptop.

If you skip step 3. you still can call zip command as 7z instead of zip

Conclusion: Gitbash is running base on windows Path, I think you can run any command that you have added to your Windows PATH.

It is to note, however, that if you only want to add the zip command from GoW, still the whole GoW system has to be downloaded and installed. Then you can delete the other commands from the bin directory, however make sure to keep the needed dlls in the directory.

Update 2021: tar/zip are by default installed on Windows 10. 7-zip based solutions are available below.

mkdir workrepo
cd workrepo
git init
cp -r [target_file_or_dir] .
git add .
git commit -m commit
git archive -o ../myarchive.zip @
cd ..
rm -rf workrepo

Following script may be usable: zip.sh foo.zip target_file_or_dir

#!/usr/bin/bash

set -eu

unset workdir
onexit() {
  if [ -n ${workdir-} ]; then
    rm -rf "$workdir"
  fi
}
trap onexit EXIT

workdir=$(mktemp --tmpdir -d gitzip.XXXXXX)


cp -r "$2" "$workdir"

pushd "$workdir"
git init
git config --local user.email "zip@example.com"
git config --local user.name "zip"
git add .
git commit -m "commit for zip"
popd

git archive --format=zip -o "$1" --remote="$workdir" HEAD

I am so glad to share my experience on this issue that I haven't known for two years since the first day I played with Groovy. My method needs to have git for Windows installed in Windows OS.

These steps are for installing 7z command-line utility, which behaves a bit differently from zip:

Run git Bash under Administrator privilege and navigate to the directory /c/Program Files/Git/mingw64/bin, you can run the command ln -s "/c/Program Files/7-Zip/7z.exe" 7z.exe

I am pretty sure it could help you a lot. Trust me!

On Windows, you can use tar instead of zip.

tar -a -c -f output.zip myfile.txt

which is same as,

zip output.zip myfile.txt

no need to install any external zip tool.

I install 7zip with choco using PowerShell (you must be admin to use Choco)

PS > choco install 7zip.install

Open another gitbash Terminal and locate the 7z.exe executable

$ which 7z
/c/ProgramData/chocolatey/bin/7z

Do a straight copy of 7z.exe to zip.exe and voila

$ cp /c/ProgramData/chocolatey/bin/7z.exe /c/ProgramData/chocolatey/bin/zip.exe

You can mimic a small subset of man behavior in the shell by mapping man <command> to <command> --help | less

Unfortunately, on my machine bash aliases won't add flags to positional arguments, it will try to run the flag as a command and fail (alias man="$1 --help" doesn't work).

And a function called man() is not allowed!

Luckily a combination of bash functions and aliases can achieve this mapping. Put the code below in your ~/.bashrc (create one if it is not there). Don't forget to source ~/.bashrc.

# man command workaround: alias can't pass flags, but can't name function man
m() {
    "$1" --help | less
}
alias man="m"

It doesn't get you the full man page, but if all you're looking for is basic info on a command and its flags, this might be all you need.

Then add "/c/Program Files (x86)/GnuWin32/bin" to PATH in your startup script like .profile, .bash_profile, .bashrc, etc.

Here are the steps you can follow.

Find out whatever command you are missing Here I need zip and bzip2 for zip command. Because zip command relies on bzip2.dll to run. Otherwise you will get error “error while loading shared libraries: ?: cannot open shared object file: No such file or directory”.
Unzip the downloaded files Here I am downloading “zip-3.0-bin.zip” for “zip.exe” and “bzip2-1.0.5-bin.zip” for “bzip2.dll” in the bin folder. /bin/.exe
Copy the command exe file into git-bash folder Here I am copying “zip.exe” and “bzip2.dll” to \Git\usr\bin.

ln -s /mingw64/bin/ziptool.exe /usr/bin/zip

steps to install SDKMAN on windows

Run Windows Terminal in Admin rights. open git bash inside. (Ctrl + Shift + 4)

winget install -e --id GnuWin32.Zip
mkdir ~/bin
cp /usr/bin/unzip ~/bin/zip
curl -s "https://beta.sdkman.io" | bash
source "/c/Users/ajink/.sdkman/bin/sdkman-init.sh"
sdk selfupdate force

After you can install Java like this.

sdk install java 17.0.2-open

Done ! :)

In msys2, I restored the functionality of git help <command> by installing man-db:

|prompt> pacman -Syu man-db
|prompt> git help archive

For zip functionality, I also use git archive (similar to yukihane's answer).

Here's yet another 7-Zip option that I didn't notice:

Create a script named zip:

$ vi ~/bin/zip

Reference 7z specifying the add command followed by the args:

#!/bin/bash
/c/Progra~1/7-Zip/7z.exe a "$@"

Finally make it executable

$ chmod ugo+x ~/bin/zip

This helped to make a ytt build script happy.

+ zip ytt-lambda-website.zip main ytt

Though this question as been answered quite thoroughly in regards to man there is one alternative to zipping that has not been highlighted here yet. @Zartc brought to my attention that there is a zip compression utility built-in: ziptool. In trying to use it however I found out it is no where near a drop-in replacement and you need to specify each individual file and folder. So I dug into the docs and experimented until I had a bash-function that can do all the heavy lifting and can be used very similar to a basic zip -qrf name * compression call:

zipWithZiptool() {
  # Docs: https://libzip.org/documentation/ziptool.html
  targetFilePath="$1"
  shift
  args=() # collect all args in an array so spaces are handled correctly
  while IFS=$'\n\r' read -r line; do
    if [[ -d "$line" ]]; then
      args+=("add_dir" "$line") # Add a single directory by name
    else
      # add_file <pathInZip> <pathToFile> <startIndex> <length>
      args+=("add_file" "$line" "$line" 0 -1)
    fi
  done <<< "$(find "$@")" # call find with every arg to return a recursive list of files and dirs
  ziptool $targetFilePath "${args[@]}" # quotation is important for handling file names with spaces
}

You can then for example zip the contents of the current directory by calling it like this:

zipWithZiptool "my.zip" *

If you are willing to install CygWin also, you can add the CygWin path to your GitBash path, and if zip is there, it will work. e.g. add

PATH=$PATH:/c/cygwin/bin
export PATH

to your .bashrc; NOTE: I would put it at the end of the path as shown, not the beginning.

Since CygWin has a UI-based installer, it's easy to add or remove applications like zip or man.

You can figure out the windows paths of each by saying

`cygpath -w /bin`

in each respective shell.

Regarding zip, you can use a following perl script to pack files:

#!/usr/bin/perl
use IO::Compress::Zip qw(:all);
$z = shift;
zip [ @ARGV ] => $z or die "Cannot create zip file: $ZipError\n";

If you make it executable, name it zip, and put it in your $PATH, you can run it like this:

zip archive.zip files...

however it will not work for directories. There is no need to install anything, as perl and all required modules are already there in the Git for Windows installation.

Regarding man, at least for git there is a documentation invoked like this:

git option --help

it will open in your default browser.

If you want to zip files without needing to install any additional tools on Windows, in a way that works both on git bash and on other *nix systems, you might be able to use perl.

perl -e '
  use strict;
  use warnings;
  use autodie;
  use IO::Compress::Zip qw(:all);
  zip [
    "src/mimetype",
    <"src/META-INF/*.*">,
    <"src/OEBPS/*.*">,
    <"src/OEBPS/chapters/*.*">
  ] => "bin/book.epub",
       FilterName => sub { s[^src/][] },
       Zip64 => 0,
  or die "Zip failed: $ZipError\n";
'

copy zip.exe and bzip2.dll from C:\Program Files (x86)\GnuWin32\bin to C:\Program Files\Git\mingw64\bin
reopen git-bash

Solutions for me were just to install zip on my terminal(bash):

$ sudo apt-get update
$ sudo apt-get install zip unzip
