unable to extract tar file though ansible unarchive module in macOS? - macos

I have written a playbook which download the tar file & extract it to some directory in Mac.But when I run the playbook it fails with below error
"msg": "Failed to find handler for \"/Users/harmeet/.ansible/tmp/ansible-tmp-1549339698.75-251687957122076/config.tar9IXAUQ.gz\". Make sure the required command to extract the file is installed. Command \"/usr/bin/tar\" detected as tar type bsd. GNU tar required. Command \"/usr/bin/unzip\" could not handle archive.
Code for playbook
-name: Download the tar for sample config
unarchive:
src: http://someremoteurl/config.tar.gz
dest: /Users/{{ansible_user}}/.myfolder/
remote_src: yes
creates: /Users/{{ansible_user}}/.myfolder/config
If use a zip fie on remote Server such as http://someremoteurl/config.zip then this task works but for tar files it fails .
I have also installed gnu tar such as gtar & updated path in .bash_src after reviewing this question

Actually on macOS it looks for GNU based tar archive module which was not found on mac. So if you use zip module for mac in ansible it will work but for that we may need to change the playbook file & it can create issues as i am using single playbook for both mac and linux. I used GNU based tar archive module to solve this issue.
I solved this issue by below steps
Install gtar by homebrew. brew install gnu-tar
Set path of gtar in .bashsrc file otherwise it will not able to use gtar for unarchive. Usually .bashsrc exist at $HOME path. if not exist then create it.
export PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
export MANPATH="/usr/local/opt/gnu-tar/libexec/gnuman:$MANPATH"
Thanks

If your default shell is zsh, then you should put the following in ~/.zshenv:
export PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
You can check if it's working correctly by:
ansible the-hostname -m command -a "which tar"

Bash `install -d` for existing file with same name

If a part of my bash script is to copy installation files to a directory:
install -d DIRECTORY but already there's a file named DIRECTORY , bash reports an error that file already exists. How can I resolve this?
Eg:
install -d bash_completion.d . Some software, previously installed, has a file name bash_completion.d in the exact same location, so make install fails.
Is the only option to check using if-else or is there some neater way of doing this? Some theory could help.

ansible can't unarchive tar.gz file

I'm trying to unarchive a tar.gz file with ansible (which I've done quite a bit) but for some reason I can't get around this error this time.
I keep getting:
"msg": "Failed to find handler for \"/tmp/ansible_mnXJGp/internalbuildscripts1.tar.gz\". Make sure the required command to extract the file is installed. Command \"/bin/tar\" could not handle archive. Command \"/usr/bin/unzip\" could not handle archive."
what weird is that it seems to be trying to use unzip on a tar.gz file.
the task looks like this:
- name: Download build scripts
unarchive:
src: https://sblah.com/internalbuildscripts1.tar.gz
dest: /home/xxxx/buildscripts
remote_src: yes
So I had the same problem and ended up debugging the unarchive module to find out why it thought it couldn't handle the file.
TL;DR My dest was a relative path. The check that unarchive did to check if gtar would handle the file was this:
/usr/local/bin/gtar --list -C ./my/dest/path -z -f /Users/fransf/.ansible/tmp/ansible-tmp-1603283396.0748851-45418-232955281061540/source
but it did this with the working dir ALSO set to ./my/dest/path, so it was effectively trying to untar into ./my/dest/path/my/dest/path, which didn't exist!
So that was the problem in my case. I changed to using an absolute path and unarchive was happy. I do think this is a bug and apparently a test case that isn't in the unarchive test suite yet.
Debugging the Ansible module
Run your playbook with the ANSIBLE_KEEP_REMOTE_FILES environment variable set to 1 (i.e. ANSIBLE_KEEP_REMOTE_FILES=1 ansible-playbook -vvvv deploy.yml). Somewhere in the output (if you run with -vvvv) you'll see something like:
EXEC /bin/sh -c '/usr/local/Cellar/ansible/2.9.10/libexec/bin/python3.8 /Users/fransf/.ansible/tmp/ansible-tmp-1603283396.0748851-45418-232955281061540/AnsiballZ_unarchive.py && sleep 0'
Run that same command but with the explode parameter, like so:
/usr/local/Cellar/ansible/2.9.10/libexec/bin/python3.8 /Users/fransf/.ansible/tmp/ansible-tmp-1603283396.0748851-45418-232955281061540/AnsiballZ_unarchive.py explode
You'll get some output that tells you where the exploded module source was written to, e.g.
2955281061540/AnsiballZ_unarchive.py explode
Module expanded into:
/Users/fransf/.ansible/tmp/ansible-tmp-1603283396.0748851-45418232955281061540/debug_dir
Now you've got the Python source that you can either sprinkle with print statements or (this is what I did) run through an actual debugger. To run the module, use the same command as for exploding, but specify execute instead of explode:
/usr/local/Cellar/ansible/2.9.10/libexec/bin/python3.8 /Users/fransf/.ansible/tmp/ansible-tmp-1603283396.0748851-45418-232955281061540/AnsiballZ_unarchive.py execute
You can do this from the command line or from your IDE. I was already using IntelliJ Ultimate and installing the Python plugin was all I needed to be able to run this module through the debugger, set breakpoints, look at variables, and find out where it was messing up.
Hope this helps others with a similar problem.
I invite you to read #Frans answer first
I had almost the same problem:
Same error
The cause was that remote user is different from local one.
Workaround
Set ansible_remote_tmp to /tmp in the playbook
---
- name: "name of play"
hosts: all
become: true
vars:
# Setting this for unarchive to work
ansible_remote_tmp: /tmp

How to add man and zip to "git bash" installation on Windows

I am using git bash on Windows - that is git for Windows via the integrated bash. Apparently it uses the MINGW/MSYS underpinning. (Update from #VonC: It now uses msys2 since msysgit is obsolete since Q4 2015.)
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:
Navigate to this sourceforge page
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)
Navigate to to this sourceforge page
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.
2016: The zip command can be installed from GoW (Gnu On Windows). man is not provided (too big).
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.
git-archive, is prepared without any installation, can create zip-archive.
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:
Download and install 7-Zip from its official website. By default, it is installed under the directory /c/Program Files/7-Zip in Windows 10 as my case.
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 use choco as my Windows Package Manager.
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.
You can install individual GNU tools from http://gnuwin32.sourceforge.net/packages.html such as zip.
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.
Go to the following link
https://sourceforge.net/projects/gnuwin32/files/
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.
Reference Link
https://ranxing.wordpress.com/2016/12/13/add-zip-into-git-bash-on-windows/
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.
Here is my experience, I cant run and exe or .msi files in my laptop. so downloaded filed from https://github.com/bmatzelle/gow/wiki > go to download Now and Downloaded Source Code (Zip) and unzipped this file in a folder and updated path variable with folder name.
This worked out for me.
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.
Per Josip Medved's blog, the following script creates an .epub (which is a zip file), and includes a filter for stripping src/ from the files added to the zip:
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";
'
install zip
https://gnuwin32.sourceforge.net/packages/zip.htm
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

Install entire folder and files in it, RPM spec file

I have a spec file to build an rpm package, in my %install section I have this:
%install
install -m 700 foo/bar/filesToCopy/. $RPM_BUILD_ROOT/
The filesToCopy folder is a tree exactly how the package file tree should look like. It has all the sub directories a package has such as etc/..., /usr/bin, /usr/share ..., and subsquent files in those.
When building it gives me
install: omitting directory 'foo/bar/filesToCopy/'
error: Bad exit status from /var/tmp/rpm-tmp.sea6XO (%install)
Is there a way I dont have to copy each file individuallly like this:
install -m 700 foo/bar/filesToCopy/usr/bin/file1.ex $RPM_BUILD_ROOT/usr/bin/
...
As everything in filesToCopy/ is the structure as in $RPM_BUILD_ROOT/
UPDATE
I found a solution, I changed the "install -m 700" to a "cp -a"

How to zip a file using cmd line?

I want to zip a directory using the batch file command (Windows XP batch file).
For example, if I want to unzip a file means I can use the jar -xf file.zip(java) bat file command.
Like that I want a command line batch to zip a directory.
If you are using Ubuntu Linux:
Install zip
sudo apt-get install zip
Zip your folder:
zip -r {filename.zip} {foldername}
If you are using Microsoft Windows:
Windows does not come with a command-line zip program, despite Windows Explorer natively supporting Zip files since the Plus! pack for Windows 98.
I recommend the open-source 7-Zip utility which includes a command-line executable and supports many different archive file types, especially its own *.7z format which offers superior compression ratios to traditional (PKZIP) *.zip files:
Download 7-Zip from the 7-Zip home page
Add the path to 7z.exe to your PATH environment variable. See this QA:
How to set the path and environment variables in Windows
Open a new command-prompt window and use this command to create a PKZIP *.zip file:
7z a -tzip {yourfile.zip} {yourfolder}
Cross-platform Java:
If you have the Java JDK installed then you can use the jar utility to create Zip files, as *.jar files are essentially just renamed *.zip (PKZIP) files:
jar -cfM {yourfile.zip} {yourfolder}
Explanation:
* -c compress
* -f specify filename
* -M do not include a MANIFEST file
Yes, we can zip and unzip the file/folder using cmd. See the below command and simply you can copy past in cmd and change the directory and file name
To Zip/Compress File
powershell Compress-Archive D:\Build\FolderName D:\Build\FolderName.zip
To Unzip/Expand File
powershell expand-archive D:\Build\FileName.zip D:\deployments\FileName
You can use the following command:
zip -r nameoffile.zip directory
Hope this helps.
Windows 10 has tar command since 2018. It supports zip archive in default. You do not need to install any additional packages nor software.
tar.exe acvf yourfile.zip yourfolder
Compress-Archive in PowerShell does not support 2GB+ files.
The zip Package should be installed in system.
To Zip a File
zip <filename.zip> <file>
Example:
zip doc.zip doc.txt
To Unzip a File
unzip <filename.zip>
Example:
unzip mydata.zip
Zip the folder from cmd by running PowerShell:
powershell "Add-Type -A System.IO.Compression.FileSystem; [IO.Compression.ZipFile]::CreateFromDirectory('folder','archive.zip')"
Unzip:
powershell "Add-Type -A System.IO.Compression.FileSystem; [IO.Compression.ZipFile]::ExtractToDirectory('archive.zip','folder')"
Nothing listed here worked with me. This should be a very simple thing. I post my answer here, if anything because each time I search for "how to zip on the cmd window" I end up on this page, with no solution that works for me.
So here is the one that works with me: zip output_file input_files, as in the screenshot below.
