I have downloaded a medical data set to use in machine learning and the files are like this:
dicom_v1.tar.gz.aa
dicom_v1.tar.gz.ab
dicom_v1.tar.gz.ac
dicom_v1.tar.gz.ad
I don't know how to extract these files. When I use WinRAR or 7-Zip, it doesn't work.
It is written in the attached ReadMe file:
To decompress this data set execute in a Unix command line:
cat dicom_archive.tar.* | tar -xzvf
How can I do this in Windows 10 as I am a beginner?
These files have been split into chunks for distribution, so you need to put them back together before you can see whether Winrar or 7-zip will be able to extract them.
Since you're using Windows, you probably want to the Powershell get-content command (which helpfully aliased to cat btw) - and since the files are chunks of a compressed archive you probably want to use the -raw argument too.
https://shellgeek.com/use-cat-equivalent-type-command-in-windows/ is a good page to read.
I would try something like this as a starting point:
PS C:\> get-content -raw dicom_v1.tar.gz.* > dicom_v1.tar.gz
According to https://pureinfotech.com/extract-tar-gz-files-windows-10/ you should be able to run tar with the z flag natively in Powershell to extract all the files from the dicom archive.

Is there a way to batch convert Collada dae files to Scenekit scn files?
My project uses approx 50 models created in sketchup that are updated regularly, these are exported to DAE but also need to be converted to SCN files for usage in xCode. I know it can be done manually via xCode and "Convert to SceneKit scene file format (scn)" but this take to much manual labour.
Based on https://the-nerd.be/2014/11/07/dynamically-load-collada-files-in-scenekit-at-runtime/ I figured out that the scntool is able to convert it via the command line and write the following script:
find ./dae -name "*.dae" | while read f ; do
inputfilename=$(basename $f)
echo $inputfilename
./scntool --convert $f --format scn --output ./scn/$inputfilename
done
for file in ./scn/*.dae; do
mv "$file" "./scn/$(basename "$file" .dae).scn"
done
#HixField has a good shell script for invoking scntool. Another way to do that is to leverage Xcode's build system, which does the same thing for any .dae files you put in a project's scnassets folder. Even if you're not bundling those files in your app, you can create a dummy Xcode target or project that contains all the assets you want to convert, and it'll convert them all whenever you build the target. (Which you could then integrate into a CI system or other automation.)
I agree with #Hixfield About everything except you need to add one more option to the scntool to get your materials correctly without need to re add all manually
scntool --convert INPUT.dae --format scn --output OUT.scn --asset-catalog-path .
The dot at the end of the command line is very important it means you will set resources to same location
If you don’t set the —asset-catalog-path . You will have no materials
So I have a very big folder full of more folders which hold files that all have their regular extension, but then with ,v after it (like .xml,v)
Is there a quick way/program to make it go through all of the folders and when it finds a ,v it'll remove the ,v from it?
Thanks
EDIT: I am running Windows 7 (64-bit). Also please remember than I am an idiot :P
Use find to list the files ending ,v. Pipe the output to a shell loop that renames the files.
${f%%,v} matches the file name without the ,v suffix.
find . -name \*,v | while read f; do mv $f ${f%%,v} ;done
Not clear, Where you have the files? (In your computer / on a server).
What is the platform (Windows / Linux) ...
There are multiple ways to solve it based on scenario (like a tiny batch file can do it in a flash if the folder is in your local computer with windows platform) ...
Description:
I am searching a very large server for files that is on a different server. right now I open command prompt and type
DIR [FILE NAME] /S/4
This returns the server location of the file with some other stuff that is not really needed.
Question:
I have a lot of files to search and one by one input into the above command could take forever. Is there a way I could input all of the names of all the files and only search once and the search results would only need to show file name and location?
First, I hope you don't mean DOS, but rather Windows cmd or batch.
You can certainly write a script that will run your DIR command once per file being sought.
But what you most likely want instead is to search once and print the path of each file found. For this you can use PowerShell's FindChildItem or the improved one posted here: http://windows-powershell-scripts.blogspot.in/2009/08/unix-linux-find-equivalent-in.html
It will be something like:
Find-ChildItem -Name "firstfile.txt|secondfile.txt|..."
Another approach is to install msys or cygwin or another Linux tools environment for Windows and use the Linux find command.
I have a bunch of shell scripts that used to run on a Linux machine. Now, we've switched over to Windows, and I need to run these scripts there. I have Cygwin installed, but is there a way to make the script run using Cygwin, but the call is made from Windows batch?
Sure. On my (pretty vanilla) Cygwin setup, bash is in c:\cygwin\bin so I can run a bash script (say testit.sh) from a Windows batch file using a command like:
C:\cygwin\bin\bash testit.sh
... which can be included in a .bat file as easily as it can be typed at the command line, and with the same effect.
One more thing - if You edited the shell script in some Windows text editor, which produces the \r\n line-endings, cygwin's bash wouldn't accept those \r. Just run dos2unix testit.sh before executing the script:
C:\cygwin\bin\dos2unix testit.sh
C:\cygwin\bin\bash testit.sh
If you have access to the Notepad++ editor on Windows there is a feature that allows you to easily get around this problem:
Open the file that's giving the error in Notepad++.
Go under the "Edit" Menu and choose "EOL Conversion"
There is an option there for "UNIX/OSX Format." Choose that option.
Re-save the file.
I did this and it solved my problems.
Hope this helps!

Just wanted to add that you can do this to apply dos2unix fix for all files under a directory, as it saved me heaps of time when we had to 'fix' a bunch of our scripts.
find . -type f -exec dos2unix.exe {} \;
I'd do it as a comment to Roman's answer, but I don't have access to commenting yet.
The existing answers all seem to run this script in a DOS console window.
This may be acceptable, but for example means that colour codes (changing text colour) don't work but instead get printed out as they are:
there is no item "[032mGroovy[0m"
I found this solution some time ago, so I'm not sure whether mintty.exe is a standard Cygwin utility or whether you have to run the setup program to get it, but I run like this:
D:\apps\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico bash.exe .\myShellScript.sh
... this causes the script to run in a Cygwin BASH console instead of a Windows DOS console.
If you don't mind always including .sh on the script file name, then you can keep the same script for Cygwin and Unix (Macbook).
To illustrate:
1. Always include .sh to your script file name, e.g., test1.sh
2. test1.sh looks like the following as an example:
#!/bin/bash
echo '$0 = ' $0
echo '$1 = ' $1
filepath=$1
3. On Windows with Cygwin, you type "test1.sh" to run
4. On a Unix, you also type "test1.sh" to run
Note: On Windows, you need to use the file explorer to do following once:
1. Open the file explorer
2. Right-click on a file with .sh extension, like test1.sh
3. Open with... -> Select sh.exe
After this, your Windows 10 remembers to execute all .sh files with sh.exe.
Note: Using this method, you do not need to prepend your script file name with bash to run
I need to write a batch file which can return the contrasted text between two csv files.
So for instance if
file1.csv has:
"a,b,c,d,e,f,g,h"
and file2.csv has:
"a,b,c,d,e"
I need to return:
",f,g,h"
and save it to a new file.
I've tried using the COMP and DIFF (GNU DiffUtils) commands, but haven't been able to get the simple output format I need. I only need the contrasted data between the two files.
Does anyone know of a free tool I can use for this?
Many thanks,
-Will
Would this be enough for you?
cat file1.csv | cut -d, -f6-
(How would the content of file2.csv need to be of influence?)
e.g.
echo "a,b,c,d,e,f,g,h" | cut -d, -f6-
f,g,h
Edit additionally, there is http://os.ghalkes.nl/dwdiff.html This will result in quite different output formats though
