Returning the MD5-hash of all files in a directory to a .txt file with file name

up vote

favorite

I have a directory of pictures.

I need the MD5-hash of each file in that directory and the name of the file placed into a .txt document. This file is to be read at a later time to reference the MD5 and file name together.

Note:

I would like this to just pull all directory files with me specifying them.

I have tried playing with tar and find and I just cannot seem to find a good solution...

This is a directory example:

/Desktop/testing
RandomFilename1.png
RandomFilename2.png
RandomFilename3.png

The .txt output is:

RandomFilename1,da39a3ee5e6b4b0d3255bfef95601890afd80709
RandomFilename2,da39a3ee5e6b4b0d3255bfef95601890afd80709
RandomFilename3,da39a3ee5e6b4b0d3255bfef95601890afd80709

I've looked everywhere online with no luck.

This will be on a Linux terminal.

Do you really want the file names without the extension in the output? If so, what if two file names only differ in their extension?

You can use the following bash command:

for file in testing/*; do md5sum $file; done > res.txt

Of course you have to adjust the destination directory of res.txt.

The result could look similar to this:

8b1500ea6fe42927891fd1831bb955ba testing/Pic1.gif
73f3222889a14411a3b78675ed0bc269 testing/Pic2.gif
c5b18ef1ea1346f13f668a7ead4e4c92 testing/Pic3.gif

So the MD5 hash is followed by the filename and path.

The benefit of this solution is that you can later check the md5's with md5sum -c res.txt. I'd also suggest a simple md5sum *.gif > res.txt instead of a loop.

For what you want to do, execute md5sum and use sed or awk to transform the output

md5sum *.png | sed 's/^([0-9a-f]+) +(.+)/2,1/' >images.md5sums
md5sum *.png | awk 'print $2","$1' >image.md5sums

However, the plain output of md5sum is hash filename and is equivalent to your format. Using that standard md5sum output format is often more convenient, since you can use it directly with md5sum -c to check the hash of the files (after a copy or network transfer). Some other utilities may also expect this particular format.

I have written a small script as per the parameters defined:

cd /home/username/Desktop/testing
for F in *
do 
 echo $F, $(md5sum $F | tr --delete $F)

Example output:

test, 37346996108d322767cf65f90d43c
test.cpp, afb5b90f0021b6df4f98df40

Note: This script would show the output in terminal. To save it in file you can use > 1.txt while executing the file, for e.g.:

./test.sh > 1.txt
