Create an individual MD5 file for each folder in a main directory

[JonBerry]

The specs for a file delivery I'm making require an individual MD5 file per folder, with the contents of that folder being inside the MD5 file. Such as:

DAY_01 (MAIN FOLDER)
A01
-(files 1-1000)
-md5 for files 1-1000
A02
-files 1001-2000
-md5 for files 1001-2000

And so on. Is there a script or program that can make those MD5 files automatically or do I hace to go and do each one individually? Thanks

You didn't specify what kind of interface you are looking for. Are you comfortable with the shell in Terminal?

Create the following text file in your home directory.

#!/bin/bash

function do_sum
{
	local $ans;

	for f in $@ ;
	do
		if [ -f $f ];
		then
			ans=`openssl md5 < $f`
			echo "$ans $f" >> md5sums.out
		fi
	done
}

s=$(pwd)

cd $1
if [ -f md5sums.out ]; then 
	rm -f md5sums.out
fi
do_sum *
cd $s

If you call this file "do_sums.sh". Then:

chmod +x do_sums.sh
find MAIN_DIR -type d -exec ~/do_sums.sh {} \;

... where MAIN_DIR is the top level directory in question. This script will create a file "md5sums.out" in each directory.

I tried that, created the do_sums.sh and put it in the home folder as requested. Ran the terminal command though and got and error like this:

/Tusers/jberry/do_sums.sh: line 1: {rtf1ansiansicpg1252cocoartf1038cocoasubrtf360: command not found
/Tusers/jberry/do_sums.sh: line 2: syntax error near unexpected token `}'
/Tusers/jberry/do_sums.sh: line 2: `{\fonttbl\f0\fswiss\fcharset0 Helvetica;}'

I'm a complete novice when deciphering terminal codes so any help would appreciated. Thanks!

That's RTF, not a text file. And the script takes a parameter, the name of the directory where you want to generate the file.

[JonBerry]

Fixed the rtf issue. Here's what I've been doing, and let me know how completely far off I am:

-copy do_sums.sh (renamed from a text file) into the home directory (under my user)
-open terminal and cd into the main directory above the folder I want to make MD5's of. So:

FOLDER_1
-MAIN FOLDER <---CD into this via terminal)
-Shot1
-Shot2
-etc.

type in the commands you listed with /VOLUMES/V1/MAIN_FOLDER in place of MAIN_DIR

Still get an issues of No such file or directory with regards to the do_sums.sh:

find: /Tusers/jberry/do_sums.sh: No such file or directory.

Any thoughts? Am I in the right place?

Maybe you have spaces in the filenames? My initial script wouldn't have handled that well. Also, be careful of case. Although the filesystem may not be case-sensitive, the shell is often case sensitive. Finally, be sure to double-check the name of your script. Here's another try:

File ~/do_sums.sh

#!/bin/bash

s=$(pwd)

cd "$@"
for i in *; do
	if [ -f "$i" ]; then
		ans=$(openssl md5 < "$i")
		echo "$ans $i" >> md5sums.out
	fi
done
cd "$s"

Make sure to "chmod +x do_sums.sh" the script after it is created.

The lines starting with "$" are the commands entered. The rest are the output. "ls" means list files
"cat" means print the contents of a file.
"find" means to find files and do some operation on them.

$ ls -l ~/do_sums.sh
-rwxr-xr-x  1 user  staff  145 Nov 12 22:39 do_sums.sh*

Make sure the "x" shows up as above.

Here's an example. I'm using an external Flash drive with a FAT filesystem.

$ ls -l -R "/Volumes/NO NAME/test"

drwxrwxrwx  1 user  staff  4096 Nov 12 22:45 Dir 1/
