md5sum output append

Hi there,

I have 2 fairly simple lines I am running and both work as expected, but I am trying to append the two of them to output a single line.

The first command get the MAC times of each file :-
Code:
find /media/Vista/Garmin/PCBSMP2/ -type f -printf "%A+ (a) %p\n%T+ (m) %p\n%C+ (c) %p\n"

And the output is :
Code:
2009-10-25+16:01:05.8765787000 (a) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt
2008-03-12+08:36:16.0000000000 (m) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt
2009-10-25+16:01:05.8765787000 (c) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt

The second command is simply calculates the md5sum of each file:-
Code:
find /media/Vista/Garmin/ -type f -print0 | xargs -0 md5sum

And the output is :-
Code:
12e6bdb52d0036cabd6f898def29dd6a  /media/Vista/Garmin/Training CenterSVE.dll
4b4f81c294b9a07479f4f4f8ff20e58c  /media/Vista/Garmin/gStart.exe
32da0f05975b3426c0ad76296abf3073  /media/Vista/Garmin/gStart_Lang.dll

So what I would like to do is have a single command that when run, not only outputs the MAC times but also appends the files md5sum.. like so
Code:
2009-10-25+16:01:05.8765787000 (a) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt 12e6bdb52d0036cabd6f898def29dd6a
2008-03-12+08:36:16.0000000000 (m) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt 12e6bdb52d0036cabd6f898def29dd6a
2009-10-25+16:01:05.8765787000 (c) /media/Vista/Garmin/PCBSMP2/eula_ENU.txt 12e6bdb52d0036cabd6f898def29dd6a

I realise that there will be duplication of the md5 hash 3 times for each file but thats cool.

Any help is appreciated.

I am not sure if this would help you but you can try:

Code:
command1 > file1.txt

will write the output of command1 to file1.txt

Now,
Code:
command2 >> file1.txt

will append command2 output to the existing file1.txt

Hi dahlia84,
Unfortunately that method wont work as the second command would append the data to the end of the file, what I really need is one line of output with the outputs of both commands written together on one line... but thanks a million for your reply.

Oh sorry, I am not on a Unix machine now but can you please try this and tell me if it works?

Code:
(command1; command2 )> filename.txt

Hi dahlia84,
No that does the same thing again, runs command one first writes to a file, and the runs command 2.

My bad. I shall give this one last try. I do not want to waste you time though.

Code:
echo `(command1; command2 )` > filename.txt

Try using echo with -n option as well because that is the option which writes the output in one single line.

If this also does not work then I am sorry! Smilie

Hi, I managed to get this to work for me. Please close.

Here is how I got it to work.

Code:
find /media/Vista/Garmin/ -type f -printf "%A+ (a),%6s, %p\n%T+ (m),%6s, %p\n%C+ (c),%6s, %p\n" | while read line;   
do   
name="$(echo $line | cut -d, -f2)";   
hash="$(echo $name | md5sum | awk -F" " '{print $1}')";   
echo $line $hash;   
done
