On the Same Machine
If the two directories are on the same machine,
you can use either colordiff
(preferred over diff
) or git diff
to find the differences between them.
colordiff -qr dir_1 dir_2
git diff --no-index dir_1 dir_2
On Different Machines
It is a little bit tricky when the two directories are on different machines.
You have to first calculate md5sums of files in the two directories recursively,
and then compare the md5sums.
To calculate the md5sums of files in a directory recursively
and output the results into a file md5.txt
,
you can use the following command.
md5deep -r path_to_directory > md5.txt
Once you have the md5sums for the 2 directories calculated
and outputed into files (e.g., j.txt
) on the 2 machines,
you can then compare the contents of the 2 files on the 2 machines.
One way to achieve this is to run the following command on one of the machines.
ssh -p port user_name@the_other_server cat md5.txt | git diff --no-index md5.txt -
You can also copy (using rsync
or scp
) the output file on one machine to the other machine
and then compare them locally using git diff
.
