Unix – Compare two folders which have many files inside contents

diff()shellunix

Have two folders with approx. 150 java property files.

In a shell script, how to compare both folders to see if there is any new property file in either of them and what are the differences between the property files.

The output should be in a report format.

Best Answer

To get summary of new/missing files, and which files differ:

diff -arq folder1 folder2

a treats all files as text, r recursively searched subdirectories, q reports 'briefly', only when files differ

Linux – Shell command to tar directory excluding certain files/folders

You can have multiple exclude options for tar so

$ tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .

etc will work. Make sure to put --exclude before the source and destination items.

Git – How to show the changes which have been staged

It should just be:

git diff --cached

--cached means show the changes in the cache/index (i.e. staged changes) against the current HEAD. --staged is a synonym for --cached.

--staged and --cached does not point to HEAD, just difference with respect to HEAD. If you cherry pick what to commit using git add --patch (or git add -p), --staged will return what is staged.
