rsync -v -r --size-only --compare-dest=../A/ B/ C/
2013-09-10 21:41:16
User: knoppix5
Functions: rsync

Assumed dir A, B, C are subdirs of the current dir

Exact syntax of the command is:

rsync -v -r --size-only --compare-dest=/path_to_A/A/ /path_to_B/B/ /path_to_C/C/

(do not omit end-slashes, since that would copy only the names and not the contents of subdirs of dir B to dir C)

You can replace --size-only with --checksum for more thorough file differences validation

Useful switch:

-n, --dry-run perform a trial run with no changes made

convert image1 image2 -resize '400x300!' MIFF:- | compare -metric AE -fuzz '10%' - null:

Outputs the number of different pixels.

2 params to increase tolerance:

* thumbnails size

* fuzz, the color distance tolerance

diff -dbByw $COLUMNS FILE1 FILE2

The normal output of 'diff' is a wonderful thing. But just sometimes, you want something that is a little more... well... readable.

This is that command.

-d - (optional) find the minimal set of changes

-b - (optional) ignore changes in the amount of whitespace

-B - (optional) ignore changes that just insert or delete blank lines

-y - this is where the magic happens! Use the side-by-side output format.

-w $COLUMNS - more magic! Instead of using 80 columns, use the current width of the terminal.

gdiff --unified=10000 input.file1 inpute.file2 | egrep -v "(^\+[a-z]|^\-[a-z])"| sort > outputfile.sorted

User: slashdot
Functions: egrep sort

This commands will make it easier to select only common items between two files being compared. If your lines start with things other than lowercase a-z, adjust this Regex appropriately. Number of lines in the output has been set to no more than 10000, and should be adjusted as needed.
