Very quick! Based only on the content sizes and the character counts of filenames. If both numbers are equal then two (or more) directories seem to be most likely identical.

if in doubt apply:

diff -rq path_to_dir1 path_to_dir2

AWK function taken from here:

If you have ever been trying to look for a list of processes based on their elapsed time you don't need to look any further.

This command lets you find the list of processes ordered in a reversed order (oldest at the top) that have been running for over an hour on your system. Any system processes are filtered out, leaving only user initiated ones in. I find it extremely useful for debugging and performance analysis.

Use the AWS CLI tools to generate a list instances, then pipe them to JQ to show only their launch time and instance id. Finally use sort to bring them out in runtime order. Find all those instances you launched months ago and have forgotten about.

I added -S to du so that you don't include /foo/bar/baz.iso in /foo, and change sorts -n to -h so that it can properly sort the human readable sizes.

function hgr() { grep --color -i "${1}" ~/.bash_history | sed -e 's/^ *//g' -e 's/ *$//g' | sort | uniq; }
du -ah | sort -h | tail

Functions: awk cut find sed sort uniq xargs

* Find all file sizes and file names from the current directory down (replace "." with a target directory as needed).

* sort the file sizes in numeric order

* List only the duplicated file sizes

* drop the file sizes so there are simply a list of files (retain order)

* calculate md5sums on all of the files

* replace the first instance of two spaces (md5sum output) with a \0

* drop the unique md5sums so only duplicate files remain listed

* Use AWK to aggregate identical files on one line.

* Remove the blank line from the beginning (This was done more efficiently by putting another "IF" into the AWK command, but then the whole line exceeded the 255 char limit).

>>>> Each output line contains the md5sum and then all of the files that have that identical md5sum. All fields are \0 delimited. All records are \n delimited.

"find ./ ..." could be replaced with "find $PWD ..." to display absolute path instead of relative path.
