Find Duplicate Files (based on size, name, and md5sum)

It works extremely fast, because it calculates md5sum only on the files that have the same size and name. But there is nothing for free - it won't find duplicates with the different names. Show Sample Output

find hard linked files (duplicate inodes) recursively

If you have two sets of files that may share hard-linked files, it can be useful to identify which ones are hard links to same underlying inode (file). This command shows you all of those, sorted by inode#. In my example the two directory trees to compare share a common parent, so I run the command in that parent and just use find . to start from the current directory. If yours are in different locations, you can pass both paths to find: find /directory1 /directory2 -type f -printf '%10i %p\n' | sort | uniq -w 11 -d -D | less Show Sample Output

Prints per-line contribution per author for a GIT repository

You'll run into trouble if you have files w/ missing newlines at the end. I tried to use PAGER='sed \$q' git blame and even PAGER='sed \$q' git -p blame to force a newline at the end, but as soon as the output is redirected, git seems to ignore the pager.

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

commandline dictionary

Note: 1) Replace 'wonder' with any word you looking the meaning for in the above example 2) Need to install these packages: wordnet & wordnet-base (latter should be automatically installed because of dependency) 3) Combined size of packages is about 30MB on my old ubuntu system (I find it worth it)

Truncate 0.3 sec from an audio file using sox

Using this command one can cut a piece from the end of an audio file.

Find usb device

I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

processes per user counter

awk is evil!

Create test images

Useful to test programs and webpages.

Combine two mp3's or more into 1 long mp3

This just combines multiple mp3's into one mp3 file. Basically it is a easy join for mp3's

Mount windows share to the specified location including credentials

Replace IP address with yours IP.

Download SSL/TLS pem format cert from https web host

Show complete URL in netstat output

The -W switch of netstat makes it print complete URL of the connections, which otherwise by default is truncated to fit its default column size. Now to compensate for irregular column sizes, pipe the output to column (-t switch of column prints in tabular form). The only downside to this part is that the very first row, the header, goes pear shape.
