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 -type f -printf '%20s\t%100f\t%p\n' | sort -n | uniq -Dw121 | awk -F'\t' '{print $3}' | xargs -d '\n' md5sum | uniq -Dw32 | cut -b 35- | xargs -d '\n' ls -lU

Generate MD5 of string and output only the hash checksum

Nothing special about hashing here, only the use of cut, I think, could result at fewer keystrokes. Show Sample Output

Print diagram of user/groups

Parses /etc/group to "dot" format and pases it to "display" (imagemagick) to show a usefull diagram of users and groups (don't show empty groups).

Install pip with Proxy

Installs pip packages defining a proxy

Find files and list them sorted by modification time

Works with files containing spaces and for very large directories.

list files recursively by size

Quick searching with less

This command enables the user to append a search pattern on the command line when using less as the PAGER. This is especially convenient (as the example shows) in compressed files and when searching man pages (substituting the zcat command with man, however).

Calculate N!

Capitalize first letter of each word in a string - A ruby alternative

"-n" loops around ; "-e" executes the given quoted string ; "$_" is the current line ; "split" creates an array on white space; each item of the array is "collected" to be then "capitalized" ; the array is "joined" back into a string.

Start dd and show progress every X seconds

Adjust "sleep X" to your needs. *NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while).

du with colored bar graph

A more efficient way, with reversed order to put the focus in the big ones.

Reboot without being root
