Google Translate
substitute "example" with desired string; tl = target language (en, fr, de, hu, ...); you can leave sl parameter as-is (autodetection works fine)

draw honeycomb
$ tput setaf 1 && tput rev && seq -ws "___|" 81|fold -69|tr "0-9" "_" && tput sgr0 $ $ # (brick wall)

find the path of the java called from the command line
The output will likely point to '/etc/alternatives/java'. So find out where that points by issuing ls -l like this: ls -l /etc/alternatives/java

Generate SHA1 hash for each file in a list
List files and pass to openssl to calculate the hash for each file.

Rename files in batch

colorize comm output
It just colorizes the line based on if it has 0, 1 or 2 tabs at the beginning of the line. Won't work so well if lines already begin with tabs (too bad comm doesn't have an option to substitute \t for something else). Don't forget comm needs input files to be sorted. You can use a shortcut like this with bash: comm

list block devices
Shows all block devices in a tree with descruptions of what they are.

I finally found out how to use notify-send with at or cron
You can write a script that does this : $remind []

Watch and cat the last file to enter a directory
Great for watching things like Maildir's or any other queue directory.

Randomly run command
Randomly decide whether to run a command, or fail. It's useful for testing purposes. . Usage: ran PERCENTAGE COMMAND [ARGS] Note: In this version the percentage is required. . This is like @sesom42 and @snipertyler's commands but in a USABLE form. . e.g. In your complicated shell script, put "ran 99" before a crucial component. Now, it will fail 1% of the time allowing you to test the failure code-path. $ ran 99 my_complex_program arg1 arg2
