Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Although rm is protected against it, there are many commands that would wreak havoc on entering the obvious ".*" to address "dot-files". This sweet little expression excludes the dirs "." and ".." that cause the problems.

grep can be used in combination with && to run a command if a file exists.

bvi is your vi for binary editing. If your system does not have it, you can get it from

Its very useful when you do not have control over name servers and need to check DNS configuration directly, right after change. You will not need to wait for DNS propagation to verify if all records were configured properly by vendors of name servers.

It suspends to RAM: you always need your batteries for the RAM but it saves time as there is no need to slowly archive everything on your hard disk.

It works fine with me but if anyone has a nicer way, please contribute.

That's useful when you're doing some web scraping http://en.wikipedia.org/wiki/Web_scraping and you're trying to test your possibly fake user-agent.

This is the quick and dirty alternative ;)

The whole file will be emptied, this is equal to /dev/null > ~/.ssh/known_hosts

Values will depend on the driver and the hardware specifics, so you need to refer to your driver documentation for proper interpretation of those values.

Very simple and useful, you need to change the word "directory" for your directory

tar -zcvpf backup_`date +"%Y%m%d_%H%M%S"`.tar.gz `find <target> -atime +5 -type f` 2> /dev/null | parallel -X rm -f

This deals nicely with files having special characters in the file name (space ' or ").

Parallel is from https://savannah.nongnu.org/projects/parallel/
