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.

All with only one pipe. Should be much faster as well (sort is slow). Use find instead of ls for recursion or reliability.

Edit: case insensitive

echo '!'whammy

Seems obvious, but other seemingly simple ways to use it don't work:

echo !whammy

and

echo "!whammy"

both output:

-bash: !whammy: event not found

and this:

echo "\!whammy"

outputs:

\!whammy

with the slash :(

you can also do any combinations of quotes for a complex string:

echo "It's great to be able to use a bang ("'!'") in a command"'!'

outputs:

It's great to be able to use a bang (!) in a command!

I wrote a script called bootstrap.py to delete the database, then load a new database with initial values. With this single-line shell loop, when I need to make a schema change (which happens often in the early stages of some projects), I hit ctrl-C to stop the running Django server, then watch bootstrap.py do its thing, then watch the server restart.

Just put this line in a file that resides in your /etc/cron.d/ folder, and you're set.

The -q option is used to suppress php headers.

Deletes thousands of files at one go, I'm not able to recall the exact # of files that rm can delete at one go(apprx. around 7000.)

plays with bash arrays. instead of storing the list of files in a temp file, this stores the list in ram, retrieves the last element in the array (the last html file), then removes it.

sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d' /a/file/with/comments

Strips comments from at least bash and php scripts. Normal # and // as well as php block comments

removes all of the:

empty/blank lines

lines beginning with #

lines beginning with //

lines beginning with /*

lines beginning with a space and then *

lines beginning with */

It also deletes the lines if there's whitespace before any of the above.

Add an alias to use in .bashrc like this:

alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

Change YOUR TEXT HERE to the text you want.

On figlet -f banner, you can change it to any figlet font you have installed.

One variant for Star Wars fans could be this:

while [ 1 ]; do clear; echo 'Star Wars' | figlet -f starwars -t | while IFS="\n" read l; do echo "$l"; sleep 0.01; done; done

NOTICE: You need to install figlet.

On Ubuntu, this command is:

sudo apt-get install figlet

On Debian, this command is:

aptitude install figlet

Like the http://www.commandlinefu.com/commands/view/6327/open-file-with-sudo-when-there-is-no-write-permission, but works (in zsh; my commandlinefu is not strong enough to understand why bash don't like it) with vim options, like -O, and many input files.

There could be other mistakes.

Valid JSON is a subset of YAML; no transformation is necessary; however, YAML has many syntax features that are not valid JSON, so you can't do the reverse as easily.
