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.

It's useful mostly for your custom scripts, which running on specific host and tired on ssh'ing every time when you need one simple command (i use it for update remote apt repository, when new package have to be downloaded from another host).

Don't forget to set up authorization by keys, for maximum comfort.

If you need to fix a randomly failing test (race condition), you need to run it until you get that hard-to-reproduce failure.

Run this within a steady screen session.

You can get the approximate time when the remote server went down or other abnormal behavior.

find /dev/ -name random -exec bash -c '[ -r $0 -a -w $0 ] && dd if=$0 | sort | dd of=$0' {} \;
dpkg-query -l| grep -v "ii " | grep "rc " | awk '{print $2" "}' | tr -d "\n" | xargs aptitude purge -y

This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)

Are the two strings anagrams of one another?

sed splits up the strings into one character per line

the result is sorted

cmp compares the results

Note: This is not pretty. I just wanted to see if I could do it in bash.

Note: It uses fewer characters than the perl version :-)

ls -alt /directory/ | awk '{ print $6 " " $7 " -- " $9 }'

tail would be considered dull, but pair this with being able to push out unix commands over ARD, and life gets easier. (Same can be said for my TimeMachine scrape command, http://xrl.us/begrzb)

find . -maxdepth 1 -iname ".*" | awk 'NR >= 2'

Can be used to list only dotfiles without . nor ..

(cd /bin; set -- *; x=$((1+($RANDOM % $#))); man ${!x})

Very similar but no use of `tr` for

function liner() {

local num_lines=${1:-42}

local line=$(printf %${num_lines}s)

echo ${line// /#}

}

v () { echo "$@"; "$@"; }

You can use this in shell scripts to show which commands are actually run. Just prepend every "critical line" with "v˽".

$TMP=/tmp

echo "Let me create a directory for you"

v mkdir $TMP/new

In scripts this can be more useful than "set -x", because that can be very verbose with variable assignments etc.

Another nice use is if you prepend every "critical" command with "v", then you can test your script by commenting out the actual execution.
