hb blinks, hc does a reverse color with background.. both very nice.

Run this:

Your welcome ;)

From my bash profile - http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

The shell has perfectly adequate pattern matching for simple expressions.

For those days when you need to know if something is happening because the day ends in "y".

Removes any whitespace characters at the beginning of a line.

extension to tali713's random fact generator. It takes the output & sends it to notify-osd. Display time is proportional to the lengh of the fact.

Though without infinite time and knowledge of how the site will be designed in the future this may stop working, it still will serve as a simple straight forward starting point.

This uses the observation that the only item marked as strong on the page is the single logical line that includes the italicized fact.

If future revisions of the page show failure, or intermittent failure, one may simply alter the above to read.

The file lastfact, can then be examined whenever the command fails.

use curl and sed to shorten an url via goo.gl

Use color escape sequences and sed to colorize the output of svn stat -u.

Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc.

Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this.

Make sure your server's date is correct, otherwise insert your own serial number.

should usually follow this command.

This one uses dictionary.com

The original was a little bit too complicated for me. This one does not use any variables.

Looks up a word on merriam-webster.com, does a screen scrape for the FIRST audio pronunciation and plays it.

USAGE: Put this one-liner into a shell script (e.g., ~/bin/pronounce) and run it from the command line giving it the word to say:

If the word isn't found in merriam-webster, no audio is played and the script returns an error value. However, M-W is a fairly complete dictionary (better than howjsay.com which won't let you hear how to pronounce naughty words).

ASSUMPTIONS: GNU's sed (which supports -r for extended regular expressions) and Linux's aplay. Aplay can be replaced by any program that can play .WAV files from stdin.

KNOWN BUGS: only the FIRST pronunciation is played, which is problematic if you wanted a particular form (plural, adjectival, etc) of the word. For example, if you run this:

you'll hear a voice saying "onomatopoeia".

Playing the correct form of the word is possible, but doing so might make the screen scraper even more fragile than it already is. (The slightest change to the format of m-w.com could break it).

It is helpful to know the current limits placed on your account, and using this shortcut is a quick way to figuring out which values to change for optimization or security.

Here's the result of this command:

You WILL have problems if the files have the same name.

Use cases: consolidate music library and unify photos (especially if your camera separates images by dates).

After running the command and verifying if there was no name issues, you can use

to remove now empty subdirectories.

using find's exec option instead of a for loop and using sed's -i option for inplace replacement. no need to do the file swap.

Use sed to edit in-place a list of files returned by find.

Do a recursive (-r) search with grep for all files where your old mail address is mentioned (-l shows only the file names) and use sed to replace it with your new address. Works with other search/replacement patterns too.

I took matthewbauer's cool one-liner and rewrote it as a shell function that returns all the suggestions or outputs "OK" if it doesn't find anything wrong. It should work on ksh, zsh, and bash. Users that don't have tee can leave that part off like this:

The first version printed:

The second version printed:

Maybe I misunderstood the orginal problem.

Changed out the for loop for an xargs. It's a tad shorter, and a tad cleaner.

Recursively replace a string in files with lines matching string. Lines with the string "group name" will have the first > character replaced while other > characters on other lines will be ignored.
