This little command (function) shows the CSV header fields (which are field names separated by commas) as an ordered list, clearly showing the fields and their order.

This command will grep the entire directory looking for any files containing the list of files. This is useful for cleaning out your project of old static files that are no longer in use. Also ignores .svn directories for accurate counts. Replace 'static/images/' with the directory containing the files you want to search for.

change ":" in path for new line and associate word path to var $PATH

This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line.

When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc.

Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current.

Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists

I've had this as mute.sh in my ~/bin/ for some time.

Adjust the

part for password length.

I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.

If you want a password length longer than 6, changing the -c6 to read -c8 will give you 8 random characters instead of 6. To end up with a line-feed, use this with echo:

# echo `< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6`

Scans the file once to build a list of line numbers that contain non-printable characters

Scans the file again, passing those line numbers to sed as two commands to print the line number and the line itself. Also passes the output through a tr to replace the characters with a ?

queries local memcached for stats, calculates hit/get ratio and prints it out.

Find random strings within /dev/urandom. Using grep filter to just Alphanumeric characters, and then print the first 30 and remove all the line feeds.

This works in bash and zsh.

You may also want to alias it, if you need to look at it often...

"\$PATH" to make sure to look at your current $PATH

If the file content is :

-

Blah blah blah

ABC

hello blah blah blah

bloh bloh bloh

DEF

Bah bah bah

-

You'll get:

-

ABC

hello blah blah blah

bloh bloh bloh

DEF

Reads psuedorandom bytes from /dev/urandom, filtering out non-printable ones. Other character classes can be used, such as [:alpha:], [:digit:] and [:alnum:]. To get a string of 10 lowercase letters:
