I find it ugly & sexy at the same time isn't it ?

Some other notable dates that have passed:

rot13 maps a..mn..z (A..MN..Z) to n..za..m (n..za..m) and so does this alias.

create a short alias for 'ls' with multi-column (-C), file type syntax additions (slashes after directories, @ for symlinks, etc... (-F), long format (-l), including hidden directories (all ./, ../, .svn, etc) (-a), show file-system blocks actually in use (-s), human readable file sizes (-h)

Searches /var/log/secure for smtp connections then lists these by number of connections made and hosts.

Searches the /var/log/secure log file for Failed and/or invalid user log in attempts.

Not so much handy by itself, but very nice in shell scripts.

This makes you a handy ncurses based checklist. Much like terminal installers, just use the arrow keys and hit 'Space' to adjust the selections. Returns all selected tags as strings, with no newline at the end. So, your output will be something like:

"one" "two" "three" "four" "etc"

For those who prefer bash expansion over gratuitious typing:

Things to note:

The height must includes the outer border and padding: add 7 to however many items you want to show up at the same time.

If the status is 1, it will be selected by default. anything else, will be deselected.

This command will tell you the 20 biggest directories starting from your working directory and skips directories on other filesystems. Useful for resolving disk space issues.

If you need to print some portion of a huge file, let's say you want to print from line 200 to 300, you can use this command to print the line from LINE1 to LINE2 of file FILE.

The pinfo package makes info pages much more bearable. It is a ncurses-based POSIX utility for viewing info and man pages using lynx style keyboard shortcuts and rendering. Links are highlighted blue, the current location of your cursor is red. Navigating and searching are easy. Worth the install.

By time thumbnail images in ~/thumbnails take up too much space, this command will help deleting old ones.

Find options explained:

-type f : find files only, not directories

-atime +30 : last accessed more than 30 days ago

An improved version of http://www.commandlinefu.com/commands/view/1772/simple-countdown-from-a-given-date that uses Perl to pretty-print the output. Note that the GNU-style '--no-title' option has been replaced by its one-letter counterpart '-t'.

If (when) you forget to "svn rm" files from your repository, use this to let your repository know you want those files gone. Of course this works with adding and reverting too.

Extremely useful to maintain backups if you're using Dropbox. This mirrors the entire directory structure and places symlinks in each to the original file. Instead of copying over the data again to the ~/Dropbox folder creating a symbolic link tree is much more sensible in terms of space usage.

This has to be supplemented by another script that removes dead symlinks in the Dropbox folder which point to files that have been moved/removed.

And then removing empty directories

**Actually after some finding I found lndir which creates symbolic trees but it wasn't in the Arch repos so.. ;)

Nice interface for an info page.

A great way of viewing some man page while using gnome.

This requires that your sudo not prompt for a password, as sftp cannot allocate the terminal necessary to ask.

Might be more useful if you were able to print it in Days HH:MM:SS format as:

But I'm not exactly sure how to replace the 234234 with the output of the countdown time. (Having some problems with nested quoting/command substitution). Help would be appreciated :)
