This alternative either opens the current working directory by just issuing the open function in the commandline. Or you can specify what directory you would like to open.

Example: open /cygdrive/c/Windows

When no option is specified it will open the current working directory

Automatically drops mount points that have non-numeric sizes (e.g. /proc). Tested in bash on Linux and AIX.

The expression $(( $RANDOM * 6 / 32767 + 1 )) generates a random number between 1 and 6, which is then inserted into the escape sequence \e[3_m to switch the foreground color of the terminal to either red, green, yellow, blue, purple or cyan.

The color can be reset using the escape sequence \e[0m.

The full list of colors can be found here: https://wiki.archlinux.org/index.php/Color_Bash_Prompt#List_of_colors_for_prompt_and_Bash

Use the command line to log into Dropbox. You have to replace me@yahoo.com with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag.

Batch resize all images to a width of 'X' pixels while maintaing the aspect ratio.

This makes uses of ImageMagick to make life easier.

It starts in the current working directory.

It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself).

It will print a failure message for every directory that isn't empty.

This command handles correctly directory names containing single or double quotes, spaces or newlines.

If you do not want only to remove all the ancestors, just use:

This command removes and then cvs removes all files in the current directory recursively.

use it to add a random boolean switch to your script

use it to stagger cronjob or to get a random number

increase the range by replacing 100 with your own max value

I don't like doing a massive sort on all the directory names just to get a small set of them. the above shows a sorted list of all directories over 1GB. use head as well if you want.

du's "-x" flag limits this to one file system. That's mostly useful when you run it on "/" but don't want "/proc" and "/dev" and so forth. Remember though that it will also exclude "/home" or "/var" if those are separate partitions.

the "-a" option is often useful too, for listing large files as well as large directories. Might be slower.

list the top 15 folders by decreasing size in MB

This commands queries the delicious api then runs the xml through xml2, grabs the urls cuts out the first two columns, passes through uniq to remove duplicates if any, and then goes into linkchecker who checks the links. the links go the blacklist in ~/.linkchecker/blacklist. please see the manual pages for further info peeps.

This allows you to search through your history using the up and down arrows ? i.e. type "cd /" and press the up arrow and you'll search through everything in your history that starts with "cd /".

Only requirement is bash shell. No functions needed.

this bash command sets it so that when you type "screen ", it searches your running screens, and present valid auto-complete choices. The output is .
