When it says "Invalid Directory Name"
get the ip address on your LAN Show Sample Output
It lists files and folder under dirname adding at the beginning of each line the file allocated size in blocks (-s). It also sorts output by file size (-S) from bigger to smaller. Actually the -t option in that precise position does not give any effect... (challenge: can you tell me why?) but of course gives to the ls command some salty taste! :)
Works at lest with .gz .bz2 .tar.gz .tar.bz2
I put this line in my ~/.bashrc file (which I source via ~/.bash_profile). Now, when I need to install a package, I typed *install* instead of the longer version.
Get colorful fortunes dictated by an ASCII cow. For full enjoyment you'll need to have color setup enabled for your terminal.
Prints the size of Directory in human readable format like KB MB or GB. If you want to see size each files and directories inside the directory use -a option as shown in second output and if you want a total sum then add -c option :) Show Sample Output

Thanks to the great grml team for this func!

some people on the net already use a cd(), but most of them break 'cd -' functionality, that is "go back where you have been previosly", or 'cd' which is "go back home". This cd() copes with that. Also when given a file name, go to the directory where this file is in. cd() { if [[ -n ${*} ]] then if [[ s${*}e == s-e ]] then builtin cd - elif [[ ! -d ${*} ]] then builtin cd "${*%/*}" else builtin cd "${*}" fi else builtin cd ~ fi ls -la }
