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 }

Create a directory called "dirname" and navigate into it.

if you cd into a directory then cd into another directory somewhere else then you run the cd - command you will go to the previous directory you was in!! To go back to the other directory just run it again. So if you are working in 2 different directories then this is the perfect command for you.

Somehow, i prefer forcing to rm interactively to accidently rm'ing everything...

the f is for file and - stdout, This way little shorter. I Like copy-directory function It does the job but looks like SH**, and this doesn't understand folders with whitespaces and can only handle full path, but otherwise fine, function copy-directory () { ; FrDir="$(echo $1 | sed 's:/: :g' | awk '/ / {print $NF}')" ; SiZe="$(du -sb $1 | awk '{print $1}')" ; (cd $1 ; cd .. ; tar c $FrDir/ )|pv -s $SiZe|(cd $2 ; tar x ) ; } Show Sample Output

Useful to quickly get back to the Windows root directory of the current drive from a sub-directory within that drive. Works also without space between 'cd' and backslash: 'cd\' or 'cd \' have the same effect Show Sample Output
