Since the site seems to interpret raw text as HTML, I can imagine that it would be possible to embed all sorts of nasties in here. In my opinion, anything entered on forums should be interpreted as raw text and displayed as such.

#!/bin/bash
if [ $1 ]
then
steps=$1
else
steps=1
fi
while [ $steps -gt 0 ]
do
cd ..
(( steps = steps – 1 ))
done
pwd

Then, I add the following line to my .bashrc:

alias up=”source upl”

Then, wherever I am, it’s simply a metter of typing “up” to just go up one level, or “up ” to step up of levels. So if I’m 8 levels doen in a massive source tree, typing “up 8″ will immediatley jump up 8 levels, and print the new directory where I am. In this way, I can roughly guess how many levels I need to step up, and fine tune if afterwards, if required.

While extremely noddy, this simple script saves so much hassle ,and I really think something like it should be standard in the Linux command shell.

mcd() { mkdir -p “$1″ && cd “$1″; }

the latter won’t have problems with spaces on the argument.

as for the cd alias, instead of defining several ones it might be better to use a function too:

..() {
local levels=$1
while ((levels > 0)); do
cd .. || break
let “levels–”
done
}

with this you’ll do “.. 3″ and it will go back three levels and you can use any number.

4) In TCSH, use bindkey to bind ‘Alt-p’ to pwd.

2) alias cd to pushd, and set the shell variables pushdtohome and pushdsilent. cd now behaves as usual but now if you type ‘dirs -v ‘ (alias this to d), you get a stack of all the directories you’ve been to. You can easily cd back to those by typing ‘cd =1/’ etc.

add the following alias to the .bash_profile and re-login…

If you put the alias(es) in ~/.bashrc, you can ’source ~/.bashrc’ to (a) apply the alias(es) immediately without logging out and back in, and (b) confirm that the alias(es) won’t break anything, which can be difficult to fix if you can’t log back in.

I’m not sure, but I believe you can also ’source ~/.bash_profile’.
