cd up a number of levels

function ..(){ for ((j=${1:-1},i=0;i<j;i++));do builtin cd ..;done;}
Instead of typing "cd ../../.." you can type ".. 3". For extremely lazy typists, you can add this alias: alias ...=".. 2" ....=".. 3" - so now you can write just .... !!! NB the .. function needs to be "source"d or included in your startup scripts, perhaps .bashrc.

What Others Think

Nice idea! However, I'm not sure to get the reason why you use 'j=${1:-1}'. Is this parameter expansion trick useful? Is the new variable j useful? Please help me to understand :-)

That's quite fun. Alternatively (not equivalent but simplistically) : alias :="cd .." alias :.="cd ../.." alias ::="cd ../../.." alias ::.="cd ../../../.." # repeat until bored :-) -so now you can write just :: !!! :-)

{VAR:-VAL} means use $VAR if it's non-null, otherwise use VAL - think of it as a default.

I _like_ ':.' etc, what a hoot.

Hmmm php ate my '$' - that should have been: ${VAR:-VAL} means use $VAR if it's non-null, otherwise use VAL - think of it as a default.

it might help to add 'o=$PWD' and 'OLDPWD=$o' at the beginning and end in order for 'cd -' to work as expected

..() { cd "$(seq ${1:0} | sed '/.*/s,,../,' | tr -d '\n')"; } This way, you also keep your "cd -" working.

Actually make that: ..() { cd "$(seq ${1:-1} | sed '/.*/s,,../,' | tr -d '\n')"; }
