> up 4
go up 4 folders (=> "cd .." 4 times).
> up
goes up one folder, and you can repeat pressing ENTER to go up one more. Press anything else to drop back to the shell.
Could probably be "better" (e.g. no subshells), but works well for me.
I mapped 'cd' to 'c' in my bashrc, but while doing it I also mapped 'c' to execute 'ls' as the latter was basically muscle memory whenever I was using cd. The .bashrc function looks like this:
c() { builtin cd "$@" && ls; }
.. () {
local arg=${1:-1};
while [ $arg -gt 0 ]; do
builtin cd .. &> /dev/null;
arg=$(($arg - 1));
done;
} up() {
local ups="."
for((i=0;i<${1:-1};i++)); do
ups="${ups}/.."
done
builtin cd "$ups"
}Though yours looks much nicer ^^"
