What is the most useful script you've written for everyday life? [closed]

Answer 1

A bash script called up so that if I'm in /a/very/deeply/nested/path/somewhere and I want to go "up" N directories, I can type up N:

#!/bin/bash
LIMIT=$1
P=$PWD
for ((i=1; i <= LIMIT; i++))
do
    P=$P/..
done
cd $P

For example:

/a/very/deeply/nested/path/somewhere> up 4
/a/very> 

NB by gmatt:

Working off the great work above, it can be extended to a back function by placing the following into your bashrc:

function up( )
{
LIMIT=$1
P=$PWD
for ((i=1; i <= LIMIT; i++))
do
    P=$P/..
done
cd $P
export MPWD=$P
}

function back( )
{
LIMIT=$1
P=$MPWD
for ((i=1; i <= LIMIT; i++))
do
    P=${P%/..}
done
cd $P
export MPWD=$P
}
