Vim: Moving around

You can save a lot of time when navigating through text by using appropriate movement commands. In most cases the cursor keys are not the best choice.

Here are some basic movement commands that may help you acquire a taste for more:

e       Move to the end of a word.

w Move forward to the beginning of a word.

damc-dev

#!/bin/sh
function toLowerCase {
    local word=$1
    local lowercaseWord="$(tr '[:upper:]' '[:lower:]' <<< "$word")"
    echo "${lowercaseWord}"
}
lowerCaseWord="$(toLowerCase $1)"
echo "$lowerCaseWord"
