How does a script figure out where it is being run from?
In Bash you can use this bit of ugliness:
# Find where we are installed; not linked to
SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a
symlink
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
SOURCE="$(readlink "$SOURCE")"
[[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative
symlink, we need to resolve it relative to the path where the symlink file was
located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
export DOTDIR=$DIR
Is there a way to do this in fish? Hopefully in a more straight forward way.
