The "where am I" boilerplate that every nontrivial bash script needs. Resolves symlinks correctly with realpath, falls back gracefully if realpath is missing.
Bash
# Standard form — works for direct invocation and `bash script.sh`.
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
# Symlink-resolving variant (use this if your script may be symlinked):
SCRIPT_DIR="$(cd "$(dirname "$(readlink -f "${BASH_SOURCE[0]}")")" && pwd)"
# Or with realpath (cleaner if you have GNU coreutils):
SCRIPT_DIR="$(dirname "$(realpath "${BASH_SOURCE[0]}")")"
echo "Script lives at: $SCRIPT_DIR"
# Source a sibling file relative to this script
