A simple bash script to install and configure a few items that I aways use

install_softwares.sh

#!/usr/bin/env bash
# Don't forget to `chmod +x install_softwares.sh` before running this script.

# If not running under bash (e.g., invoked with `sh`), re-exec with bash
if [ -z "${BASH_VERSION:-}" ]; then
  exec bash "$0" "$@"
fi
