Explanation

When a user logs in to the system and the user’s login shell is a BASH shell, the commands in the /etc/profile file are executed. The /etc/profile.d/ directory serves as a storage location for scripts administrators may use to set additional system-wide variables. It is recommended you set the environment variables via scripts contained in /etc/profile.d/ rather than editing the /etc/profile file directly. for i in /etc/profile.d/*.sh ; do if [ -r "$i" ]; then if [ "${-#*i}" != "$-" ]; then . "$i" >/dev/null This code means “if there is a file that ends in .sh in the /etc/profile directory and it is readable, source (run) the contents of this file in the current shell.”
