We have all heard of /usr/bin /usr/local/bin and so on. Do we know how and why they are organized?Let's get started
/bin - user utilities - cd ls cat bash cp pwd - all these are here. Did you know?
/sbin - s for system program and administration
ping mount reboot shutdown ifconfig - ring a bell?
/usr/bin - non-system programs -
awk base64 curl emacs find grep ssh php vim perl php python rake rails sed
/usr/sbin - system daemons(background processes) & system utilities only
chown chmod cron httpd sendmail sshd apachectl - sytem utilities that are user specific
/usr/local/bin - The programs installed over the base operating systems due to a dmg file installation or using a package manager might land up here.
Example: Lets say you install mysql it would be installed in /usr/local/mysql/bin. Similarly php would be installed in /usr/local/php
/bin and /sbin - commands provided by OS - /bin - consumers /sbin - system administrators
/usr/bin - utilities used by developers
/usr/sbin - utilities used by OS administrators
/usr/local/bin - compilers/executables softwares installed - php and mysql
/usr/local/sbin - administrative commands for softwares installed - Apache restart, mysql server start re-start
We all use cd, ls and many such commands in the macOS Terminal day in and day out. I am better than yesterday after I learnt this today. I know where to search my executables.
