Directories with "bin" in the name are used to hold programs. The /bin directory holds basic user programs, such as login, shells (BASH, TCSH, and ZSH), and file commands (
cp ,
mv ,
rm ,
ln , and so on). The /sbin directory holds specialized system programs for such tasks as file system management (
fsck ,
fdisk ,
mkfs ) and system operations like shutdown and startup (
init ). The /usr/bin directory holds program files designed for user tasks. The /usr/sbin directory holds user-related system operations, such as
useradd to add new users. The /lib directory holds all the libraries your system makes use of, including the main Linux library,
libc , and subdirectories such as modules, which holds all the current kernel modules.
