The root directory (/) in Linux is the foundation of the file system hierarchy. Here’s a breakdown of its key directories and their purposes:
- /home: Contains user directories.
- /usr: Holds most programs and libraries.
- /var: Stores variable data like logs and temporary files.
- /tmp: Used for temporary files and data.
- /etc: Keeps system configuration files.
- /bin: Essential system binaries reside here.
- /sbin: System binaries for the root user.
- /lib: Libraries for programs.
- /lib64: 64-bit libraries for programs.
- /mnt: For mounting removable media.
- /opt: Optional software packages installation directory.
- /proc: Contains system process information.
- /sys: Holds hardware information.
You Should Know:
Here are some practical Linux commands to navigate and manage the root directory:
1. List Root Directory Contents:
ls /
2. Navigate to a Directory:
cd /home
3. View System Logs:
cat /var/log/syslog
4. Check Disk Usage:
df -h /
5. Find Configuration Files:
find /etc -name "*.conf"
6. Mount a Device:
sudo mount /dev/sdb1 /mnt
7. Check Running Processes:
ls /proc
8. View Hardware Information:
cat /sys/class/net/eth0/address
9. Create a Temporary File:
touch /tmp/testfile.txt
10. Install Software in /opt:
sudo tar -xzf software.tar.gz -C /opt
