FAQ: Common Linux Command Questions

What is the difference between sudo and su?

sudo lets you execute a single command with root privileges, while su switches your entire user session to another user (typically root). sudo is generally preferred as it:

• Doesn't reveal the root password
• Logs all commands executed
• Gives more granular control over who can run what commands
• Minimizes the time spent with elevated privileges

How do I find which process is using a specific port?

You can use the following command:

sudo lsof -i :port_number

Alternatively:

sudo netstat -tuln | grep port_number

How do I schedule tasks to run automatically?

Use the cron system:

1. Edit your crontab with crontab -e
2. Add entries in the format: minute hour day month weekday command

Example to run a script every day at 3 AM:

0 3 * * * /path/to/script.sh

How do I find which package provides a specific command?

On Debian/Ubuntu:

dpkg -S command_name

On Red Hat/CentOS:

yum provides */command_name

How do I check disk space usage on Linux?

Use the df command to check disk space:

df -h

To find the largest directories in the current location:

du -h --max-depth=1 | sort -hr
