What is more tedious? Typing in 4 characters ‘DATE‘ and getting back the current date and time, or having to type in a series of intricate commands (susceptible to finger checks)? Yes, the string of commends can be saved as a script but then you still have to type in the name of the script on the terminal (more finger checks).

“38. host and dig Commands”

You explain what the ‘host’ command is used for. You don’t explain what the ‘dig’ command is used for.

“41. touch /forcefsck”

Maybe you should explain that the ‘touch’ command is used generally to create files/directories and then explain the specific ‘/forcefsck’ example.

This produces no output on my system.

Thanks @ quydo,
for your such valueable feedback.
All the commands are useful, at some point of time.

I think you should post commands which used frequently in daily work :D

For example command number 37 :D

Thanks for your useful tutorial ^_^

Run the ‘passwd username’ to command to reset current logged in user. Make sure you must be root user to perform such command.
