There might be more but these were upto my knowledge
touch command is the most basic one which many people misunderstand. The touch command is used to modify timestamps on a file, but it actually gives the effect of creating a new file.
touch filename - will create an empty file touch -a filename - change the access time only touch -c filename - if the file does not exist, do not create it touch -d filename - update the access and modification times touch -m filename - change the modification time only touch -r - use the access and modification timestamp of file touch -t - creates a file using a specified time
it creates a file and also can modify the timestamps
Beyond software development, I ask everyone to try and use a Linux distro as their primary desktop os. Benefits range from simple performance improvements to much better respect for your privacy in comparison to windows.
Permission values are 1,2 and 4 as shown below and why not 3 after 1 and 2? 4 → read permission 2 → write permission 1 → execute permission This is basing on the power of two, starting from zero.
2*0 = 1 → execute permission 21 = 2 → write permission 2*2 = 4 → read permission Due to this logic, there is 4 and not 3.
This will help to remember permission values easily.

Exactly!
most of the people will not use these options & they won't bother about timestamps, so I haven't mentioned them previously.
Thanks for sharing this!
Very Informative!
A great one to get some high-level understanding.
Thank you, Ojus :)
Am glad you liked it.

Really a good article for beginners for those who don't know the basics of Linux, like me! Thank you very much for providing this article!!!
:-)
Thanks, glad to hear that.
File permissions have tripped up even the most seasoned user.
oh yes..
Amazing article 👍
Thank you so much :)
This is a staple starting guide for those who are getting into Linux like myself.
