Plz guide me taht what does the following commands means

chmod 751 file chmod u=rwx,g=rx,o=x file

Instead of writing +r+w+x can we give number to change the filer permission. Plz enloght on it. Any site to learn in detail about this way to give number instead to write alphabets.

Thanks ain advance.

4 =read
2 = write
1 = execute

Add them up to get the rwx that you're looking for. Put them in the set of 3 to get the file permissions for owner, group, world.

"benjithegreat98" it is an interesting site. Plz also any other site for learning Linux commands .like rm,cat,df ,makdir etc etc.

I found that using google. Try searching there for beginners guides or something like that. Also when you are on the command line you can type "man rm" or "man cat" or man whatever. It is the manual for commands.
