CHMOD

sudo chmod u=rwx file1.txt sudo chmod 755 file2.txt Is used to give permission and we can do it with octal or letter format. r = Read permission w = Write permission x = Execute Permission In Octal. 0 : No permission 4 : Read 1 : Execution 5 : Read and Execute 2 : Write 6 : Read and Write 3 : Execute and Write 7 : Read , Write and Execute

2 CHMOD - R

The minus R is used to look inside a subdirectory for example. sudo chmod -R 775 ./one/file3.txt You can also use the asterisk (*) to change the permission for the entire directory

3 CHMOD --version

This parameter is used to see the version of chmod that we have installed.chmod --version

4 CHMOD --help

This parameter is used to see the help of everything you can do, such as chmod -R. chmod --help

5 CHMOD -f

This parameter is used to mute error messages. For example. I am going to put directory one and I am going to put a file that does not exist. Without the -f : sudo chmod 775 ./one/file4.txt With the -f : sudo chmod 775 -f ./one/file4.txt

Thank you for your attention
