UNIX Permissions - table

Unix/Linux Permissions:

Here is the list of values and what they stand for in unix folder/directory permissions.Basically it is a simple you can count the value by using octa decimal binary numbers 421 :

See below image 

Value 0 directory listing is 000 = 0+0+0 
Value 1 directory listing is 001 = 0+0+1
Value 2 directory listing is 020 = 0+0+0  

This is where they gain their permission from :

so simple chmod 1 will give execute only permision on file/folder
so simple chmod 2 will give write only permision on file/folder
so simple chmod 3 will write & execute permision on file/folder

chmod 775 test.txt >> this mean 7 for 

UNIX Permissions
