By using chmod command
for example chmod 777 <file name>
its for full permissionof the file


read =4
write =2
execute=1

user group other
7 7 7
4+2+1 4+2+1 4+2+1

r+w+e r+w+e r+w+e



other example


we give permission to user to full and give group and other
to only read and execute than


chmod 755 <file name>
