8. Recursively give [a]ll users [r]ead permissions to files and e[X]ecute permissions to sub-directories within a directory: # chmod -R a+rX path/to/directory Conclusion On Unix and Linux systems, you would use the chmod utility to set permissions values on files and directories. You c...
Using chmod 777 <file-name> gives everyone rwx permissions, and it is generally not a good practice to give full powers to all the users in a system. The second case, I will leave you guys to figure out. Using umasks I will leave you guys with one more concept that you need to ...

Give [a]ll users rights to [r]ead and e[x]ecute: chmod a+rx path/to/file Give [o]thers (not in the file owner's group) the same rights as the [g]roup: chmod o=g path/to/file Remove all rights from [o]thers: chmod o= path/to/file Change permissions recursively giving [...
Read and Write without Execute is equal to 6. Read and Write and Execute is equal to 7. At this point, all you need to know is that your files should always have permissions of 644 or 755. (For most files, it doesn't matter if you give the executable permission or not. You won'...
2. Using symbolic values to add, remove the file permission u for user , g for group , o for others a for all ; r for read , w for write , x for execute , + , – & = for adding , removing and assigning r w x permissions. ...
+The plus means that we want to ADD the nextcoming permissions to the users on the line above. rwTells us what permissions we want to apply to these users: Read (R) and Write (W). This command would therefor give both the owner of the file, as well as the group it belongs to,...
