[macos] How can I make directory writable?

How can I make a directory writable, from the OS X terminal?

chmod 777 <directory>

this not change all ,just one file

chmod -R a+w <directory>

this ok

Execute at Admin privilege using sudo in order to avoid permission denied (Unable to change file mode) error.

sudo chmod 777 <directory location>

• chmod +w <directory> or chmod a+w <directory> - Write permission for user, group and others

• chmod u+w <directory> - Write permission for user

• chmod g+w <directory> - Write permission for group

• chmod o+w <directory> - Write permission for others

chmod +w <directory>

To make the parent directory as well as all other sub-directories writable, just add -R

chmod -R a+w <directory>
