du -hd1 (-h human readable, -d1 depth 1-level)

There are three levels of security associated with every directory and file.

• The first is the "owner".
• The next is the "group". You are assigned to the appropriate group when you get your account.
• The last level is "other" which is everyone on the system.

You can give or take away permission to read, write, or execute to any of user, group, or other. To see what permissions are set, use the command

ls -l

Here are two lines of example output

-rw-r--r-- 1 jsmit001 student 29607 Jun 16 09:34 tutor.vi

To back-up use the mysqldump command. For example:

mysqldump -Qq -hdb28.pair.com -uzrtch_2 -p zrtch_mykb > my-dump-mykb.sql

To upload use the mysql command. For example:

mysql -hDBSERVER -uzrtch_26 -p zrtch-espanaviva < dump-espanaviva-13OCT07.sql
