I wanted to be really able to explain to a fair amount of detail how does the program :command:`ls` actually work right from the moment you type the command name and hit ENTER. What goes on in user space and and in kernel space? This is my attempt and what I have learned so far on Linux (Fedora 19, 3.x kernel).
How does the shell find the location of 'ls' ?

| # Backup all databases to separate archives. | |
| # 1. Each table is dumped into separate *.sql file. | |
| # 2. Each view is dumped into separate file with DEFINER=CURRENT_USER. | |
| # 3. All routines are dumped into routines-dbname.sql, | |
| # 4. All files are added to archive dbname.7z, compressed with 7-zip, max compression. | |
| # | |
| # Usage: mysqlback.sh /output/directory | |
