Can we execute system commands under MySQL prompt? Yes, we can.
We can do it by adding \! (a backslash, a exclamation mark and a white space) before the shell command. For example, if you want to know present working directory, you can do it like this:
mysql> \! pwd
/root
Don't forget to add these characters before shell commands:
- A backslash (\)
- A exclamation mark (!)
- A white space ( )
