While installing from binaries. The below always gives error when we execute from 'scripts' directory

[mysql@hostname ~]$ cd /mysql/product/5.6.12/scripts/
[mysql@hostname ~]$ . mysql_install_db --defaults-file=my.cnf

-bash: use: command not found

But the same works fine when I execute one step back from scripts directory

[mysql@hostname ~]$ scripts/mysql_install_db --defaults-file=my.cnf

Question: Why this happens ?

  • I guess it's expecting to be one dir up from scripts, when it's not then something goes wrong & it drops out of the mysql shell, then tries to execute the "use" (intended for the mysql interpreter) in the shell

  • Open the mysql_install_db file and go through the script - IIRC it's a text script file.

    It may work if you do ./mysql... ? Specify the path of the my.cnf if it's not in the scripts directory.

I think you have a mistake, you can't execute:

[mysql@hostname ~]$ . mysql_install_db --defaults-file=my.cnf

Because the correct line is:

[mysql@hostname ~]$ ./mysql_install_db --defaults-file=my.cnf

You don't have in PATH environtment variable the current directory ".".


The problem appears to be that you're trying to source the installation script by putting . (dot space) in front of the script name. This behaves differently from executing the script.

Prefix the mysql_install_db with a ./ instead:


When you execute it from the level above, you're not including the . (dot space), so it executes the script and works as you expect.
