Run shell command with input redirections from python 2.4?

Question

What I\'d like to achieve is the launch of the following shell command:

mysql -h hostAddress -u userName -p userPassword 
databaseName < fileName

Answer 1

As Andrey correctly noticed, the < redirection operator is interpreted by shell. Hence another possible solution:

import os
os.system("mysql -h " + ip + " -u " + mysqlUser + " " + dbName)

It works because os.system passes its argument to the shell.

Note that I assumed that all used variables come from a trusted source, otherwise you need to validate them in order to prevent arbitrary code execution. Also those variables should not contain whitespace (default IFS value) or shell special characters.
