Without having access to unix - looks to me like it is logging into sqlplus via silent mode (user=system/password=manager) and suppressing output by redirecting it to /dev/null, yet accepting echo to terminal.
End result (if it works) it should just produce output (of script or character input - whatever follows) to terminal.
