Suppress warning output in bash

Question

``` mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql ``` I tried adding 2>/dev/null, &>/dev/null, etc, nothing seemed to suppress the warnings.

Accepted Answer

```
mysql_tzinfo_to_sql /usr/share/zoneinfo 2>/dev/null | mysql -u root mysql
```

The command that is producing the error output to STDERR is the first command, not the second one. Put the STDERR redirection before the pipe, and this should fix your problem.
