One-liner: set variable to contain stderr or stdout (redirect error to out stream)
Use 2>&1.
Example: Firefox may complain that it has not all packages it needs, capture what it complains about:
> firefoxSays=$(firefox --version 2>&1 ) ; echo $firefoxSays
![[i]](http://www.thinkplexx.com/wp-includes/images/smilies/thinkplexx/set1/InfoX16.png)
REMARK: you can grep for particular problem, i.e. does Firefox complain about not having libdbus?:
> firefoxSays=$(firefox --version 2>&1 | grep libdbus ) ; echo $firefoxSays
