Ruby get return from system command (sox) -
i trying assign stats sox
command ruby variable. when using system
'true/false' depending on success of command. i've tried:
%x{ sox file -n stats }
this shows stats in console, returns empty string, so:
stat: 123 stat: 234 ""
i want obtain string contains stats. possible?
use ticks:
result = `sox file -n stats`
make sure sox doesn't output stderr. in such case redirect.
result = `sox file -n stats 2>&1`
edit ticks , %x{}
same. sorry. mixed system
. redirect need.
