[PATCH] Eliminate redirection to stdout and stderr when quiet option is available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This follows an earlier commit (7bd93c1) that eliminates the usage of
`>dev/null 2>&1` and friends when a `--quiet` option is available.
