Suppress output of loud commands you don't want to hear from

Suppresses all output to /dev/null. This could be expanded to check for a -l command line option to log the stderr to a file maybe -l file or -l to log to default quietly.log. I'm finding that I use it more often than one would think.

Alternatives

There are 6 alternatives - vote for the best!

Terminal - Alternatives
quietly() { "$@" |&:; }
quietly() { "$@" > /dev/null 2>&1; }

This works even if there are spaces in any word in the command line.

Know a better way?

If you can do better, submit your command here.

What others think

less verbose to do it like >/dev/null 2>&1

Wow, that's a good idea. A few things, though.

You need to quote $* just in case the command has a space in it.

Shorten the redirects as TheMightyBuzzard says.

Shorten the name to something simple, maybe 'q' (too much typing otherwise :-)

function q () { "$*" > /dev/null 2>&1; };

Of course in bash, you don't need the keyword 'function'!

q() { "$*" > /dev/null 2>&1; };

fantastic, i have created 2 aliases for me. one for total silence, the other just redirects err to out for easy grepping ;)

function q () { $* 2>&1 ; }

function qq () { $* 2> /dev/null > /dev/null; }

PS: I do not think quotes are necessary or even good.

* without quotes fails, if there are spaces in the command or its arguments. $* with quotes "expands to a single word with the value of each parameter separated by the first character of the IFS special variable." (man bash). So it tries to run the whole command-line as a command name.

So, the only valid option here is "$@". It expands to a list of quoted words, just like the original.
