Subject: Re: File size (shortest possible solution)  + don't touch
Date: Mon, 09 Aug 2004 14:14:40 -0700	[thread overview]
Message-ID: <4117E940.1030707@bcgreen.com> (raw)
In-Reply-To: <200408081725.13489.aroop@poornam.com>

the shortest possible:
       ` > somefile `
(( redirect the output of no command at all to somefile ))

Although not necessary, I'll often go
       ` true > somefile `
True does nothing other than return success. The reason why
I like using it is that it makes a placeholder so that a reader
knows that something (or rather explicitly nothing) is happening.


`Touch` doesn't work.. If the file already exists, it will simply
change the last mod-time. without altering the contents

The original purpose of touch (I think) was to convince make(1) that
something needed to be done.
