Subject: grep /dev/null
Date: Wed, 02 Feb 2005 21:20:13 -0800 [thread overview]
Message-ID: <quack.20050202T2120.87lla66wz6@quack.cs.berkeley.edu> (raw)
I often when using `grep' type a regexp but forget to type a file
glob. This leads to slightly annoying behavior: it sits waiting
for input on stdin that never arrives. Once you realize that it's
not searching you have to kill it manually.
I think it would be useful if such grep invocations terminate
immediately. One easy way would be to always append " /dev/null
(i.e. grep-use-null-device) or " </dev/null". In fact, it might
be a good idea to add an optional flag to start-process so that
`compilation-start' can reliably pipe from null by default.
