From 9debe63d10e476b96ff550d550df344a68b240e8 Mon Sep 17 00:00:00 2001 From: Shawn Pearce Date: Tue, 28 Feb 2006 21:43:33 -0500 Subject: Teach git-checkout-index to read filenames from stdin. Since git-checkout-index is often used from scripts which may have a stream of filenames they wish to checkout it is more convenient to use --stdin than xargs. On platforms where fork performance is currently sub-optimal and the length of a command line is limited (*cough* Cygwin *cough*) running a single git-checkout-index process for a large number of files beats spawning it multiple times from xargs. File names are still accepted on the command line if --stdin is not supplied. Nothing is performed if no files are supplied on the command line or by stdin. Signed-off-by: Shawn O.
