From 7f51f8bc2b9d0556f2fbe20056e8fc8839766c99 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Fri, 7 Jan 2011 00:00:38 +0100 Subject: [PATCH] alias: use run_command api to execute aliases On Windows, system() executes with cmd.exe instead of /bin/sh. This means that aliases currently has to be batch-scripts instead of bourne-scripts. On top of that, cmd.exe does not handle single quotes, which is what the code-path currently uses to handle arguments with spaces. To solve both problems in one go, use run_command_v_opt() to execute the alias. It already does the right thing prepend "sh -c " to the alias.
