From 6dc0c2f3384fe543a805922c6a314c7ad25a92fc Mon Sep 17 00:00:00 2001 From: Michał Górny Date: Sun, 18 Jul 2010 10:26:40 +0200 Subject: kbuild: Make the setlocalversion script POSIX-compliant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The 'source' builtin is a bash alias to the '.' (dot) builtin. While the former is supported only by bash, the latter is specified in POSIX and works fine with all POSIX-compliant shells I am aware of. The '$_' special parameter is specific to bash. It is partially supported in dash too but it always evaluates to the current script path (which causes the script to enter a loop recursively re-executing itself). This is why I have replaced the two occurences of '$_' with the explicit parameter. The 'local' builtin is another example of bash-specific code. Although it is supported by all POSIX-compliant shells I am aware of, it is not part of POSIX specification and thus the code should not rely on it assigning a specific value to the local variable. Moreover, the 'posh' shell has a limited version of 'local' builtin not supporting direct variable assignments. Thus, I have broken one of the 'local' declarations down into a (non-POSIX) 'local' declaration and a plain (POSIX-compliant) variable assignment.

For a quick example, navigate to the kernel compression options and get the help for bzip2. Doing so triggers a call to mvwprintw() with a string containing '%' and no extra arguments to fill in the specifier's value.
