Hello, Thanks for the nice tool! I encountered a minor problem when using it in GNU parted when I ran "make >& log &". It caused the build to hang. Here's a stand-alone demo: Before the fix, it hangs: $ touch x.1; po4a-updatepo -f man -m x.1 -p x.pot >& log & [6] 1383 $ [6] + suspended (tty output) po4a-updatepo -f man -m x.1 -p x.pot >&log With the following patch, it completes as you would expect: 2007-02-14 Jim Meyering <jim(a)meyering.net&gt; Don't hang when running in background with redirected stdout. * lib/Locale/Po4a/Common.pm (BEGIN): Don't try to determine output terminal size when STDOUT is not a terminal.
