Looking through "git log --patch src/main.c", though, I find v0.5.3~42 (Do not clobber exit status in dotcmd., 2005-03-03), which appears to have been meant to take care of the following case: $ cat printstatus.sh echo $? $ false $ . ./printstatus.sh 1 I wonder if the following on top might help (imitating evalcmd)?
