>Environment:
FreeBSD 2.2.0 systems in general
>Description:
A return in a /bin/sh script should return the exit status of the preceeding
command. /bin/sh under FreeBSD 2.2.0-R does not - it returns 0. FreeBSD
2.1.x does not exhibit this problem.
This behavior breaks many /bin/sh scripts.
>How-To-Repeat:
Execute the following commands:
$ /bin/sh
$ f()
return 78
$ g()
{
f
return
}
$ h()
{
f
}
$ f ; echo $?
78 # this is the observed result - it is correct
$ g ; echo $?
0 # this is the observed result - it is wrong. we should see 78 here
$ h ; echo $?
78 # this is the observed result - it is correct
$ exit
