http://bugs.exim.org/show_bug.cgi?id=889 Summary: expr usage in exinext invalid on FreeBSD
Product: Exim
Version: 4.69
Platform: All
OS/Version: FreeBSD
Status: NEW
Severity: bug
Priority: low
Component: Unfiled
AssignedTo:
nigel@...
ReportedBy:
brentb@...
CC:
exim-dev@...
From the FreeBSD man pages:
Unless FreeBSD 4.x compatibility is enabled, this version of expr adheres
to the POSIX Utility Syntax Guidelines, which require that a leading
argument beginning with a minus sign be considered an option to the pro-
gram.
expr on FreeBSD requires '--' to come before any actual expression that uses
'-', or have expr compatibility mode be enabled by exporting EXPR_COMPAT=1.
Without this, exinext will fail. Including '--' appears to be harmless and not
affect expr operation on Linux.
