The BSD /bin/sh is attempting to be POSIX.2-compliant. The POSIX.2 standard specifies that the file named by $ENV is sourced when the shell is invoked. Look at POSIX 1003.2-1992, section 3.5.3. Personally, I think $ENV should be processed only by interactive shells. ksh93 and bash-2.0 (when invoked as `sh') do it that way. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer Chet Ramey, Case Western Reserve University Internet: chet@po.CWRU.Edu
