FreeBSD quartz.ins.cwru.edu 5.0-CURRENT FreeBSD 5.0-CURRENT #3: Tue Jul  2 09:13:32 EDT 2002     chet@quartz.ins.cwru.edu:/usr/obj/usr/src/sys/CNS-OPTIPLEX  i386

>Description:
     There is a parsing problem with /bin/sh.  The attached script should not work without a backslash at the end of the first line, but sh accepts it nevertheless.

This faulty syntax is used in /usr/libexec/locate.mklocatedb
(/usr/src/usr.bin/locate/locate/mklocatedb.sh).
>How-To-Repeat:
quartz(2)# cat x1
awk '{print 12345}' </dev/null
        || exit 1
quartz(2)# ./sh ./x1
quartz(2)# /bin/bash ./x1
./x1: line 2: syntax error near unexpected token `||'
./x1: line 2: ` || exit 1'


>Fix:
The patch for mklocatedb.sh is obvious; lines 79 and 87.
