>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.
