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. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
