Simple ksh question

Jason Berendsen — Mon, 18 Nov 2002 14:28:42 GMT

I am opening a file and reading it in with the following two lines:
exec 3< ${DIR}/extract.tmp
while read -u3 LINE

Unfortunately, I can't remember how to close this file descriptor. Does anyone know how?

Thanks,

Jason

The man page for ksh states-

exec 3<&-

should work.

hi,

Perhaps "exec 3<&-"

It should closed when the process closed. You can also close it by redirecting &- to it.

Try executing someting in the current shell like:
. /dev/null 3<&-
