comment Unix sort out of memory
@roaima, there's nothing in the OP's question that specifies that /bigdisk is not at least in part backed by RAM. drevicko makes it clear that his/her answer's premise is that /bigdisk is RAM-backed. It will certainly help people with the same problem even if not the OP, so doesn't deserve a downvote I would say.

comment sed to delete lines using multiple search string
@Peter.O, GNU sed's --posix is to tell it to be more POSIX conformant. It's not telling it to report an error on any non-POSIX code you throw at it. It would not make GNU sed more POSIX conformant to report an error when you give it that non-standard {xxx} code.

@cuonglm {command} is not required to report an error by POSIX. It's just that a POSIX script must not use it as the behaviour is not specified there. Where GNU sed is not conformant even with --posix is that it doesn't accept ; in label names.

@cuonglm, no. AFAICT, ;} above is not POSIX but I don't know of any modern sed implementation where that fails.
