Is there a BASH version supporting POSIX job-control? We are currently using version 1.04.4 on our ULTRIX and SV3 boxes. It would be great if we could use the job-control facility we have under ULTRIX on System V too.

Job control that the shell gives you hooks into support that the kernel provides. If it isn't in the kernel, the shell can't do anything to give it to you. Job control isn't in the System V Release 3 kernel, so there's nothing you can do (other than upgrade your operating system). -- Tom Reingold tr@samadams.princeton.edu OR ...!princeton!samadams!tr "Warning: Do not drive with Auto-Shade in place.

It is possible to simulate 80% or more of BSD-style job control under
SysVRel3 (and previous) with judicious use of ptrace(2).

Well, there's not really any such thing as THE System V Release 3 kernel, as most vendors have dropped their own cruft into the one distributed by AT&T. At the least the SCO version has POSIX job control, so a version of bash should be able to be built providing job control on at least SCO's SVR3. Whether it has been or not, I don't know, but it should be possible. -- Brian L. Matthews blm@6sceng.UUCP

Well, *some* S5R3 ports *do* have job control; I think a number of the 386 ports have had - wait for it - POSIX job control added to them. I assume that's why he's asking, and why he specifically mentioned POSIX job control....

But Interactive's Sys V 3.2 Rel 2.2 DOES support POSIX-style job control and I'm interested in this Bash modifications, too, since I tried it to change the source but didn't succeed.

Not to worry; it's not *that* different. I have a version of bash with Posix job control; it has run on SCO, ISC, Ultrix 3.[01], AIX 3.1, SunOS 4.1, and HP-UX 7.0 successfully. It should be in the next release of bash, which will be 1.06. When that will be I cannot say.
