Subject:   -24- How can I extract a single file from an 'inst'
                subsystem?

  Under IRIX 5.2 and earlier, you need to be clever. 'inst' guru Paul
  Jackson <pj@sgi.com> reveals all:

  - Find the subsystem in which the file lives, as described in the
    previous question. For this example we'll extract /sbin/ed, which
    lives in eoe1.sw.unix.

  - Follow the bouncing prompt:

    > su
    > cd /usr/tmp
    > mkdir -p tmproot/var/inst
    > inst -f /CDROM/dist/eoe1 -r /usr/tmp/tmproot
    > Inst> keep *
    > Inst> install eoe1.sw.unix
    > Inst> go
    > Inst> q
    > ls -l /usr/tmp/tmproot/sbin/ed
    -rwxr-xr-x    1 root     sys        75480 May 24 13:57 /usr/tmp/tmproot/sbin/ed

  - Move your file somwhere else and 'rm -r /usr/tmp/tmproot'.

  - That was under IRIX 5.x. Under IRIX 4.0.x or earlier, use
    '/usr/tmp/tmproot/usr/lib/inst' for a temporary inst directory
    instead of '/usr/tmp/tmproot/var/inst'.

  In IRIX 5.3, inst's '-Y' flag allows you to install a single file. See
  inst(1M) for more.
