intro(8) intro(8)NAME intro - introduction to commands executed from the A/UX Startup shell DESCRIPTION The A/UX Startup shell (see StartupShell(8)) works like the Bourne shell, but it runs under the Macintosh Operating Sys- tem. Although it runs within a Macintosh partition, this shell honors the use of the files and directories from the A/UX root partition. For example, to list the contents of the A/UX directory /etc, the usual command syntax for ls is allowed ls options /etc The ability to access the files in an A/UX partition can be handy. For example, file system maintenance can be performed without an operable A/UX root file system (use fsck found in the StartupShell). Another advantage is that these commands allow you to exercise control over the boot process through modifications to startup files such as /etc/inittab prior to booting A/UX (use ed under A/UX Startup). Otherwise, such a change would require booting A/UX to make the changes, then rebooting (at least partially) in order to see the changes take effect. The StartupShell versions of A/UX commands that are avail- able include: cat chgrp chmod chown cp date dd dp ed esch fsck fsdb kconfig launch ln ls mkdir mkfs mknod mv od pname April, 1990 1

Notably, those commands that provide valuable administration functions such as esch (see esch(8) and autorecovery(8)) are described in the remaining pages of this section. 2 April, 1990
