CSE 80 -- Lecture 1 -- Jan 7
This lecture covered class preliminaries -- the
first (and only) paper handout, accounts, etc.
Note: the manual page hyperlinks found in this and
future class Web pages are to a Web server running on a Web server
which, while running Solaris, does not have exactly the same software
installed on it as the uAPE machines; furthermore, the search path for
commands differ from the default for the uAPE machines, so the manual
page displayed for the ls program,
for example, is the GNU version of the ls program, not the
one found in /usr/bin/ls. The uAPE lab machines does not
have the GNU version available at all. The hyperlinks are for your
convenience, since most things are identical, but when in doubt, type
in $ man ls at your shell prompt to be 100% sure. The GNU
software typically implements all of the POSIX standard flags and
include extra ones (esp the longname versions introduced with the
double dash).
The topics covered are:
I mentioned in class that the output of $ ls and $ ls |
more (or even $ ls | cat look different. Why?
I mentioned in class that the more command is also special,
since it reads the terminal for a prompt. How does it do that?
