What are man pages?
'Man' in this context is short for 'manual'. Man pages are electronic reference manual pages for UNIX commands. You can display the man page for a command with the command man command. For example, use the command man man to display the manual page for the man command.

You can also search the manual pages by keyword with the command man -k keyword. To select a man page from a different section, use the command man -s section.

How dow I submit labs?
Students taking the RESOLVE sequence (CSE221, 222 and 321) may submit using the workbence, or by using the rcpp-submit command. Most other classes use the submit command. The general format of the submit command is submit class lab file1 [ file2 ... ]. Your instructor will tell you the class name to submit for. For example, students in a section of CSE360 submitting file1.s and file2.s for lab1 to c360aa would use the command submit c360aa lab1 file1.s file2.s. For more information, see the manual page for submit (man submit).

Note: The submit command will remove any previously submitted files for that lab. If you need to re-submit any file after you have already submitted a lab, you must re-submit all of the lab files.

Why am I getting host key warnings when using ssh to connect to stdsun.cse.ohio-state.edu?
Because stdsun.cse.ohio-state.edu is an alias for several hosts, as you connect to each one, the host key associated with stdsun will appear to change. If you are using a UNIX variant and have Perl installed, download the stdsun script from ftp.cse.ohio-state.edu, in /usr/local/bin/stdsun. You should then be able to connect using stdsun -l. Be sure to edit the script and provide the location of the perl executable.
