UNIX Quick Command Reference

This was shamelessly stolen from the University of Singapore on Dec. 21, 1992 and credit/blame for this should probably be given to Dr Tan Tin Wee, Department of Biochemistry, University of Singapore.


Here is a list of popular commands and software systems available on the CEC UNIX systems. To get the manual page for a command, try `man command_name'. To get the help on that command, if any, try `help topic_name'.
