Unix help needed!
I have a few questions about Unix. Can you please help!
1.How do I create an alias that greps the password file for my username and returns my password file entry? Once I get the alias to work I want to be able to let a friend use it .So that he can use the alias to locate his password entry without having to make any changes to the alias.
2. When you normally execute the man command the output is display one page at a time. What man command option would you use if you did not want the output of the man command to be displayed by pages?
3. What effect do the redirection characters have on this string command? cat > hh < file
