Setting gcc Alias

In this course you need to compile code using gcc and a set of options. Instead of having to type those options every time, linux allows you to create an alias. The steps to create an alias are:

• Go to your home directory in grace. Remember that executing cd will take you to your home directory.
• In your home directory open (or create if it does not exist) a file called .aliases  (the filename has a period at the beginning.)
• Add the following line to the .aliases file and make sure you add a blank line after it.

                  alias gcc "gcc -ansi -Wall -g -O0 -Wwrite-strings -Wshadow -pedantic-errors -fstack-protector-all -Wextra"
                

• Log out and then log on again.
• You can verify the alias has been set correctly if you execute alias gcc and you see the following:

                  gcc -ansi -Wall -g -O0 -Wwrite-strings -Wshadow -pedantic-errors -fstack-protector-all -Wextra
              

• If you have problems you can also cut and paste the command from the file gcc_aliases_info.txt that will your find in the info directory of the grace public directory.
