Renaming the Executable File

It is inconvenient to have the result of every compilation in a file called a.out. If such a file already exists, it is overwritten. You can avoid this in either of the two following ways:

•Change the name of a.out after each compilation with the mv command:

hostname% mv a.out temp

•Use the compiler –ooption to name the output executable file. This example places the executable code in the file temp:

hostname% pc –o temp temp.p
