open can be used to open a file for reading or writing. In the "open" statement, the second parameter can be:

• a = append to the file
• r = read the file
• w = write (overwrite) to the file

If the file does not exist and "a" (append) or "w" (write) are used, the file will be created. If "r" is used or no operand is used, and the file does not exist, "No such file or directory" will probably be returned so you may want to first use touch to create the file if it does not exist.
