Redirect all output to a log file

When you build a program or execute a shell command, the messages are often outputted to both standard output and standard error. If you want to send all ‘printf’ to a log file, use the following command:

make > make.log 2>&1

“2>&1”  is the part that redirects standard error to standard out, allowing you to capture all messages.
