A brief lesson on redirecting output.
make depend 2> logfile.txt
This will redirect standard error to the file "logfile.txt".
make depend > logfile.txt
This will redirect standard output to the file "logfile.txt".
make depend > logfile.txt 2>&1
This will redirect both standard error and standard output to the file
"logfile.txt". Note that in this case, the "> logfile.txt" _must_ come before
the "2>&1".
Most programs send their error messages to standard error, but occasionally an
application may be programmed to send it's error messages to standard output
instead. Some non-error messages may also be useful in debugging an error as
well. As such, it is advisable to trap both the standard error as well as the
standard output.
