What you want here is the magic of shell redirection.

You can redirect whatever goes to the console using the > character:

somecommand > log.txt

Will write the normal output of the command into the log.txt file.


However, to make it more confusing, the output to the console contains not
only
normal output, but also error output. To redirect this too, use

somecommand 2>&1 >log.txt

An explaination for the curious.

The normal output is stream 1, the error is stream 2.


somecommand > file or somecommand 1>file

will redirect the normal output into the file

somecommand 2>file

will redirect the error outpuf in the file

somecommand 2>&1

Will redirect the eror output into the normal output

so

somecommand 2>&1 > file

redirects both into the file.


N.B. The ordering of the lines may not be quite the same as you see on the
console, as the error and output streams may be buffered.
