Sure.
command 2>/some/file
The `2>' causes descriptor 2 (stderr) to be redirected. In general,
you can use `N</some/file' and `N>/another/file' for any value of N.
Also:
command </some/file is equivalent to command 0</some/file
command >/some/file is equivalent to command 1>/some/file
command &>/some/file is equivalent to command 1>/some/file 2>&1
The last form redirects both stdout and stderr to the same file (the
notation `2>&1' means `redirect descriptor 2 to the same place as
descriptor 1).
See the bash(1) manpage for more details of redirection. Also see the
dup2(2) manpage for details of the dup2() system call (which is used
to implement I/O redirection).
