There are two places program output can go: "standard output" and
"standard error". 'cmd >file' only sends standard output to file;
standard error still gets displayed on the console. In a
Bourne-compatible shell (ash/bash/ksh/zsh), you can do 'cmd 2>file' to
send standard error (only) to file, 'cmd >&file' to send both standard
out and standard error to file, 'cmd 2>&1' to send standard error to
the same place as standard output, 'cmd 2>&1 |less' to send that
output through less, etc. csh/tcsh are less
