I know if I execute a command like '
ls' and I want the output in a file, I can type '
ls > filename'. What do I type if I want
both a saved version
and the output of ls on the screen at the same time. I'm using '
ls' as an example, really I want to execute '
aptitude' and at the same time save the output to a file and see the output on the screen. I'm a debian user. Thanks in advance for any help.
