That works for regular output. However, some programs also emit error messages onto stderr. The above command will *not* redirect error messages into less, so they might mess up the pagination. To get error messages piped through less, use
command 2>&1 | less
dude! i've been trying to do that for months. tahnks!
as an aside, did /p in DOS redirect stderr, too? it's been so long
...
slash-p is specific to the dir command. DOS also has more.
I'm more familiar with OS/2 where one has to redirect stderr as in the example above. I believe that's also true on Windwoes.
I suppose for completeness we should mention tee.
tee writes its stdin to a file (which you name on the commandline) and to stdout. It's useful for keeping a record of events.
$ apt-get -b source kernel-image-2.6.6-1-386 2>&1 | tee building-kernels
We've also mentioned redirection. These two are different: $ apt-get -b source kernel-image-2.6.6-1-386 >one 2>&1 $ apt-get -b source kernel-image-2.6.6-1-386 2>&1 >one
This can be handy too:: $ apt-get -b source kernel-image-2.6.6-1-386 >one 2>two
and there's always this:
$ apt-get -b source kernel-image-2.6.6-1-386 >>one 2>>two
I'll leave you to RTFM to discover what these do and whether I've made any mistakes:-)
