Thats right.
You have to put the result in a file and then afterwards read the file.
ls uname -r > file.txt
I'm sorry, but that's misleading on at least two accounts. The first is
that redirection (> and so on) is a property of the shell, so it won't
work unless you pass the entire command to a shell with (typically) the
-c option. The second is that as linked by leledumbo earlier
http://wiki.lazarus.freepascal.org/Executing_External_Programs there are
specific facilities in the runtimes to do this sort of thing and they
don't, as a rule, involve temporary files.
If I had to go on, what's that -r supposed to be doing? Are you trying
to execute uname -r and in that case where does the ls come into it?
Perhaps what you're really trying to do is something like
ls /boot/vmlinux-`uname -r`
(note those backticks which are NOT standard quotes) in which case you'd
be better first getting the uname output and then using standard file
operations to get the properties you're interested in. Finally, Linux
(but not necessarily other unix implementations) puts version
information into /proc/version which is accessible as a standard file-
no external program required.
