Unix based operating systems like Linux offer a unique approach to join two discrete commands, and generate a new command using the concept of pipe(lines). For example, consider command1|command2. Here, whatever output is generated by the first command becomes the standard input for the second command.
I'd like to pipe the output of ssh to a different command. For example:
ssh myserver cat remote-file | diff local-file -
The problem is that myserver asks for a password, but I can't enter it. (For some reason, public-key authentication is not available on the server. I can't change this.) I get the "Password:" prompt, but the keys I type are echoed, and not passed to ssh.
If If I understand what you are doing, you're trying to send input.mkv to a named pipe, use the named pipe for an input for x264, output to output.2641. mkfifo pipe.y4m2. mpv input.mkv --vd-lavc-o=strict=-1 ..... -o pipe.y4m3. x264 pipe.y4m --profile high --preset slow....--output output.264Why are you doing all that?
I'm trying to export the output of the "top" command (unix) with PHP. Invoking and reading the command/output is pretty simple using the "exex" function but the question is: is the "top" command output (order, names, etc.) always the same? Or is it related to the distribution I'm using?
Is there any way to parse these information "generally" on UNIX systems?
