I had run a program that resulted in many more lines of output than my current terminal window height. As a result, I could only see partial results...is there any way to get the full output?
I am using the bash shell.

1Please change the word "width" in your question title by the word "height". Your accepted answer does not correspond to your wording with "width".– CbhiheCommented Aug 6, 2015 at 20:21

You could send the output to a file:
$ your_command > /tmp/output.txt
You could then open up that file in any text editor and examine it at your leisure.
Or, you could pipe the output directly to a program such as less that is specifically designed as a text reader and can help you page through data when it is more than a screen-full:
$ your_command | less

Yes I am aware of redirection, but I was hoping if there is any way I could resuscitate my last output, fully without having to run the program again.– SayanCommented Jul 19, 2011 at 15:24

1@Sayan: You can only do that if you are running in some sort of terminal that keeps a buffer for you. If you use
tmux(or the olderscreen) you can set them to keep hefty scroll-back buffers so that you can browse and even search the output quite a ways back ... but you have to be running in one ahead of time you can't roll back time and capture output that's already come and gone.– CalebCommented Jul 19, 2011 at 21:05
You can use Shift+Page Up/Down to scroll the current output.
In addition to which shell you are using, we need to know which terminal app you are using, for instance Gnome-terminal, or Konsole are the 2 popular ones in Linux. As mentioned by another answerer, SHIFT+PAGEUP is a common keystroke to scroll back through previous screens of terminal output.
P.S. When you said "terminal window width" did you mean "terminal window height?"

- definitely looks like that "height" was meant instead of "width".– CbhiheCommented Aug 6, 2015 at 20:22
