What do you do when a command floods your terminal with too much output?

I'm trying to solve a common annoyance: when SSH'd into remote servers I often do things that produce a lot more output than I'm expecting. For example, grepping a large log file with a pattern that turns out to be too general. As garbage churns by I sit there hitting ^C and wishing I'd remembered to pipe to less. My best idea so far has been to try to configure my shell to always page output, I asked another question about that. Other than that, I only have less-than-optimal solutions:

• Wait patiently for the output to finish
• Train myself to always pipe to less
• Get a bigger pipe and a faster box so output goes faster

What do you do?

Solution 1:

Try using screen. http://www.gnu.org/software/screen

You can switch to another shell and continue working on something else while the output completes and has the added advantage that the output will not be sent to your remote link if you are not watching it.

There is also support for buffer scrollback in screen, so you can page or search through the output when it is done.

If you are not using screen, ^C is not responding and you really need to terminate the job, you may want to try '~.' (the default ssh interrupt) to terminate the ssh session. You may need to hit enter before typing '~.'

Solution 2:

Other than the 3 suggestions you've mentioned, you an try ^Z, then just kill the process and fix it.
