I've found one way so far: less +G filename, but it scrolls up line-by-line only with ↑.
What's a more powerful less usage which provides scrolling by page, backward pattern search, and so on?
Under a UNIX shell, how can I get a similar effect to the watch command, but with paging so that I can scroll around in the output if it takes up more than one screen?
In other words, I want a program that is to watch what less is to cat.
As an example, lets say I wanted to watch the output of qstat, I could use
watch qstat
to watch the output of qstat, but this can only shows the first screenful.
With a paging version of watch, I would be able to move around in the output as it is still continuously updated by watch. Is there any way to do this at the moment with existing utilities?
The question is based on this answer.
How can you set the -R in your LESS environment variable?
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?
When I have dircolors defined life is full of... color.
When I pipe ls through less to scroll around I lose the colors.
Any suggestions?
