I have just started developing in Unix environment and playing with screens and emacs.
My question might be preliminary but am unable to find an answer online.
I am able to create new windows in my screen ; however I am unable annotate them.
I know the command in Ctrl+a A; but how does one execute this on the keyboard?
Sorry if this questions seems silly; but is there way I can combine the Ctrl+a combination into a custom command?
Have you tried
screen -X title bla
yet?

I'm trying to learn Unix and can't figure out what ls -Rm does.
From the output of man ls, -R means "list subdirectories recursively", and -m means "fill width with a comma separated list of entries". I assume the / in your title was a typo, as it's not a valid option and will make the command not work at all.

a google search did not help me out so i'm hoping our community will...
i'm new to rstudio and while its easy to just press the up button to go back sequentially through r commands when the command you are looking for is just a few commands back, it's hard when the command is a while back.
I'm looking for something like ctrl-R in linux environments where you type a few letters and it completes your command based on your history.
is there something like this in rstudio?
You can try history()
For e.g
history(max.show = 50, reverse = F, pattern = "data.table::")
This will automatically open the commands used in the past .
You can search in your history in RStudio

I've seen ls -lahG reference in a few tutorials when ls -la seems to work just as well. I googled -lahG but I can't find any explanation.
Per ExplainShell:
-h provides human-readable output
-G avoids printing group names

I am using mitmproxy on Mac. I want to filter traffic by specifyc URL. The "intercept" function allows me to pause communication whenever filtered url is noticed. My question is - how can I filter traffic without pausing communication? I want it to continue to update without necessity to push "a" or "A".
You can press f to show only flows that match your criteria.
See https://docs.mitmproxy.org/stable/concepts-filters/ for the full filter syntax.

Why RStudio doesn't work after successful installation. When I'm opening RStudio (the up to data version V98.501) I see only a white desktop, the menu fields are completely paralized:
The only option is either Reload or Inspect.
How Can I fix this problem? It occurd when I was trying to switch from R 2.15 to R 3.0.2, getting Tools --> General Options-- > Choose R Version.
I tried to remove all and install again, it doesn't help at all.
On Windows, you can force RStudio to bind to a specific version of R by pressing and holding Ctrl when starting RStudio.
