If I have multiple log files open in several screens and I want to copy all useful traces to a single file, I initially copy them to the screen scrollback buffer file.
Doing ">" after selecting text will overwrite the buffer. How do I append selected text to the buffer file?
This question concerns screen commands in Linux.
Basically you've got four related operators to redirect input/output:
> will redirect your output and remove existing content (if possible). For example, this will overwrite existing contents of a file, but it won't clear the console contents:
command > mylog.log
>> will append your output to existing content, which is most likely the behavior you're looking for:
command >> mylog.log
< will read some source and treat it as input (stdin):
command < readfile.txt
| will redirect output to the input of the following command:
command | othercommand
