I want to read the contents of the file into the buffer and stdout it to the screen. I did this:screen -X readbuf /home/nitro/file|screen -X writebuf|cat /tmp/screen-exchangebut cat command showed me screen-exchange file with the previous result of readbuf command. If I do this commands separately - everything will be correct and I'll get the modified screen-exchange file.
How can I perform all three commands readbuf, writebuf and cat at once?
