Tmux viewport caused by multiple concurrent sessions When attaching to the same tmux sessions from multiple computers using ssh and `tmux attach`, my screen looks like: ------------------------- $> |........ |........ |........ |........ |........ -----------------........ ......................... ......................... I was wondering if there is a command to get rid of the viewport

Probably the width/height (colums/rows) of the "original" terminal form which you launched te tmux session is lower than that of the terminal you're attacching from. Personally I don't use tmux, but that happens to me with `screen` when I launch from a 80x25 terminal and then I attach from another terminal with 80x50 columns/rows.
