tmux prints long commands to beginning of same line without line break

Question

When typing a long command in tmux instead of printing to the next line the end of the command shows up at the beginning of the same line.

So instead of user@computer:~$ aaaaaaaaaaa aaaaa this happens aaaaacomputer:~$ aaaaaaaaaaa

Using the standard terminal everything is fine.

See [Wooledge BashFAQ 53](http://mywiki.wooledge.org/BashFAQ/053), "I have a fancy prompt with colors, and now bash doesn't seem to know how wide my terminal is. Lines wrap around incorrectly." — that other guy, Feb 14 '18 at 22:02

If you have unescaped characters in your PS1 variable it might not wrap lines correctly.

Try

export PS1="\u@\h-\\$\[$(tput sgr0)\]"

If that fixes your problem you need to update your .bashrc file.

The answer might be the content of your TERM variable. What's the answer to

echo $TERM

?

Get the value of TERM before starting tmux and compare it with the value withing tmux! Try setting it to some other value like vt100 or xterm with

export TERM=vt100

or

export TERM=xterm
