Frequently I get odd results when using Emacs mode command line editing in Bash.1) Sometimes after scrolling back in my history, the first 9 characters of the line will remain in place, and the beginning-of-line position moves 9 characters to the right. So, for example, if I scrolled past an entry that started with "awk '{if ($1 > 100 ) {print $2}', when pressing Ctrl-U, the cursor will be positioned after 'awk '{if '. It only seems to be affected by certain longer entries in the history. 2) When typing a line that's longer than my terminal is wide (including the command prompt), the cursor will return to the beginning of the line, but it will not line feed, so it starts overwriting the text that is already there. If I make my terminal wider and press Ctrl-L, the line can be edited normally, until it needs to wrap again, then the problem repeats. Once I exit screen, command line editing in Bash works properly. The Emacs editor itself seems to have no issues, nor does vim. I'm using PuTTy on Windows. $TERM is 'xterm'. I've tried substituting 'vt100' but it didn't fix the problem. Screen v4.09.00 on Centos7, Bash version is 4.2.46(2).
What is your $PS1 ?
