Package: bash Version: 5.2~rc2-2 Dear Maintainer,
I was seeing incorrect cursor behaviour when my PS1 prompt got long, and was surprised to learn that merely moving a space character from after a control sequence to before it fixed the problem. Based on the man page, I think I've used the "non-printing" escapes correctly. Try this in an 80-character-wide terminal: x159='' while [ "${#x159}" -lt 159 ]; do x159=x$x159; done PS1=$'\\[\x1b[0;33;40m\\]'$x159$'$\\[\x1b[0m\\] ' Then enter an ordinary character such as 't'. I see my cursor move up a line to the final 'x' before '$', instead of the expected position after the 't' I just entered. But I see no problem with this prompt: PS1=$'\\[\x1b[0;33;40m\\]'$x159$'$ \\[\x1b[0m\\]' I only moved the trailing space. It's outside the non-printing sequence delimited by \[ and \] in both cases, so I'd expect no difference except the colour of that cell. - Michael -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.18.0-4-amd64 (SMP w/32 CPU threads; PREEMPT) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages bash depends on: ii base-files 12.2 ii debianutils 5.7-0.3 ii libc6 2.34-7 ii libtinfo6 6.3+20220423-2 Versions of packages bash recommends: pn bash-completion <none> Versions of packages bash suggests: pn bash-doc <none> -- no debconf information
