erro de prompt de comando estranho

Question

Sempre que eu tiver dois prompts de comando abertos, sempre recebo este script depois de executar os comandos. Só para esclarecer os comandos executar e saída corretamente, mas após a saída antes do próximo prompt de comando eu recebo isso. Alguém sabe o que é e como resolvê-lo

N.B. se eu tiver mais de dois prompts de comando abertos, ele só aparecerá no segundo, não no terceiro ou no quarto, apenas no segundo

Eu resolvi o problema alterando o PS1 no meu arquivo .bashrc de

PS1='${debian_chroot:+($debian_chroot)}\[\e[1;4;32m\]\u@\h\[\e[00m\]\n\[\e[0;34m\]Date:\d | Time:\t\[\e[00m\]\n\[\e[2;33m\]Shell:\s | Version:\V\[\e[00m\]\n\[\e[4;1;31m\]CPU Usage $(echo print 'top -n 1 | tr -s " " | cut -d$" " -f10 | tail -n +8 | head -n -1 | paste -sd+ | bc'/ 'nproc' | python)% | Free Memory $(awk "/MemFree/{print \}" /proc/meminfo)\[\e[00m\]\n\[\e[4;35m\]Command History:\!\[\e[00m\] | \[\e[4;37m\]Command Number:\#\[\e[00m\]\n\[\e[1;33m\]{Directory:\w}\[\e[00m\]\n\[\e[1;2;32m\]I am ready for your commands master \$}-\[\e[00m\]\[\e[36m\]'

para

PS1='${debian_chroot:+($debian_chroot)}\[\e[1;4;32m\]\u@\h\[\e[00m\]\n\[\e[0;34m\]Date:\d | Time:\t\[\e[00m\]\n\[\e[2;33m\]Shell:\s | Version:\V\[\e[00m\]\n\[\e[4;1;31m\]CPU Usage $(echo print 'top -n 1 | tr -s " " | cut -d$" " -f10 | tail -n +8 | head -n -1 | paste -sd+ | bc'/ 'nproc' | python)% | Free Memory $(awk "/MemFree/{print \}" /proc/meminfo)\[\e[00m\]\n\[\e[4;35m\]Command History:\!\[\e[00m\] | \[\e[4;37m\]Command Number:\#\[\e[00m\]\n\[\e[1;33m\]{Directory:\w}\[\e[00m\]\n\[\e[1;2;32m\]I am ready for your commands master \$}-\[\e[00m\]\[\e[36m\]'

no entanto, se alguém pode me dizer o que estava errado com o primeiro PS1, então seria muito apreciado
