Why console prompt behaviour changed when added new color escape sequences to $PS1 in /etc/bashrc?
Issue
- Changed the $PS1 parameter in /etc/bashrc as follows:
[ "$PS1" = "\\s-\\v\\\$ " ] && PS1="\\033[1;33mUAT\\033[0m-[\u@\h \W]\\$ "
-
After making above changes the behaviour of console prompt got changed. When up key is pressed to view history, it prints random characters at the prompt.
-
For eg:
Executed following commands:
UAT-[root@localhost ~]# yum --nogpgcheck info /home/soft/oracle-validated-1.0.0-24.el5.x86_64.rpm
and
UAT-[root@localhost ~]# ls
Then pressing up key prints weird characters as follows:
UAT-[root@localhost ~]# yum --nops -ef|more
