g'day I've been noodling around with the extra-character-bash-prompt-problem. It appears to manifest itself (for me at least) when I have title-bar info in my prompt, e.g.
% PS1='\[\e]0;\u\a\]% ' % echo $BASH<tab> $BASH $BASH_COMMAND $BASH_SUBSHELL $BASH_ARGC $BASH_LINENO $BASH_VERSINFO $BASH_ARGV $BASH_SOURCE $BASH_VERSION % echo $BASHH What's more the tipping point seems to be at 8 characters: % PS1='\[\e]0;1234567\a\]% ' % echo $BASH<tab> $BASH $BASH_COMMAND $BASH_SUBSHELL $BASH_ARGC $BASH_LINENO $BASH_VERSINFO $BASH_ARGV $BASH_SOURCE $BASH_VERSION % echo $BASH vs % PS1='\[\e]0;12345678\a\]% ' % echo $BASH<tab> $BASH $BASH_COMMAND $BASH_SUBSHELL $BASH_ARGC $BASH_LINENO $BASH_VERSINFO $BASH_ARGV $BASH_SOURCE $BASH_VERSION % echo $BASHH My full prompt (in all its glory ;-) : [175] ~ ; PS1='\[\e]0;[EMAIL PROTECTED]:\w\a\e[1;34m\]: [\!] \W ; \[\e[0m\]' : [176] ~ ; echo $BASH<tab> $BASH $BASH_COMMAND $BASH_SUBSHELL $BASH_ARGC $BASH_LINENO $BASH_VERSINFO $BASH_ARGV $BASH_SOURCE $BASH_VERSION : [176] ~ ; echo $BASHASH And removing the title-bar cruft: : [176] ~ ; PS1='\[\e[1;34m\]: [\!] \W ; \[\e[0m\]' : [177] ~ ; echo $BASH<tab> $BASH $BASH_COMMAND $BASH_SUBSHELL $BASH_ARGC $BASH_LINENO $BASH_VERSINFO $BASH_ARGV $BASH_SOURCE $BASH_VERSION : [177] ~ ; echo $BASH Perfect! I'm hoping this might trigger some insight in the clever buggers that maintain bash/readline.
