Hi when I pressed the up arrow to see the previous command, it rewrote the current command from half.


21 /usr/local/sphinx/etc >  /usr/local/sphinx/bin/search --config /usr/local/sphinx/etc/sphinx-blog.conf php

and when I press the up arrow, it shows:

21 /usr/local/sphinx/etc >  /usr/local/sudo /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx-blog.conf --all

and "/usr/local/" before SUDO is from previous command. Do you know where the problem would be? Here is my prompt setting:

PS1="\# \e[32;1m\w > \e[0m "
  • and when i use BACKSPACE i will delete up to 21 /usr/local/sphinx/etc > /usr/local/ i'm not able to delete /usr/local/

  • Could you pleas execute read on the command line and then press the up-arrow? (you can exit read with ctrl+c) In theory, this should give ^[[A or \e[A (reps. ^[[B or \e[B for the down-arrow). Did you maybe configure bind for your arrow keys (eg. in the ~/.bash_profile)?

  • I tried it 18 ~ > /usr/local/read ^[[A^[[B^[[A^[[A^[[A^[[A^[[B^[[B^[[B

  • All of those characters appeared when you pressed the up arrow just once?? If so, then @Asmus is correct and something is wrong with your configuration.

I tried around and finally managed to find the error: you need to use even more escape sequences in your PS1 - this should work:

export PS1="\# \[\e[32;1m\]\w > \[\e[0m\]"

note the additional \[ and \] that wrap the colour escape sequences.
