As far as I see from "man sh", the system's shell does not support PROMPT_DIRTRIM, so it's a bash feature. According to "man bash", its initialisation file is called ~/.bashrc. For example, if I put export PS1="\u@\h:\w\$ " into ~/.bashrc and execute bash, I get a standard prompt. So it should only be a matter of the correct file name. Note that bash has several files it can process at startup time, such as .bash_login, .profile and .bashrc. Their order is described in the manual, e. g. When bash is invoked as an interactive login shell, or as a non-inter- active shell with the --login option, it first reads and executes com- mands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc. You can find more information in the "INVOCATION" section of the manual at "man bash". There are files for per-user configuration as well as system-wide files. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
