Bash Version: 4.1 Patch Level: 5 Release Status: release Description: The standard .bashrc contains a line of code that precludes certain scripts from executing. It has to do with the logic for checking if the session is interactive. e.g. [ -z "$PS1" ] && return Usually a few other lines are included afterward to, for example, alias 'ls' and to set PS1 to a new value. Some scripts like rvm (rvm.beginrescueend.com) need to run at the tail end of the login process to tack on more data to PATH or set other environment variables (think of it as a post-login hook). These kinds of scripts fail to execute with the code above. Repeat-By: Login. Fix: Here's an alternate method to perform the interactive session check, which accomplishes the same effect in a much safer manner. # Check for an interactive session if [[ ! -z "$PS1" ]] ; then alias ls='ls --color=auto' PS1='[...@\h \W]\$ ' fi This allows scripts at the end of the .bashrc to be sourced/executed under all normal conditions, as well as sourcing of .bashrc from scripts.
