(do you *have* a .bash_login or .profile?) a very common bash idiom is to have "[[ -f ~/.bashrc ]] && . ~/.bashrc" in .bash_profile. is this OS X or linux/bsd/cygwin windows/something else? i've heard reports of shell initialization differences in OS X zsh, so there might be issues in bash too. -- Aaron Davies aaron.dav...@gmail.com _______________________________________________ screen-users mailing list screen-users@gnu.org https://lists.gnu.org/mailman/listinfo/screen-users
