If either of these is not true, the most portable 9# (and convenient) thing to do is to make an alias called emacs which 10# refers to the real program, e.g. 11# 12# alias emacs=/usr/local/bin/gemacs 13# 14# Written by Noah Friedman. 15 16function edit () 17{ 18 local windowsys="${WINDOW_PARENT+sun}" 19 20 windowsys="${windowsys:-${DISPLAY+x}}" 21 22 if [ -n "${windowsys:+set}" ]; then 23 # Do not just test if these files are sockets.
