There's one problem with your proposed shell wrapper: it doesn't work
correctly in the presence of symbolic links, since when invoking the
symbolic link "$0" will be the name of the symbolic link, not the name
of the *target* of the symbolic link.
MCS has a solution, but it depends on autoconf (mono's scripts/mcs.in
file is processed, including the full path to mcs). As such, it may be
So, here's my attempted solution. It checks for the presence of
symlinks, and looks up the target of the symlink (using readlink) if
necessary, before passing off the program to mono:
# Starts a CIL program whose name is patterned after the filename of
# this script. The CIL program executed is "$0".exe.
# If file is a symlink, find where it's pointing to
if [ -L $file ] ; then
if ! (readlink -f "$file") > /dev/null 2>&1; then
echo `basename "$0"` ": missing required program readlink!"
file=`readlink -f "$file"`
exec mono "$file.exe" "$@"
