Michael,
I've been using something like the following, though I'm sure it could be
written more concisely:
if status --is-login
# We are the login shell
# Inteligently update $PATH
# Add some stuff to the path
set -l path_list /usr/local/bin /usr/local/sbin /usr/local/share/python
/usr/local/share/python3 /usr/local/bin/include /usr/local/bin/lib
/usr/local/share/npm/bin
# For each item in PATH, if it isn't in path_list and it is a valid directory
then add it to path_list
for item in $PATH
if not contains $item $path_list
if test -d $item
set path_list $path_list $item
end
end
end
# For each item in path_list, if it is a valid directory then add it to temp
for item in $path_list
if test -d $item
set temp $temp $item
end
end
# Set path to temp
set -x PATH $temp
end
