I was under the (perhaps mistaken) impression that "source" does work in
bash.
I have had "source /sw/bin/init.sh" in my ~/.bashrc since I started
playing with Fink and the $PATH has always appropriately included the
directories that /sw/bin/init.sh adds to it.
And I checked the man page for bash:
source filename [arguments]
Read and execute commands from filename in the cur-
rent shell environment and return the exit status
of the last command executed from filename. If
filename does not contain a slash, file names in
PATH are used to find the directory containing
filename. The file searched for in PATH need not
be executable. When bash is not in posix mode, the
current directory is searched if no file is found
in PATH. If the sourcepath option to the shopt
builtin command is turned off, the PATH is not
searched. If any arguments are supplied, they
become the positional parameters when filename is
executed. Otherwise the positional parameters are
unchanged. The return status is the status of the
last command exited within the script (0 if no com-
mands are executed), and false if filename is not
found or cannot be read.
I could be wrong, but I thought that the only difference between "."
(dot) and "source", as far as the bash shell is concerned, has to do
with the inheritance of environment variables from one subshell to the
next. Like I said I could be wrong, though, that's just what I think I
read somewhere. I use "source" because it's a tiny bit more legible.
Should I switch all of my shell scripts to use "." instead?
