Is there a way to get my emacs to recognize my bash aliases and custom functions when I run a shell command?
bash, emacs, environment-variables, shell
Solution
Below are my comments about what I think was a related question:
I think both M-x shell-command and M-x compile execute commands in an inferior shell via call-process. Try the following in your .emacs (or just evaluate):
(setq shell-file-name "bash")
(setq shell-command-switch "-ic")
I notice that after evaluation of the above, .bashrc aliases are picked up for use by both M-x shell-command and M-x compile, i.e
M-x compile RET your_alias RET
should then work.
My environment: Emacs 24.1 (pretest rc1), OSX 10.7.3

Problem
In my shell environment I have aliases and custom functions. When I am in an instance of emacs (I always use `emacs -nw`) and I execute a shell command (`M-!`) I cannot use them. This makes sense since I imagine it launches it's own subshell to do these... but is there a way (maybe in my `.emacs`) to get this to work? Perhaps even if it involved sourcing an environment by default before executing any shell command given?
