I'm trying to start emacs from the command line and using an --eval section to
open a file and do some operations. I'm having a problem with the Linux version.
Here's how I do it without error using the strange quoting in Windows:
---> emacs --eval ^"( find-file c:/users/myname/somefile.org\^" )^"
In Linux I'm not sure how to do the quoting. I tried this:
---> emacs --eval "( find-file "/home/somefile.org" )"
And I get the error:
Symbols' value as variable is void: /home/somefile\.org
It seems there's some problem with the period in the filename, but maybe it's
more than that. Can anyone explain how to properly quote the Linux commandline
version? (File comes up fine if I just do find-file in a running emacs.)
Thanks,
Herb

Provided you don't use any completely exotic shell, that is what Emacs
gets to see:
( find-file /home/somefile.org )

A safe way to quote this particular invocation:
emacs --eval '( find-file "/home/somefile.org" )'
This only works in tcsh
emacs --eval "( find-file \\"/home/somefile.org\\" ) "
Bash needs this instead
emacs --eval "( find-file "'"'"/home/somefile.org"'"'" ) "
THere may be other solutions for bash, but I never really got the hang
of their quoting rules.

Achim.

Thanks a lot, that Bash version works great. I'll have to check into quoting
rules for the Linux shells.
Regards,
Herb

Hi,
This works on Bash (tested on 4.2.10) and should be easy to remember:
emacs --eval "(find-file \"/home/somefile.org\" )"
Cheers,
Viktor

I thought I had tried already that but I hadn't. Thanks Viktor.

The even simpler solution worked for me:
emacs --eval '(find-file "/home/somefile.org")'
with bash (4.1-3) on Debian Linux (testing+unstable). Not sure why
others have needed so many escapes on quotes... note that I'm enclosing
the sexp in single quotes. Has something changed in bash from 4.1 to
4.2?

...as I had already said (this also has the charm of working in other
shells, like tcsh).

For this simple example it's a wash, but sometimes you can't use single
quotes (for instance if you want to have variable expansion) and then
you will still need to know how to escape stuff.

Achim.

Ah, sorry, I missed that!
