i have install Emacs and im trying to able the possibility to go to the definition of a function or a variable:

You can find this text below here:

Assuming CODEDIR to be the top-level source directory, first update your ~/.bashrc like so:

alias mktags='cd $CODEDIR && etags `find $CODEDIR -name "*.[h|c]"` && cd -'

Then run:

source ~/.bashrc

Now, inside ~./.bashrc i have this line:

alias mktags='cd /opt/lampp/htdocs/rs && etags `find /opt/lampp/htdocs/rs -name "*.[h|c]"` && cd -'
My problem: when i execute "mktags", it says:

etags: no input files specified.
Try `etags --help' for a complete list of options.

What's wrong?
