+@cindex invocation (command line arguments)
GNU Emacs supports command line arguments to request various actions
when invoking Emacs. These are for compatibility with other editors and
ordinary editing.
Arguments starting with @samp{-} are @dfn{options}, and so is
-@samp{+@var{linenum}. All other arguments specify files to visit.
+@samp{+@var{linenum}}. All other arguments specify files to visit.
Emacs visits the specified files while it starts up. The last file
name on your command line becomes the current buffer; the other files
are also visited in other buffers. If there are two files, they are
Emacs library search path as specified with @env{EMACSLOADPATH}
(@pxref{General Variables}).
+@strong{Warning:} If previous command-line arguments have visited
+files, the current directory is the directory of the last file
+visited.
