mask files and run command on them?

mask files and run command on them?

[David Belohrad]

Dear all,

could someone give me a piece of advice? I have lots of directories. I'd
like to mark them and then operate a command on each marked directory
separately. 

Typical usage:

dired
mark dirs using 'm'
-do- svn rm command on each of the selected directories



how I could handle this?

thanks
d.

See the code in dired.el and dired-aux.el defining commands that do this.

See function `dired-get-marked-files' and perhaps macros `dired-map-over-marks'
and `dired-map-over-marks-check'.  See how they are used to define such
commands.  See command `dired-do-delete' as an example.

You can also see lots of examples defining such commands in dired+.el:

Have a look at `dired-do-shell-command' in dired-aux.el:

    dired-do-shell-command is an interactive compiled Lisp function in
    `dired-aux.el'.
    
    (dired-do-shell-command COMMAND &optional ARG FILE-LIST)
    
    Run a shell command COMMAND on the marked files.
    If no files are marked or a specific numeric prefix arg is given,
    the next ARG files are used.  Just M-x universal-argument means the current file.
    The prompt mentions the file(s) or the marker, as appropriate.
    
    If there is a `*' in COMMAND, surrounded by whitespace, this runs
    COMMAND just once with the entire file list substituted there.
    
    If there is no `*', but there is a `?' in COMMAND, surrounded by
    whitespace, this runs COMMAND on each file individually with the
    file name substituted for `?'.
    
    Otherwise, this runs COMMAND on each file individually with the
    file name added at the end of COMMAND (separated by a space).

You may need to add a (require 'dired-aux) to you .emacs file to have
it available. It's usuable mapped to '!'.
