How do I remove ._ from beginning of filename?

I have several files' names starting with "._". I'd like to remove the point and underscore in a script. Howto do this?

Thank you very much in advance.

  1. This is a dry-run (simulates the command, doesn't execute it):

    rename -n 's/^\._//' ._*

    If you like the output, execute it:

    rename -v 's/^\._//' ._*

  2. using rename:

    rename -v 's/\._//' ._*

    example:

    $ touch ._aaa
$ rename -v 's/\._//' ._*
._aaa renamed as aaa

  3. Your question can be interpreted in two ways, "renaming" and "get the filename with ._ removed". For rename, see the other questions. For the second possibility, use variable expansion:

    name=._file
stripped_name="${name#._}"
# the below will output: ._file becomes file
echo "$name becomes $stripped_name"
