special character problem

[kerasi]

Hello

i have a .mp4 file which i will convert to .mp3 but i can't escape the characters at the beginning

~ _ Notis Sfakianakis ~ Dose ena telos-uAGmYjSm_i8.mp4

i hope someone can help me

If the filename is as you've posted, all you should need to do is surround the filename in double-quote characters. For example:

$ mv "~ _ Notis Sfakianakis ~ Dose ena telos-uAGmYjSm_i8.mp4" my.video.mp4

If the file has non-printable characters in the name, you may be able to address it with wildcards:

$ mv *i8.mp4 my.video.mp4

If both methods fail, you can manually rename the file to ASCII characters with fsdb(8).

... be sure to read its manual. Here is an example of using its chname subcommand to rename a file.

I have created this simple filesystem, containing the directory structure path/to/directory and the innermost directory, directory holds two files: "a.file" and the file I wish to change, "bad.file".

$ ls -R
path

./path:
to

./path/to:
directory

./path/to/directory:
a.file   bad.file

This happens to be a filesystem I created for the example: vnd0a. Here's what the change steps look like, starting with the character (raw) device node, and an unmounted filesystem.

# fsdb -f /dev/rvnd0a
** /dev/rvnd0a
** File system is already clean
