2:38 PM EDT 		How to handle files with names in their blanks correctly with GNU tar?

Lots of music files and directories are that way. For example, on my server my mp3 directory has a sub-directory David Garrett/.

The command "cp -r mp3 /foo/" works correctly -- I get, among other things /foo/mp3/David Garrett/

But when I tar the mp3 directory and then un-tar it under /foo, I get names with quotes in them, e.g., /foo/mp3/'David Garret'/. "scp" does the same thing -- the command "scp -r mp3 someone@somehost/foo/" creates somehost/foo/'David Garret'/ -- again with quotes.

How do I fix this (mis-)behavior?

Personally whenever I get a file with spaces I immediately replace spaces with underscores. I find that to be a time saving step in the long run.

It seems that bash adds the quotes in stdout only, they are not stored in the file names. A GUI file manager does not show any quotes in the file names. tar -tf foo.tar neither.

>lifetimes of wasted effort...replace spaces with underscores

Yep, right or wrong, I agree, and do same.

    for file in *; do mv "$file" `echo $file | tr ' ' '_'` ; done
...but I happily snarfed it to disk and called it ".space2bar" (dotted name so it doesn't show up in an Apache index of the subdir where I use it).

$ for file in * ; do mv "$file" ${file/ /_} ; done
Should also work in ksh. IIRC, ksh had it first.

This would replace the first space only.

for file in * ; do mv "$file" ${file// /_} ; done

replaces all spaces;
