Hi,

The inode thing is exactly what I've always done in this situtation. But I just thought I'd have a play about and see if I could find another answer, and there's this approach too (which might be handier if you need to script this on a regular basis, for some really weird reason).

On up-to-date Bash on modern Linux, you can use a regex like this:

[^[:print:]]

to match non-printable characters only. I created a file with the same name as yours, and some other besides, and here's a sample session showing that regex in action.

Code:

$ ls -lb
total 0
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Right
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 15:58 Wrong\033[D\033[D\033[D\033[D\033[DRight
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong\ Filename.csv
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Wrongness
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong.txt
$ ls Wrong[^[:print:]]*
Wrong?[D?[D?[D?[D?[DRight
$ rm -v Wrong[^[:print:]]*
removed 'Wrong'$'\033''[D'$'\033''[D'$'\033''[D'$'\033''[D'$'\033''[DRight'
$ ls -l
total 0
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Right
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong Filename.csv
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Wrongness
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong.txt
$

So if you absolutely needed to automate the removal of such things, this might be a useful approach if your shell and/or distro support it.

hxunent

HXUNENT(1)							  HTML-XML-utils							HXUNENT(1)

NAME

       hxunent - replace HTML predefined character entities by UTF-8

SYNOPSIS

       hxunent [ -b ] [ -f ] [ file ]

DESCRIPTION

       The  hxunent  command  reads  the  file	(or standard input) and copies it to standard output with &-entities by their equivalent character
       (encoded as UTF-8). E.g., &quot; is replaced by " and &lt; is replaced by <.

OPTIONS

       The following options are supported:

       -b	 The five builtin entities of XML (&lt; &gt; &quot; &apos; &amp;) are not replaced but copied unchanged. This is necessary if  the
		 output has to be valid XML or SGML.

       -f	 This  option  changes	how  unknown  entities or lone ampersands are handled. Normally they are copied unchanged, but this option
		 tries to "fix" them by replacing ampersands by &amp;. Often such stray ampersands are the result of copy and paste of URLs into a
		 document and then this option indeed fixes them and makes the document valid.

DIAGNOSTICS

       The program's exit value is 0 if all went well, otherwise:

       1	 The input couldn't be read (file not found, file not readable...)

       2	 Wrong command line arguments.

SEE ALSO

       asc2xml(1), xml2asc(1), UTF-8 (RFC 2279)

BUGS

       The  program assumes entities are as defined by HTML. It doesn't read a document's DTD to find the actual definitions in use in a document.
       With -f, it will even remove all entities that are not HTML entities.
