I want to remove all special characters in front of a list of file
names (which may be generated by the "find" or other commands).
How to do that?
This does not work:
$ find . -type f -print | perl -pe 's/([?|*.\'"])/\\$1/g'
>
$ find . -type f -print | perl -pe "s/([?|*.\'"])/\\$1/g"

So I can only guess that this s/// does additional unwanted substitutions in
the middle of the text. This is because you forgot to anchor the RE to the
beginning of the string.

find . -type f -print | perl -pe 's/([?|*.\047"])/\\$1/g'

The problem is that a '>' appear for
$ find . -type f -print | perl -pe 's/([?|*.\'"])/\\$1/g'

Sorry, I don't understand the meaning of "to anchor the RE to the
beginning of the string."
Do you mean:
$ find . -type f -print | perl -pe 's/^([?|*.\'"])/\\$1/g'
>
$ find . -type f -print | perl -pe "s/^([?|*.\'"])/\\$1/g"

Both does not work:(.
e.g. for this output:
$ find . -type f -print
../VERSION
../RELEASE
My desired output will be:
VERSION
RELEASE
This does not work:
$ find . -type f -print | perl -pe 's/([?|*.\047"])/$1/g'
../VERSION
../RELEASE

try:
find . -type f -print | perl -pe 's/^\W+//'

You mean you want the base name? This will do what you're asking in the
example above (you don't need Perl necessarily):
find . -type f -exec basename {} \;
Are you trying to do something else? Show some more examples (what you
had above was great, by the way).

I have a _very_ strong suspicion that we are looking at an x-y-problem.
You want to achieve something and you believe, removing "special" characters
from the beginning of the string is the best way to do it. Therefore you are
asking how to remove special characters. That would be the Y.
From you sample data I gather you are dealing with file names and I'm
guessing you want to get the basename of the file. That would be the X.
The right tool to do that would be File::Basename.
As for blindly removing those characters that you mentioned earlier
[?|*.\'"] are you aware, that in most file system many if not all of them
can be part of a regular file name? Do you really want to change the file
name if it starts with one of your "special" characters?

It turns out that all I want is the dirname and basename.
Thanks.
