Replacing punctuation marks with the help of sed
Code:
#!/bin/bash


a=(*.pdf)

punct=((~`!@#$%^&*()_-+=|\[]{};':",./<>?))

for (( i =0; i < ${#a[i]}; i++ ))
do
sed -ri 's/$punct//g' ${a[i]}
done

I cannot use the above code, can you help me in removing all punctuation marks from file name except file extension. The idea is that once all punctuation are removed then [pdf] can be appended with [.pdf] to save the extensions.

iswpunct

ISWPUNCT(3)						     Linux Programmer's Manual						       ISWPUNCT(3)

NAME

       iswpunct - test for punctuation or symbolic wide character

SYNOPSIS

       #include <wctype.h>

       int iswpunct(wint_t wc);

DESCRIPTION

       The  iswpunct() function is the wide-character equivalent of the ispunct(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "punct".

       The wide-character class "punct" is a subclass of the wide-character class "graph", and therefore also a  subclass  of  the  wide-character
       class "print".

       The wide-character class "punct" is disjoint from the wide-character class "alnum" and therefore also disjoint from its subclasses "alpha",
       "upper", "lower", "digit", "xdigit".

       Being a subclass of the wide-character class "print", the wide-character class "punct" is disjoint from the wide-character class "cntrl".

       Being a subclass of the wide-character class "graph", the wide-character class "punct" is disjoint from the  wide-character  class  "space"
       and its subclass "blank".

RETURN VALUE

       The  iswpunct()	function  returns  nonzero if wc is a wide-character belonging to the wide-character class "punct".  Otherwise, it returns
       zero.

ATTRIBUTES

       For an explanation of the terms used in this section, see attributes(7).

       +-----------+---------------+----------------+
       |Interface  | Attribute	   | Value	    |
       +-----------+---------------+----------------+
       |iswpunct() | Thread safety | MT-Safe locale |
       +-----------+---------------+----------------+
CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, C99.

NOTES

       The behavior of iswpunct() depends on the LC_CTYPE category of the current locale.

       This function's name is a misnomer when dealing with Unicode characters, because the wide-character class "punct" contains both punctuation
       characters and symbol (math, currency, etc.) characters.
