some issues with file renaming with arrays
Hi! guys! again with some problem solving issue. The problem is that I have few files in a folder some are with extension .txt and some are not so how to put them all with .txt extension minus the shell script which i usually put in the same folder. I tried making it out, but there is some problem. Here is the code and details below.

Code:
#!/bin/bash
# program for file renaming
echo "Enter path: "
read p # pattern should be *.txt, *.pdf or simply *
a=($p)

for (( i = 0; i < ${#a[*]}; i++ ))
do
echo "a[$i] = ${a[$i]}"
done

echo "Enter the file format: "
read f   # can be given as txt or pdf

for (( i = 0; i < ${#a[*]}; i++ ))
do
for (( ${a[$i]} != "frn2c" ))
do
v[$i]=("$(cat ${a[$i]} | sed 's/\(.\)/\1 \n/g')")
echo ${v[$i]}
c[$i]=("$(mv ${v[$i]} ${v[$i]}.$f)")
echo ${c[$i]}
done
done

And, the problem is denoted with this line
Code:
for (( ${a[$i]} != "frn2c" ))

The error is
Code:
./frn2c: line 17: syntax error: arithmetic expression required
./frn2c: line 17: syntax error: `(( ${a[$i]} != "frn2c" ))

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
