Code:
i=0
for file in `ls $filename`
do 
   echo "$file"
   #echo $i
   i=`expr $i + 1`
   newName=`basename $file .txt`
  mv $src_dir/${file} $src_dir/${newName}_${i}.txt
done

dont use ls in the below line

Code:
 
for file in `ls $filename`

if you want to replace all the files under your src_dir then use it like

Code:
 
for file in *

NAME

       rename - renames multiple files

SYNOPSIS

       rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]

DESCRIPTION

       "rename" renames the filenames supplied according to the rule specified as the first argument.  The perlexpr argument is a Perl expression
       which is expected to modify the $_ string in Perl for at least some of the filenames specified.	If a given filename is not modified by the
       expression, it will not be renamed.  If no filenames are given on the command line, filenames will be read via standard input.

       For example, to rename all files matching "*.bak" to strip the extension, you might say

	       rename 's/.bak$//' *.bak

       To translate uppercase names to lower, you'd use

	       rename 'y/A-Z/a-z/' *

OPTIONS

       -v, --verbose
	       Verbose: print names of files successfully renamed.

       -n, --no-act
	       No Action: show what files would have been renamed.

       -f, --force
	       Force: overwrite existing files.

ENVIRONMENT

       No environment variables are used.

AUTHOR

       Larry Wall

SEE ALSO

       mv(1), perl(1)

DIAGNOSTICS

       If you give an invalid Perl expression you'll get a syntax error.

BUGS

       The original "rename" did not check for the existence of target filenames, so had to be used with care.	I hope I've fixed that (Robin
       Barker).
