Problem iterating in while loop
I am facing a problem in replacing the file contents by iterating through the list.

My present code:



Code:
Code:
#!/bin/bash#

TFILE="/tmp/vinay/testb_1.txt"
while read linedo  
aline="$line"                
echo $aline   
code=`echo $aline|cut -d ',' -f1`   
country=`echo $aline|cut -d ',' -f 2`
sed "s/$code/$country/g" testb_1.txt>testb_1.txt
sed 's/$/| testb_1.txt/g' "$TFILE" > "output1.txt"
echo $codeecho $countrydone<country_code.txt


and my

country code file contains some county code on line basis, seperated with commas.

Here after executing the script, only last country code is replacing with its country name. And if I change > (overwriting) to >> (appending) then same contents, multiple times with changes are appending to output file. I request you to suggest a solution for this.

And my second concern is that I have to append the name of the file at the end of each line, which I hav done using the commented line. Request you to suggest to perform both actions at a stretch.

Thanks.,

NAME

       MARC::Charset::Code - represents a MARC-8/UTF-8 mapping

DESCRIPTION

       Each mapping from a MARC-8 value to a UTF-8 value is represented by a MARC::Charset::Code object in a MARC::Charset::Table.

METHODS

   new()
       The constructor.

   name()
       A descriptive name for the code point.

   marc()
       A string representing the MARC-8 bytes codes.

   ucs()
       A string representing the UCS code point in hex.

   charset_code()
       The MARC-8 character set code.

   is_combining()
       Returns true/false to tell if the character is a combining character.

   to_string()
       A stringified version of the object suitable for pretty printing.

   char_value()

   to_string()
       Returns a stringified version of the object.

   utf8_hash_code()
       Returns a hash code for uniquely identifying a Code by it's UCS value.

   default_charset_group
       Returns 'G0' or 'G1' indicating where the character is typicalling used in the MARC-8 environment.

   get_marc8_escape
       Returns an escape sequence to move to the Code from another marc-8 character set.
