my working solution
Hi guys,

thanks for all your inputs.
i was able to work with my problem using this:

Code:
#!/bin/bash

FILE_NAME=1.csv

while read fileline
do
	OLDIFS=IFS
	IFS="=" flds=( $fileline )
	nrofflds=${#flds[@]}
	
	ctr=0

	while [[ $ctr -lt $nrofflds ]]
	do
		echo "${flds[$ctr]}"
		ctr=$(($ctr+1))
	done
			
	IFS=OLDIFS
done < $FILE_NAME

this prints the value of the columns per record per file line.
thanks for all your help! SmilieSmilieSmilie
