Hey , can you pls explain what the script is doing , I am working on a similar kind of script.
does the script needs filename as input or will it convert all the .txt files in path to files dir to .csv files.I tried to execute the script it is giving an error as invalid iname

can you explain me the below part
while read FILENAME
do
tr '|' ',' < "$FILENAME" > "${FILENAME}.csv"

Thanks for your time
