Edit: I see this thread was a duplicate, and you got a much more complete answer from Watael in the other thread :)

Hello freebash! If you're still looking for a solution, sed is probably a good place to start. You could use sed to search and replace the commas with newlines.

OR you could look into awk. You could set the comma as the field separator, read in each line of input, and put newlines in the output.

I know it's an old thread, but I hate seeing questions without answers. I hope this helps somebody!

# sed
# Substitute / ,  /  (with a)  newline / Globally (each occurrence) and then Print
sed -rn 's/,/\n/gp'  yourFile

# cat file to pipe and TRanslate each , into \n
cat yourFile | tr ',' '\n'

# we set the RecordSeparator to , an just print the lines.
# the default OutputRecordSeparator is still a newline.
# a kind of implicit conversion.
awk -v "RS=," '{print}' yourFile

# doing it with bash alone
while read line; do   # we read line for line into a var called "line"
    IFS="," array=( $line )  # set the InternalFieldSeparator of bash to a "," and split the line into an array
    for a in ${array[@]} ; do  # we loop over the array
         echo ${a}  # and print each entry
     done   # values now in array are deleted implicitly by next assingment in line IFS.....
done < <(cat yourFile)   # we read the file with process substitution.
