Love ya!

Another question:

how would i be a really cool way (the way u do it) to retrive the one b4 the last ":".
Shall i use "cut" and "tr" or is therean easier way?

also how could i save it to an array once is all checked up? ( you will prob know how to do it in 1 step and i would do it in 300)

Thank you so much!!... you def saved me 4 hrs trying to figure it out and it would never look as neat!SmilieSmilieSmilieSmilie

# modifies global variables ID, NAME, SURNAME, D1, D2, D3
function findid
        # Read entire file line-by-line hunting for $1
        while IFS=":" read ID NAME SURNAME D1 D2 D3
                # Return success if we find it
                [ "$ID" = "$1" ] && return 0
        done <users.db
        # didn't find it.  return error.
        return 1

if findid 999
        echo "Found ID $ID name $NAME surname $SURNAME d1 $D1 d2 $D2 d3 $D3"
        echo "Couldn't find $ID"

thank you!
you are a star! =)
i reckon that to write into the db
i change the read for write?

Old 09-01-2011
nope. To write to it, you do something like
echo "a:b:c:d:e:f" >> users.db

Note the double->. A single > will OVERWRITE the file instead of appending it so be careful.
