I know I can see the file with eg. cat, but: what could I do to
"process" each line of the file ?

Thanks

And why do you propose

cat filename | loop

when you can do

loop < filename
i agree, this ia another improvement possible in the script

?

Last but not least,

echo "$currentline"

should be "quoted", so shell does variable substitution but
no other expansions.
i would like to know what other expansions could the shell do when
there is no quote(") ?
