You can create different RETVALs if you
to the
number of items it imported.
I would like BASH to trap this value and at the end echo the total of the 4
script executions.

Not sure what you're really trying to do. If you posted real code, that
would help.

a sadly-overlooked but useful text processing command is "expr".
$ man expr
which can do simple things like matching, extraction, length,
substr and stuff like that. check it out before going on to sed,
You want to use sed and awk for a truly robust solution.
If you need further help, I can dig up examples of doing this.
Generally, when I need to do text processing, I turn to perl. However,
this can be done in bash, but larger tasks will get ugly in bash.

you can use xargs to get rid of that whitespace in the protocol declaration:
BLOCKED_SERVICES="tcp,111,Sun RPC;\
udp,111,Sun RPC;\
tcp,443,Microsoft DS;\
udp,443,Microsoft DS"
IFS=";"
for SERVICE in $BLOCKED

Not the way you're doing it. The easiest thing to do is to change your
data representation, rather than spending a lot of time trying to strip
whitespace. Try:

You're right, that's an odd inconsistency. I thought perhaps we could
modify IFS, but it uses space/tab/newline by default, yet it doesn't
seem to be splitting on the space in the first example. (I would
think it should.) These two commands produce i
Use quotes.. these things ---> " "

I didn't get to read your whole message, but quotes protect text from
default parameterization rules of the shell, etc.
Therefore: cat "Filename with spaces.txt"
will.. well.. you get the idea
A common script I do do is like:
for f in *.c
do
echo -e "$f"
Put double-quotes around your variables. :)
