Please review my script and helpme to get a EXCELENTE script.

Note I need a dynamic script in order to check a IP add connection and if exist a problem send a short messages to mobile list, and continue reviewing next IP add in IPADD.txt.... this is a loop....

I have another issue when ARRIBA flag change from DOWN to UP, dont send short messages. Why, may be I have problems with flags or logical states, where
It looks like you have a lot of issues.

And when i need wite log file $path/NetLogChk its only print date and i need add $MSG, why dont work?
> arriba=1 export arriba
this is wrong syntax, even in ksh
either use
arriba=1
export arriba
or omit the export ('cause you don't need it, did you?)
> .. why dont work?
see:
arriba=0
if [ $arriba -eq 0 ]
then
what should this do, you can omit the if clause

If arriba=0 must check connection until it connect again and netstat|grep be noequal to 0, then perform print and send short messages and change arriba to 1, but dont work.
Other question, when I want write NetLog File, only print date and dont MSG variable, why?

your code looks ok, but which of the echo commands does not work?
Start the script with the -x option to see what's going on ..

You need to fix a few syntax problems and test it again:
1). as ahoffmann already pointed out:
arriba=1 export arriba
i=0 export i
are wrong !
for ksh, you can use:
export arriba=1
or (this will work for sh/ksh/bash)
arriba=1
export arriba
2) path=$HOME/Alex, will cause some kind of confusion with
ENV var $path, consider change to:
fpath=$HOME/Alex
3) while IFS=',' read ip buf ; do
change it to:
IFS=','
while read ip buf ; do
fix up the systax, and then run it in debug more. (put "set -x" in beginning
of your script)
eg:
#!/bin/ksh
set -x
# the body of the script
....

you're using 2 variables: MSG and MSGS
which one is missing?
And again, first fix your syntax problems !

OK I fix parameteres and MSGS varable is not working, when script check IP is UP or connected, this part of myscript dont change variable ARRIBA and dont sens sms.
I has changed path varable but dont writte in LOG FILE. Only date.

use -x option in hashbang line, or set -x
then check what realy happens, probably post relevant output ..

Please post the newer version of the script, and add
set -x
after the first line of the script, make it looks like:
#!/bin/ksh
set -x

....
then run it, and post the out put on your screen.

I just wonder did you read our comments at all?
We alread told you:
"i=0 export i" is WRONG !!!
in your case, you don't need to "export". please read all the comments
carefully, fix the syntax and try again.
