Script to monitor any modifications in files in my FTP site

Question

Iam trying to build a script to monitor any modifications in files in my FTP site. The script is given below. I have used wc -l to count the no. of files in the directory and have defined the constant value of files if there is going to be any modification in files like if my co-worker updates in my FTP this will send me a notification. Am trying to cron this to achieve. But the script actually just hangs after the count . It doesn't provide me the expected result. Is there anything that am wrong with the code. Am just a beginner in Bash could anyone help me solve this

#!/usr/bin/bash
curl ftp://Sterst:abh89TbuOc@############################/Test/| wc -l ;
read b;
a=9
if [ "$b" != "$a" ];
then 
echo  "FTP dir has modified mail" -s "dir notification" sni912@######.com;
fi

iwatch command am not able to do it for an FTP. Is there any way? — Sathish, Feb 23 '14 at 17:29
Do you have shell access to the FTP server, or do you only have FTP access? — glenn jackman, Feb 23 '14 at 17:53

A couple of notes about your code:

#!/usr/bin/bash
curl ftp://Sterst:abh89TbuOc@############################/Test/| wc -l ;
read b;

That does not do what you think it does: the wc output goes to stdout, not into the read command. Do this instead: b=$( curl ... | wc -l )

a=9
if [ "$b" != "$a" ];

Since the wc output will have some extra whitespace, better to do a numeric comparison:
if (( a != b ))

then 
echo  "FTP dir has modified mail" -s "dir notification" sni912@######.com;

You probably mean this:

echo  "FTP dir has modified" | mail -s "dir notification" sni912@######.com;

I would write this:

listing=$( curl ftp://... )
num=$( echo "$listing" | wc -l )
if (( num != 9 )); then
    mail -s "ftp dir modification" email@example.com <<END
FTP directory modification

$listing
END
fi

I was unaware that curl would return a listing for `ftp://host/directory/`, that's pretty cool. – glenn jackman Feb 23 '14 at 18:04
hi glenn, i didn't try the suggestions provided by you yet but on the first look it is superrvv thanks a lott will post once trying the same – Sathish Feb 24 '14 at 08:08
am getting the below error Syntax error: "fi" unexpected (expecting "then") – Sathish Feb 24 '14 at 13:55
did you forget a semicolon, or the "then"? – glenn jackman Feb 24 '14 at 14:53
still am finding it difficult am getting the below error. testnew.sh: line 6: syntax error near unexpected token `fi' testnew.sh: line 6: `fi' – Sathish Feb 24 '14 at 16:26
that was cause of some formatting prob i guess it worked after dos2unix but still have a different prob testnew.sh: 4: testnew.sh: num: not found – Sathish Feb 24 '14 at 16:50
The mail command is waiting for you to type the body of the email and press Ctrl-D – glenn jackman Feb 24 '14 at 17:09

My code

listing=$( curl  ftp://username:password@ftp.com/test/ )
num=$( wc -l | echo "$listing" )
if (( num != 9 ));
then
mail -s "ftp dir modification" email@example.com
fi `
