diff



hi all,


i want to do this shell script.

create a script that will check the transferred file vs. orig file.
1. diff the file1 and file2
2. if difference found, retain the original file and email to netcracker team.
3. if no difference found, delete the previous file and retain the new 1.

code:
/usr/bin/diff $f_path/$f_name1 $f_path/$f_name2 >> /dev/null 2>&1

if [ $? -eq 0 ]
then    # no change
        rm $f_path/$f_name1
else        # change
        rm $f_path/$f_name2
        uuencode $f_path/$f_name1 $f_name1| mailx -s "$f_name1 changed" $nc_email
fi

that should do basically what you need it to, unless i misunderstood the requirements.

you'll need to add the file transfer bits above that block yourself.

thanks,

it's working now. i just want to add some checking.

1. if $f_name does not exists,
call the script and it still problem, call again (10x).

this should take care of it:


code:

for x in 1 2 3 4 5 6 7 8 9 10
do
        ### file transfer code    ###
        ### should be placed here ###

        if [ -f $f_name1 ]        # tests to see if file 1 exists
                                # -s would check for existance and size > 0
        then
                /usr/bin/diff $f_path/$f_name1 $f_path/$f_name2 >> /dev/null 2>&1

                if [ $? -eq 0 ]
                then    # no change
                        rm $f_path/$f_name1
                        break
                else        # change
                        rm $f_path/$f_name2
                        uuencode $f_path/$f_name1 $f_name1| mailx -s "$f_name1 changed" $nc_email
                        break
                fi
        else
                sleep $sleep_int  # interval to sleep in seconds
        fi
done
