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
