Top Forums Shell Programming and Scripting Script to FTP a modified file Post 302592193 by PyroPlasm on Monday 23rd of January 2012 11:36:16 AM

I apologize. I think what I was given earlier is a great help. To be more specific we have an HTML file that is being output by a Java class. That HTML file will reside in a folder and the Java to create the file will be run on a recurring basis. We just want to see if something changes in the HTML file and if it does we FTP it over to another server and that's what this script is supposed to do when the Java class calls it.

---------- Post updated at 11:36 AM ---------- Previous update was at 08:38 AM ----------

I found an issue with the script. It copies the file no matter what. I tested this by grabbing a new HTML file that has not been changed at all and ran the script and it copied it. Below is my new code:

Code:
#!/bin/sh
#
#
# MD5FILE-parameter specifies where we want to save our md5print for
# later use.
MD5FILE=/tmp/.md5savefile

# The FILE_TO_CHECK-parameter specifies the file we want to monitor
# changes
current_date=`date +%Y%m%d`
FILE_TO_CHECK=MSN.htm

if [ ! -f $FILE_TO_CHECK ]
then
echo "ERROR Couldnt locate file to check:$FILE_TO_CHECK"
exit 1
fi

echo "Taking a print on $FILE_TO_CHECK with md5sum"
MD5PRINT=`md5sum $FILE_TO_CHECK | cut -d " " -f2`

if [ -z $MD5PRINT ]
then
echo "ERROR Recived an empty MD5PRINT thats not valid, aborting"
exit 1
else
echo "MD5PRINT we got was:$MD5PRINT"
fi

if [ -f $MD5FILE ]
then
echo "Found an old savefile:$MD5FILE we trying to match prints"
OLDMD5PRINT=`cat $MD5FILE`

if [ -z $OLDMD5PRINT ]
then
echo "Got an empty string from the oldfile, aborting"
exit 1
fi

if [ "$OLDMD5PRINT" = "$MD5PRINT" ]
then
exit 1
else
cp MSN.htm  MSN.$current_date.htm
fi

fi

echo "Saving to new md5print in logfile:$MD5FILE for later checks"
echo $MD5PRINT > $MD5FILE

if [ $? = 0 ]
then
echo "Wrote to file OK"
else
echo "Writing to file failed...why??"
exit 1
fi

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
