BASH script to Email list of “new” files found

Posted on Updated on

This is a quick-and-dirty script that I made to solve a real world scenario.  I had to find a way to notify a data integration group of any new files that an outside vendor had sent up to our secure FTP SUSE Linux server.  These were batched up into many, many files, all starting with the same few characters.  This made it fairly easy to add a wildcard search, but the other parts deal with the fact that only NEW files needed to be identified, not any existing files that were already processed internally by the data integration group.

#!/bin/bash

OLD=/root/filecheck/old.log
NEW=/root/filecheck/new.log
DIFF=/root/filecheck/diff.log
RCPT=user@user.com

# write an "old" file listing if first time run

if [ -f $OLD ]; then
 ls -la /path/to/filetype/filetype* | awk '{print $9}' > $OLD
fi

# take a snapshot of the directory now, possibly capturing new files

ls -la /path/to/filetype/filetype* | awk '{print $9}' > $NEW
diff "$OLD" "$NEW" >> "$DIFF"

# new file listing now becomes "old" for next run

cat $NEW > $OLD

# if new files are found, log and send out a message

if [ -s $DIFF ]; then
cat <<EOF | /usr/sbin/sendmail -t
To: $RCPT
From: sftp@sftp-server.company.net
Subject: New Files Found
`cat $DIFF`
.
EOF
fi
