I have a file system called /datafiles. Within this file system I allow remote users to upload files to me with the structure of "upload.0002", "upload.0003", "upload.0004", etc. I want to monitor this directory with a Korn script running at certain times via crontab, that will identify when one of these files exist then run a series of commands on the file that is found. I need to:

1) Be able to identify the file when it is present and has been completely uploaded

2) Discover the files extension (i.e. 0002, 0003, 0004, etc.)

3) Run a series of commands of the file using its extension as an argument.

hi,

find your_dir -name 'upload*' |wc -l gives you number of upload file in your directory

ls -l your_dir | awk '{ FS="." ;print $2 }' gives you file extension.

hope this help you

The following (untested) code tests if a file has updated in the last 60 seconds. If it hasn't, assume it is completely uploaded and process it.

HTH

processFile ()
{
local fileName=$1
local fileExtension=$2
# doStuffWithFile
}

# Main Processing

for fileName in uploadDirectory/upload.[0-9][0-9][0-9][0-9]
do
fileExtension=${fileName#*.}
fileTest=/tmp/$fileName.$(date +%d%m%y_%H%M%S)
cp -f $fileName $fileTest
sleep 60
test "$fileName" != "$(find $fileName -newer $fileTest)" > /dev/null && processFile fileName fileExtension
done
