Replied new files
We need to create a process that run continues and whenever a file is placed in a specific directory, the process detected this new file and replicated in another directory.
How can we implement a process that allows automatic replies to the new files?


Regards

take a look at the rsync utility.

Option 1: Use rsync from one directory to the other
Option 2: Use File::Monitor
Option 3: If you're on Linux, code something up in C using inotify
Option 4: (might miss files)
Code:
cd /incoming
while true
do
    filename=$( basename $( ls -1t ) )
    if [ ! -e /replicate/${filename} ]
    then
        cp /incoming/${filename} /replicate/.
    fi
    sleep 30
done

Obviously 'ls -1t' in 'filename=$( basename $( ls -1t ) )' returns more than one file name, a thing which basename can't handle with. Try:
Code:
cd /incoming
while filename in "$(ls -1t)"
do
     if [ ! -e "/replicate/${filename}" ]
...

P.S. I didn't use basename at all, since /incoming may have subdirectories with files, which also should be taken into account while generating replicates

Wich values you will pass to filename ?

while filename in "$(ls -1t)"

I've made an error no double quotes are needed around $(ls -t)

To show, what values the variable filename gets, here is my example:
>cd sample_dir/

>ls -t
file3
file2
file1

> for filename in $(ls -t) ; do echo "filename is $filename" ; done
filename is file3
filename is file2
filename is file1
