mini-document management script. IF statement question

rmueller58 — Thu, 04 Dec 2008 21:42:33 GMT

Wanted to check and see whether someone might have some insights on how to write a script that will copy files from one location to a second location.

I have a source and a destination.

If the file exists on source and destination with the same name, check to see if the source is newer. if the source file is newer overwrite the destination..

I think the statement would look like this:

if [ "$source" -nt "$destination" ]
then
cp $source $destination
else
echo Destination $destination is a newer file
fi

I define a bunch of variables that set precedent for values in the $source and $destination..
These are CIFS mounted file systems. Scripting solution on Un*x that mounts the file systems in questions and copies from Location A to Location B.

I think I may have my nesting wrong in my scripting
any ideas, suggestions or methods would be appreciated greatly..

Hi:

> I think I may have my nesting wrong in my scripting

Syntatically this is ok. What makes you think this is wrong?

Regards!

I would try something like

cd source_dir
for $source in `ls`
do
if $source does not exist in dest_dir
then copy it
else
if [ "$source" -nt "$destination" ]
cp $source $destination
else
echo Destination is newer
fi
fi
done

this could probably be done with "elif" too?

Sorry, my reply lost the indentation.

James,

I've not use the -nt argument before, we have a web server that allows for job applicants to attach documents, the script takes files from a web server folder and moves them to a CIFS mounted file system for viewing from a 4GL application. often times the copy will bomb out.. or miss a file..

There is a process where we also copy files back to the webserver, the HR clerk will load files into a staging area, and I will list the files and copy them. Last night she loaded 27 files and 6 were missed. For the I create directories if non exist, before the move. What was supposed to have been a temporary work around is now a production must have and it isn't meeting my reliability wishes.

Below is one of the problem scripts. I am wandering it the reliability issues is related to a CIFS issue. Right now all files are moved. I'd like to do only those of "today's date"
That is would reduce network over head and perhaps eliminate timeing issues.

Found resolution and re-wrote script, to eliminate dups and redundancy.
