File timestamping issue
Hello,

I am working on moving a data file to archive dir from the processing directory using the following lines in my FTP script. Sometimes the mv command does not work as the timestamp is is changed by seconds as the current date in the following code is changed.

I have tried to use ts='date +%C%y%m%d%I%M%S` variable to append to the file name but that does not work.

Here is the code that is relevant:
Code:
 
files=$(ls $intfiles.pgp 2> /dev/null | wc -l)
if [ $files -ne 0 ]
then
echo "Creating a copy of the file receivied in the Archive dir"
for a in $mvfiles
do
cp "$a" "$a.`date +%C%y%m%d%I%M%S`"
mv "$a.`date +%C%y%m%d%I%M%S`" $ARCHIVE_DIR
done
else
echo "The data files were not generated."
exit
fi

can you explain the below line

Sometimes the mv command does not work as the timestamp is is changed by seconds as the current date in the following code is changed.

Also, what is in the $mvfiles ?

mvfiles are the file I am trying to move to archive dir.

mvfiles=path to my current files that have been generated by a program
$ARCHIVE_DIR=path to the archive dir where the file(s) are supposed to be moved so there is a timestamped copy.


If the timestamped file created is SomeDataFile.TXT.20120820103149 by the cp command the mv command might be looking for SomeDataFile.TXT.20120820103209 as the system date from the 'date +%C%y%m%d%I%M%S` might have changed between the cp and mv command.

If your problem is that the two date commands return slightly different results, then the most obvious solution is to only run it once and store the value.

try the below code b/w the do and done

Code:
currenttime=$(date +%C%y%m%d%I%M%S)
newfilename="${a}.${currenttime}"
cp "${a}" "${newfilename}"
mv "${newfilename}" $ARCHIVE_DIR

instead of copying to the same directory and move it to archive directory, you can use the cp command directly.

Code:
newfilename="${a}.$(date +%C%y%m%d%I%M%S)"
cp "${a}" "${ARCHIVE_DIR}/${newfilename}"

itkamaraj,

wow! That worked perfectly.

I have tried the direct copy before with the cp to archive/newfilename in the second set of example code, but it does not seem to work on linux.

Thanks again!
