UNIX for Dummies Questions & Answers

Hi

I am new in unix and look for help in urgent.

I have a list of data files that located in a directory, and need to copy to another directory for loading. The condition here is, the list of data files has to be copy over by sequence, and if there is no file in targetted directory already.

Please give me some light.

Code:

cd ${SRCE_DIR}
for FILE in `ls -altr ${SOME_FILEMASK_IF_REQUIRED}` 
do

  if [ ! -f ${DEST_DIR}/${FILE} ]
  then
    echo 'Transferring file: '${FILE}
    cp ${SRC_DIR}/${FILE} ${DEST_DIR}/${FILE}
    echo 'Transfer completed.'
  else
    echo 'The file: '${FILE}' already exists in '${DEST_DIR}'.'
  fi

done

The above was done off the cuff, so you'll just need to check it.

Hope it helps.

Cheers,
Cameron

Hi Cameron,

Thanks for the prompt reply. The script really help me to get an idea.
Still have some doubt here.

I have modified the script to as below. I put all the datafile name from the source directory into a file name "mydatafile", in tend to load the datafile by the ordering in the file. The data able to pick up one by one when the destination location has no data, but is not follow the sequence order in the file. How to make it read the file by order?

mydatafile

GGESC00A.2004:01:19:05:15:00.CLIpm
GGESC00A.2004:01:19:05:30:00.CLIpm
GGESC00A.2004:01:19:05:45:00.CLIpm


#!/bin/ksh

while [ -f /tmp/hs/source/* ]
do

while read line
do
echo $line

if [ ! -f /tmp/hs/destination/* ] && [ -f /tmp/hs/source/* ]
then

echo 'Transferring file: '$line >> seq_log
mv /tmp/hs/source/$line /tmp/hs/destination/
echo 'Transfer completed.'

else
echo 'File: '$line': loading in progress######'
while [ -f /tmp/hs/destination/* ]
do
echo '**********'
done
sleep 5
if [ ! -f /tmp/hs/destination/* ] && [ ! -f /tmp/hs/source/* ]
then
echo 'File: '$line': loading completed'
fi
fi

done < mydatafile
done

Sadly your script generates nothing my a lot of " ********** ".

Using what I provided before you should be able to :

Code:

#!/bin/ksh

SRCE_DIR=${HOME}/srce
DEST_DIR=${HOME}/dest

cd ${SRCE_DIR}

for FILE in `ls -1A *.CLIpm`
do

  if [ ! -f ${DEST_DIR}/${FILE} ]
  then
    echo 'Transferring file: '${FILE}
    cp "${FILE}" "${DEST_DIR}/${FILE}"
    echo 'Transfer completed.'
  else
    echo 'The file: '${FILE}' already exists in '${DEST_DIR}'.'
  fi

done
