UNIX for Dummies Questions & Answers

Hi,

I would like to have a combined gzip and tar that will compress and create multiple output tar.gz files. I want to have multiple files output because i cannot create an archive because there is no more space on my harddisk. I cannot transfer it locally because of slow connection. I want to have a script that once it reached the maximum limit (e.g.100MB), it will prompt me to create a new file.

Anyone can help?

thanks,

btw, i already did this

$tar cvf - filename.xxx |gzip > filename.tar.gz

What do you mean by multiple file output? Do you want multiple tar.gz files ?

Code:

I cannot transfer it locally because of slow connection. I want to have a script that once it reached the maximum limit (e.g.100MB), it will prompt me to create a new file.

Do you want to create a new tar.gz file once the current tar.gz file has reached the size of 100MB?

Please answer my queries and may be i can help.

Here is the scenario:

1. I have a 5.7 GB log which i want to archive. However, my problem is the hdisk has no more space available.

Solution i want to have :

a. create a backup of the file through tar/gzip command but will have a limit of 100MB/file or depending on the maximum limit i will set. It will prompt me that it reached the limit. From there, i can transfer the first file to my local machine and continue creating the next file gz.

#!/bin/ksh

LOGDIR=/home/XXXX
ARCHIVE_NAME=/tmp/archive.tar
MAX_ARCHIVE_SIZE=XXX # your choice

tar -cvf ${ARCHIVE_NAME}

for FILENAME in `ls -lrt ${LOGDIR}|awk '{print $9}'`
do
gzip ${FILENAME} 2>/dev/null
tar -rvf ${ARCHIVE_NAME} ${FILENAME}.gz 2>/dev/null
rm -f ${FILENAME}.gz 2>/dev/null
SIZE=`ls -l ${ARCHIVE_NAME} | awk '{print $5}'`
if [[ "${SIZE}" >= "${MAX_ARCHIVE_SIZE}" ]]
then
move_delete_file; # function to move and delete the archive from LOGDIR
fi
done
