thanks for your inputs corona688. My script is getting some input parameters which helps it to find the file names and then lists all the files with specific names and gunzip and tars them to an archive folder. Timestamp is added as part of the tar-red file name to have an option to store multiple files on a day.

I have modified the script to do tar instead of gzip.. please find the modified script attached, I see that a .tar.gz file is created. But in order to verify that it has tar-red properly, I would like to unzip (or do what ever is required) to see the files back in its original state. Can you please help me with how to get the original files seperately?

Also, I am getting the error message below when I run the script.. can you please advice?

SCRIPT:
PHP Code:
$ cat archival.sh
#### SCript to archieve source file and tar them
#!/bin/sh
date_str=`date "+%Y%m%d%H%M%S"`
ENVID=$1
logfile=${ENVID}_archival_${date_str}.log
echo Script $0 started at `date` >${logfile}
#### Check if one parameter is received#######
if [ $# -ne 1 ]; then
echo "input parameter for the script is missing" >>${logfile} 2>&1
exit 1
fi
##### Get the ENVID and DATE_OF_RUN from the parameter file####
parmfilename=${ENVID}_parm.parm
echo $parmfilename >>${logfile}
DATE_OF_RUN=`cat $parmfilename | grep "DATE_OF_RUN" | cut -d"=" -f2`
echo $DATE_OF_RUN >>${logfile}
#cd /landing
#### List files based on input parameter####
FILE_LIST=`ls $ENVID_*_$DATE_OF_RUN.$ENVID_*.TXT`
echo "files are $FILE_LIST" >>${logfile}
for FILE in $FILE_LIST
do
#gzip -c $FILE | gzip > $FILE_$(date +"%Y%m%d%H%M%S").gz
tar -zcf ${ENVID}_$(date +"%Y%m%d%H%M%S").tar.gz /opt/informatica/infa_shared/SrcFiles/arch
done
echo "Files are zipped" >>${logfile} 
Error message:

PHP Code:
tar: Removing leading `/' from member names
tar: Removing leading `/' from member names
tar: Removing leading `/' from member names
tar: Removing leading `/' from member names 
Thanks!
