gzip instead of compress
Duplicate threads merged jmc

Hi,

I have a script wherein I want to use gzip instead of compress.
# cat dly_appsfiles_bkp.ksh
#
# dly_appsfiles_bkp.ksh
#
date_stamp=`date +%m%d%y`
base_dir=/u05/gld1
sub_dir=apps
bkp_dir=/u00/backup/GLD1/APPS
bkp_file_name=${sub_dir}_${date_stamp}.tar.Z
echo ""
echo "Starting Compressed Apps Files backup ..."
echo "Compressed backup file name: ${bkp_dir}/${bkp_file_name}"
echo ""
cd ${base_dir}
tar cvf - ${sub_dir} | compress > ${bkp_dir}/${bkp_file_name}
echo ""
cd $bkp_dir
ls -ltr *.Z
mailx -s "Done" abc@abc.com<<EOF
Backup done
EOF
echo ""
echo "Done."
echo ""

I'm new to shell scripting.Can someone please help me on how this can be modified?

Thanks,

Have not tested this but it should work. Change
Code:
bkp_file_name=${sub_dir}_${date_stamp}.tar.Z
to
Code:
bkp_file_name=${sub_dir}_${date_stamp}.tgz
and
Code:
tar cvf - ${sub_dir} | compress > ${bkp_dir}/${bkp_file_name}
to
Code:
tar cvzf - ${sub_dir} > ${bkp_dir}/${bkp_file_name}
and
Code:
ls -ltr *.Z
to
Code:
ls -ltr *.tgz

change to this
Code:
tar cvf - ${sub_dir} | gzip - > ${bkp_dir}/${bkp_file_name}.gz
Also some versions of tar support "tar zcvf" wghich also uses gzip compression to compress the file. Check your tar man page.
Code:
tar zcvf - ${sub_dir} > ${bkp_dir}/${bkp_file_name}.gz

Hi,

The size of the backup file is 0 bytes.
Its not copying any files for backup.

-rw-r--r-- 1 appldev1 dba 0 Jun 29 08:34 oraInventory_062909.tgz

This is on AIX.

Regards,
Narayan

tar zcvf - ${sub_dir} > ${bkp_dir}/${bkp_file_name}.gz does not seem to be working on AIX.
Please suggest.

Regards

First check that your version of tar supports the -z option i.e. man tar.

If it does, try the following
Code:
tar zcvf ${bkp_dir}/${bkp_file_name}.gz ${sub_dir}
