- How to create a tar + gzip from a listing of file names.
- Posted by Daryl Rose on January 24th, 2007
I have a file with about a dozen file names in it. I want to create a
tar/gzip of those files.
Currently I have it written this way:
CNT=0
while read line
do
if [ $CNT -eq 0 ]
then
tar cvf BKUPTST_$DATE.tar $line
CNT=1
else
tar rvf BKUPTST_$DATE.tar $line
fi
done < $APP_PATH/$APP/$DB/archive.lst
gzip BKUPTST_$DATE.tar
This works, but I would like to find a better way to do this. BTW, this
is Unix tar, not a GNU tar. If it were GNU, then I know there are
options to read in from a file and compress all in one step.
Anyone have any idea's?
Thank you.
Daryl

Daryl Rose :
tar cvf BKUPTST_$DATE.tar $(sed 's/\n/ /g' < archive.lst)

file should contain nothing but the names, one to a line, preferably
without a leading /.
If your tar doesn't have a -I option, consider:
tar cf - ` cat file ` | ...
which will work as long as the number/character-count of the files
does not blow the shell buffer.

$(....) splits upon space, tabs and newlines by default and also
expands the wildcards. So you don't need to convert newlines to
spaces. You should rather make sure $(...) only splits on
newlines, and doesn't expand the wildcards:
IFS='
'
set -f
