Hi I am trying to learn shell script and i ran into an issue.
I am trying to read a file with few directories and tar them up.
I used a while loop but i end up overwriting tar file with only the last directory in the file being tared .
cat test.txt |
(
while read line
do
tar -czPf backup.tar.gz $line
done
)
Every time the loop runs, it creates the tar file in the same name (backup.tar.gz) thus over writing the previous one, hence it ends up only with the last tared file.
The tar command in your while loop should have variable for both source and destination.
Try this:
cat test.txt |
(
while read line
do
tar -czPf backup_$line.tar.gz $line
done
)
