how to TAR up archived logs and then GZIP it together in a single unix command?

hi guys,

I must apologize for raising this qn here as it might not b too relevant...but I am running into space contraints and I am trying to tar my archived logs and then gzip it at one go without running the command twice ?? and restoring the file likewise in a single command??

anyone can help?

many thanks in advance :)

why not just gzip the files, how will tar save you any space?

1. tar to stdout and gzip through a pipe
2. setup a named pipe and gzip through it

Just to expand on what Jeff has said, I believe the following should work:

Code:

---

tar cvf - $ORACLE_BASE/admin/$ORACLE_SID/arch/*.arc | gzip > arch.tar.gz

---

yes!! bingo!! that's wat i needed! thanks! :))

hacketta,

..in the reverse way...how can i gunzip and then untar the *.tar.gz files?? i must admit that I am not too gd at unix command manipulation...


thanks in advance.

gunzip "file" | tar xvf -

hi davey23uk,

i hv tried ur method...the cmd run w/o any error but the *.tar.gz becomes *.tar after the run w/o untar the *.tar at all...wondering y???

hmm, ive used that command lots of time - try guncip -c at the start instead

Code:

---

gunzip < file.tar.gz | tar xvf -

---

or with GNU tar

Code:

---

gtar xvzf file.tar.gz
