Extracting into a remote directory

Shell Programming and Scripting
1

I need to fit in a module in my Korn Shell script which would extract file_archive.tar.gz residing in the folder /apps/Test of my local machine into a folder /global/ in a remote machine server1.

Please help me on this regard.

Thanks
Kumarjit.

Kumarjit, this really depends on the OS and way the remote directory is accessed.

For instance if you mount a remote windows box, I strongly recommend using gvfs to mount the remote local directory and file roller to decompress.

If it is a unix box, there are a few options. One would be to simply mount the remote file system.

In my example I create a directory underneath my operational directory, the directory is called "remote".
Next ..

echho 'test' > test.txt
tar -pczf name_of_your_archive.tar.gz test.txt
ls
name_of_your_archive.tar.gz  remote  test.txt

If the objective is to now deflate into remote...

cd remote
tar -zxvf ../name_of_your_archive.tar.gz
ls
test.txt

If it is not locally mounted you can use still other approaches.

If you are going from/to a *nix type os, you could do something like this to transfer the file and untar it:

#!/usr/bin/ksh
# script: example_scp_ssh.sh

# Transfer file to remote
scp -v -o IdentityFile=~/.ssh/id_rsa -o BatchMode=yes /apps/Test/archive.tar.gz user@remote:/global
rc=$?
if [[ $rc != 0 ]]    then
    print "***Error occurred transferring file...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
else
 print "***Successful transfer of file...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
fi

# Run cmd on remote
ssh_results=`ssh user@remote '. ./.profile;tar -zxvf /global/archive.tar.gz'`
print "${ssh_results}"
