Need help with error checking
I am creating a script that will automatically use sftp to connect to a site and download a file, extract the tar and then delete the tar file once completed.
What I am stuck on is the error checking for this process.
Here is the code so far:
Quote:
#!/bin/bash
cd /usr/local
sftp -b ftpbatch root@192.168.0.199
## ftpbatch changes the dir and gets the tar file
tar -xvf *.tar
rm -rf *.tar
Now this works for me as is, but i need error checking for 2 points.
1 for the ftp connection to wait 2 minutes and retry if there is no connection and to spawn off a yellow warning message to an email address at 10 minutes and a red warning message at 20. After 20 minutes the script dies.
The second message which i may or may not need, is one to monitor the tar output for any error messages. This is not as important as the first one however.
Any suggestions or help will be appreciated!
Thank you

virt-tar-out
virt-tar-out(1) Virtualization Support virt-tar-out(1)
NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball.
SYNOPSIS
virt-tar-out -a disk.img /dir files.tar
virt-tar-out -d domain /dir files.tar
virt-tar-out -d domain /dir - | gzip --best > files.tar.gz
DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball.
The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to
write to standard output.
EXAMPLES
Download the home directories from a guest:
virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial
copy, you are probably better off using guestfish directly.
OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.
SEE ALSO
guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), <http://libguestfs.org/>.
