Error 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

gpodder-backup

GPODDER-BACKUP(1)						   User Commands						 GPODDER-BACKUP(1)

NAME

       gpodder-backup - Backup and restore utility for gPodder user data

SYNOPSIS

       gpodder-backup [--create|--extract] <archive.gpo.tar.gz> [options] gpodder-backup --purge

DESCRIPTION

       This utility can be used to create a dump of the current gPodder data (configuration files + downloads), optionally replacing the real con-
       tents of the download folder with zero-byte files (for submitting your data to a bug report without having to transfer lots of data).

OPTIONS

       --version
	      show program's version number and exit

       -h, --help
	      show this help message and exit

       -c <FILE>, --create=<FILE>
	      Create a new archive

       -x <FILE>, --extract=<FILE>
	      Extract an existing archive

       -f, --fake-downloads
	      Store downloads as zero-byte files in backup

       -n, --no-covers
	      Do not include cover files in archive

       -D <DIR>, --destination=<DIR>
	      Extract downloads in different folder

       -P, --purge
	      Remove current data (can be combined with --extract)

USAGE FOR BUG REPORTING

       This command is useful if you want to report a bug in gPodder:

       gpodder-backup --create bug123.gpo.tar.gz --fake-downloads
	      Backup your current data to file bug123.gpo.tar.gz, but don't store download data (create zero-size dummy files  instead).  You  can
	      then attach bug123.gpo.tar.gz to the bug report.

       If you are instructed to try gPodder from a "clean state", you can use the following command (be sure to backup your data before!):

       gpodder-backup --purge
	      Remove all gPodder data, so you can start from a clean state

EXAMPLES

       gpodder-backup --create today.gpo.tar.gz
	      Backup your current data to file today.gpo.tar.gz

       gpodder-backup --extract mybackup.gpo.tar.gz
	      Restore (without purging) the contents of mybackup.gpo.tar.gz

       gpodder-backup --extract default.gpo.tar.gz --purge
	      Remove current data, then restore the contents of default.gpo.tar.gz

       gpodder-backup --purge
	      Remove all gPodder data, so you can start from a clean state

EXTRACTING FAKED DOWNLOADS

       Please  note  that  any	existing  downloads will be overwritten with zero-byte files when using the --extract option of the gpodder-backup
       utility with a backup created with --fake-downloads
