Reading input files
Okay, so I've looked on here and found some similar things, but not exactly what I am looking for. I am working on creating a script that can back up some files, based on the contents of another file - the configuration file.
First file contains the files to back up - we'll call this backup.conf:
(Format of file: SERVICE:/path/to/file:destination)
ETC:/etc/hosts:./etc
ETC:/etc/netmasks:./etc
DHCP:/etc/default/dhcp:./etc
The next file is the backup script. It contains an "awk" statement to break down the backup.conf file so that it only needs to gather specific parts, based on what needs to be backed up. We'll call this backup:
#awk statement - creates temporary file with targets and destinations
sed '/^ *#/d;s/#.*//' backup.conf | grep -v ^$ | grep ETC | awk -F: '{print $2" "$3}' >! /tmp/backupfiles
#while loop to process output
while read line
do
if [ -f $line ]
then
/usr/bin/cp $line $target
fi
done < /tmp/backupfiles
I realize that $target is not set here. This is the problem that I am running into, and this is just to give you an idea of what I am attempting to do. Basically, the while statement needs to be able to take each line from /tmp/backupfiles and as it reads it, break it down into two variables, the file to back backed up ($line) and the location to back it up to ($target). Using $line is can also verify that the file exists and is available before trying to back it up.
Any suggestions? I am using "ksh" for this on Solaris systems.

LEARN ABOUT NETBSD
virecover
VIRECOVER(8) BSD System Manager's Manual VIRECOVER(8)
NAME
virecover -- report recovered vi edit sessions
SYNOPSIS
/usr/libexec/virecover
DESCRIPTION
The virecover utility sends emails to users who have vi(1) recovery files.
This email gives the name of the file that was saved for recovery and instructions for recovering most, if not all, of the changes to the
file. This is done by using the -r option with vi(1). See the -r option in vi(1) for details.
If the backup files have the execute bit set or are zero length, then they have not been modified, so virecover deletes them to clean up.
virecover also removes recovery files that are corrupted, zero length, or do not have a corresponding backup file.
virecover is normally run automatically at boot time using /etc/rc.d/virecover.
FILES
/var/tmp/vi.recover/recover.* vi(1) recovery files
/var/tmp/vi.recover/vi.* vi(1) editor backup files
SEE ALSO
vi(1), rc.conf(5)
HISTORY
This script, previously known as recover.script, is from nvi and was added to NetBSD in 1996. It was renamed in 2001.
