Just put all the commands in one script, for example:
#!/bin/sh
backup1 &&
backup2 &&
backup3
Then run "sudo /the/backupscript". If it's in a directory in your PATH,
you can simply do "sudo backupscript".
Of course, your example is so entirely obfuscated and genericized that
it's meaningless. You can't even demonstrate anything with it.
Here's the backup script I use at home, with only one piece of information
hidden. It's not elegant. It's simply what I've got.
It is named /usr/local/bin/backup. When I want to run it, I type
"sudo backup".
#!/bin/bash
cd /backup || exit
today=$(date +%Y%m%d)
if [ -e /hd/.hd ]; then
( cd / && rsync -av --delete etc home usr/local /hd/titan/ )
( cd /stuff && rsync -av --delete * /hd/ )
else
echo "/hd not mounted"
fi
( cd /etc && find . -print0 |
cpio -o -0 | gzip > "/backup/compress/backup.$HOSTNAME.etc.$today" )
( export RSYNC_RSH='ssh -p [REDACTED]';
cd remote && rsync -av --delete r...@remote.wooledge.org:{/etc,/var/moin} . )
( cd remote && find . -print0 |
cpio -o -0 | gzip > "/backup/compress/backup.remote.$today" )
( cd /home && find . \( -type d -name .cache \) -prune -o -print0 |
cpio -o -0 | gzip > "/backup/compress/backup.$HOSTNAME.home.$today" )
find compress -type f -mtime +4 -delete
( cd compress && mkisofs -o ../image . )
ls -ld image
read -p "Write to DVD? [y] " yn
case $yn in ''|[Yy]|[Yy]es) : ;; *) exit ;; esac
cdrecord -v image
