Hello everyone,

My company has several servers and we want to backup the production web servers to a dedicated server box. I have written a backupscript that I wanted to use but I got a slew of errors. Here is the script:

#!/bin/bash

TODAY=\"date +%D\"
TODAY2=\"date +%m%d%Y\"
EMAIL=\"backupadmin@domain.com\"
BACKDIR=\"/root/backup\"
MYSQLUSR=\"root\"
MYSQLPSD=\"999999\"
DB=\"--alldatabases\"
FILE=\"server_backup\"
CHK=\"chkrootkit\"
RKH=\"rkhunter\"

cd $BACKDIR
mysqldump -u $MYSQLUSR -p $MYSQLPSD $DB > $FILE_$TODAY2
rkhunter -c > $RKH_$TODAY2
cd /root/chkrootkit-0.45/
./chkrootkit > $BACKDIR/$CHK_$TODAY2
cd $BACKDIR

tar czf $FILE_temp_$TODAY2.tar.gz $FILE_$TODAY2 $RKH_$TODAY2 $CHK_TODAY2 /home | gpg -c > $FILE_$TODAY2.tar.gz
rm $RKH_$TODAY2
rm $FILE_$TODAY2
rm $CHK_$TODAY2
rm $FILE_temp_$TODAY2.tar.gz

date | mutt -s \"$FILE ($TODAY) \" -a $FILE_$TODAY2.tar.gz $EMAIL

When I run the script, using ./script.sh I get the following set of errors:

[root@localhost ~]# ./script.sh
./brawn_daily_bckup.sh: line 3: +%D": command not found
./brawn_daily_bckup.sh: line 4: +%m%d%Y": command not found

What I am trying to do is to run Rkhunter and Chkrootkit and give them their own text file. Then make a mysql backup and a backup of the home directory. All these files get tarred then encrypted. All files that were used prior are then deleted.

Can someone please tell me what I did wrong? Any help will be greatly appreciated.

TO fix the erros for those, remove the '/' from variables and use ' (single quotation) instead of " (double quotation marks).

your biggest problem seems to be quoting, why are you escaping the quotes when assigning the variables values? You need the quotes to escape the special shell characters. You also should be using single quotes otherwise some of the shell characters might still be interpreted.


Here is some shell output to illustrate the point


shaitan@mike:~> TODAY='date +%D'
shaitan@mike:~> echo $TODAY
date +%D
shaitan@mike:~> TODAY=\"date +%D\"
bash: +%D": command not found

So is this what it should say?

TODAY='date +%D'
TODAY2='date +%m%d%Y'
EMAIL='backupadmin@domain.com'
BACKDIR='/root/backup'
MYSQLUSR='root'
MYSQLPSD='999999'
DB='--alldatabases'
FILE='server_backup'
CHK='chkrootkit'
RKH='rkhunter'

Looks good at a glance. If there are any other errors in your script the errors will probably make a lot more sense now. I did not see any at a glance.
