I keep getting this error message running this script. What is causing it?
Line 18 is the last line in the file which I think is a CR.

./Boa404Chk.sh: line 18: syntax error: unexpected end of file


#!/bin/bash

if diff /var/log/boa/access_log /etc/boa_access_bkp >/dev/null
then
exit 0
else
cat /var/log/boa/access_log > /etc/boa_access_bkp
if grep -q '404' '/var/log/boa/access_log'
then
sed 's/404$/===404===/g' '/var/log/boa/access_log > /etc/boa_access_bkp
cd
cat /etc/boa_access_bkp | mail -s "BOA 404 in access_log" me@myisp.net &> /dev/null
cat /etc/boa_access_bkp >> boa_access_dttlbkp #save to send at EOD
cat /dev/null > /var/log/boa/access_log
cat /dev/null > /etc/boa_access_bkp
fi
fi

Please try using elif instead of else .

Please use the CODE tags when posting scripts...makes things much easier to read. And you're missing the closing single-quote from line 10, after the /var/log/boa/access_log...fixing that seems to fix the script.
Would help if you said WHERE to use it, and WHY. Can you post the example code of what you're suggesting?

Thanks. The missing single quote fixed it. I noticed the auto left shift of the script. I guess you just put Code: before a script to correct this?
