This way you can get stats from your logs but this method is a little bit rudimentary as you are going to get visits from crawlers, bots,… that are not real visits. Parse your logs directly with awk.
#!/bin/sh
echo 'Number of unique visitors'
cat /var/log/apache/www.yoursite.com-access.log |awk '{print $1}' | sort | uniq | wc -l
echo 'Ip of unique visitors'
cat cat /var/log/apache/www.yoursite.com-access.log |awk '{print $1}' | sort | uniq | wc -l |awk '{print $1}' | sort | uniq
Usefull script to check if a proxy is alive.
#!/bin/bash
# HTTP Proxy Server's IP Address (or URL)
proxy_server=$1
# HTTP Proxy Server's Port Number
port=$2
# We're trying to reach this url via the given HTTP Proxy Server
# (http://www.google.com by default)
url="http://www.google.com"
# Timeout time (in seconds)
timeout=20
# We're fetching the return code and assigning it to the $result variable
result=`HEAD -d -p http://$proxy_server:$port -t $timeout $url`
# If the return code is 200, we've reached to $url successfully
if [ "$result" = "200 OK" ]; then
echo "1 (proxy works)"
# Otherwise, we've got a problem (either the HTTP Proxy Server does not work
# or the request timed out)
else
echo "0 (proxy does not work or request timed out)"
fi
Maybe it’s no longer working
#!/bin/bash
# Google url shortener bash script

What this script does is, check the gateway mac address to find out if you are within your lan or in a different place. If at home, mount a share as normal. If away, mount that share as a ssh file system.
#!/bin/bash
gateway=$(ip route show 0.0.0.0/0 | awk '{print $3}')
mactest=$(arp -n -a $gateway | awk '{print $4}')
targetmac="XX:XX:XX:XX:XX:XX"
homeup="mount -t cifs -o username=USER,password=PASSWORD //SERVER/SHARE /mnt/remote"
awayup="sshfs my.dyndns.tld:/path/to/share /mnt/remote"
down="umount -l /mnt/remote"
if [ $mactest==$targetmac ]
then
case "$2" in
up)
$homeup
;;
down)
$down
;;
esac
else
case "$2" in

You should run this command within a script!
abspath="$(cd "${0%/*}" 2>/dev/null; echo "$PWD"/"${0##*/}")"
Dirty script to find out free storage space.
for path in `mount | awk '/^\/dev/ {print $3}'`; do df -h "$path"; done;
With this script you can check if an argument to a script is numeric, char or alphanumeric.
[[ -z "$1" ]] && echo "I cant work without an input" && exit 1
INPUT="$@"
[[ "$INPUT" == ?(+|-)+([0-9]) ]] && echo "$INPUT is numeric" && exit 0
[[ "$INPUT" == +([a-zA-Z]) ]] && echo "$INPUT is character" && exit 0
[[ "$INPUT" == *([0-9]|[a-zA-Z])* ]] && echo "$INPUT is alpha-numeric" && exit 0
An gdialog example in linux. A dialog prompt for yes or no.
