Script help

Hi!

I have the following script which I am using to curl against a file which as few URLs-

#!/bin/sh

RESULT=0

# read all input from the specified file
exec <"$1"

while true
do
read SERVICE
if [ "$SERVICE" = "" ]
then
# no more services
exit $RESULT
fi

read URL
if [ "$URL" = "" ]
then
# error in service list file
echo "ERROR: no URL for service $SERVICE" >&2
exit 2
fi

echo "Testing $SERVICE: "

# adjust the options to suit your needs
curl -I $URL

if [ $? -eq 0 ]
then
echo "Success"
else
echo "Fail"
RESULT=1
fi
done

From the curl command I get a text in the html page which says ALIVE, I want to alert(email me) if the text does not contain the word ALIVE.

Please help.

Thanks,
Jack.

if [ $# -ne 2 ] ; then
  echo "usage: $0 <word> <website>"
fi

curl $2 | grep_output="$(grep $1 $2)"

LOOP=1
while [ $LOOP -eq 1 ]; do 
if [ -z "$grep_output" ]; then
    let LOOP = 1
else
    echo "WARNING!" | mail -s (subject) -c (your e-mail address)
    let LOOP=0
fi
done

This should work for what you're describing, but try it first, I'm somewhat new, and not quite sure if this will work myself
However, if this does work, then you can search for any word you want, not just "ALIVE"

Puddles, your code is not gonna work for several reasons:

curl $2 | grep_output="$(grep $1 $2)"

You're piping the output of curl into grep_output, which is not a command, and shell won't know what to do with it.
Then you end up in an infinite loop if grep_output is empty.

LOOP=1 
while [ $LOOP -eq 1 ]; do  
  if [ -z "$grep_output" ]; then     
    let LOOP = 1

How's this?

#!/bin/sh
while read SERVICE URL ; do 
   [[ "$URL" = "" ]] && echo "ERROR: no URL for service $SERVICE" >&2 && exit 2
   echo "Testing $SERVICE: "   
  # adjust the options to suit your needs
   curl -I $URL | grep ALIVE  
   if [ $? -eq 0 ] ;then
      echo "ALIVE found"
   else
     echo "Nobody alive" | mail -s subject me@somedomain.dom
   fi
done < $1

Thanks Mirni,

Here is the code I have come up with -

#!/bin/sh

OP=0

exec <"/fs1/ainuser/ain/user-1/list"

while true
do
        read APP
                if [ "$APP" = "" ]
                then
                        exit $OP
                fi

        read URL
                if [ "$URL" = "" ]
                then
                        echo "ERROR no URL defined for $APP" >&2
                        exit 2
                fi

        sleep 3

        echo "Checking $APP: "
        curl $URL |grep -q -i alive
        x=$?
                if [ ${x} -eq 0 ]
                then
                        echo "App is alive : `date`"
                else
                        echo "$APP is down in env-1" | mail -s "$APP is down in env-1" testalert@email.com
                fi
done

Now I want to test the viability of the URL atleast 6 times with 3 seconds intervals and if it fails 4 times out of 6 then send the email.

I am really struggling on this one.. please help!!

Thanks,
Jack.
