Solaris

I want to incorporate this in a script for some simple monitoring for my webserver

telnet localhost 80
GET /opencms/opencms/test/index.html


how to do it?

I tried

echo "GET /opencms/opencms/test/index.html" | telnet localhost 80

I tried

telnet localhost 80 << EOF
echo "GET /opencms/opencms/test/index.html"
EOF

I tried

"GET /opencms/opencms/test/index.html" < telnet localhost 80

all won't work, I need some help

You're better off using wget, curl or even using a proper monitoring tool like Nagios with the check_http plugin.

That aside, you can do simple things with expect, e.g.

Code:

#!/usr/bin/expect -f

set timeout 10
spawn /usr/bin/telnet myhost 80
expect "Escape"
send "GET /\r"
expect "something here"

Code:

#! /usr/bin/ksh
exec 4>&1 5>&2
telnet foo 80 >&4 2>&5 |&
print -p GET

thx zazzybob,

My requirement is quite complex

hey reborg,

yur script dun work. what is "4>&1" "5>&2" supposed to do?

#!/usr/bin/ksh
exec 4>&1 5>&2
telnet localhost 80 1>&4 2>&5 | &
print -p GET

#ksh -x /tmp/saver
+ exec
+ 4>& 1 5>& 2
/tmp/saver[3]: syntax error at line 4 : `&' unexpected

It didn't work because you didn't copy it correctly.

Look at where I have spaces in my post and what you have.

exec 4>&1 5>&2

duplicates the output streams 4 and 5 to stdout and stderr.
