echo "show run"
the above commands gives input to terminal of router and then displays output on terminal. i want the output of this specific command to be redirected to the file. please help me

man bash /Redirecting Output
echo "show run" > filename
Anything similar to this will redirect this text "show run" to the file and not the output of router.

???
show run > file
please be more precise about the context.
what's the router?
what OS?
what shell?
...
(
echo open x.x.x.x
sleep 2
echo "usrname"
sleep 1
echo "pass"
sleep 1
echo "sh run | s pim "
sleep 1
echo 'sh run | i hostname'
sleep 1
echo "sh ip int br | i Loopback"
sleep 1
echo "sh inv | i SN"
sleep 1
echo "logout"
sleep 1
) | telnet
Above is the simple telnet program.
I'll try to explain the problem.
Here the echo command is used to pass the commands to router console and not to print the text. So whenever i use redirection for particular line in this program, it redirects the command itself and not the output which router will give.

sorry, I don't have experience with telnet.
subshell can be avoided using a list :
{
command1
command2
} | command >file
are all those echo useful? you could use a here-doc
telnet <<EOF >file
open x.x.x.x
sleep 2
usrname
sleep 1
pass
sleep 1
sh run | s pim
sleep 1
sh run | i hostname
sleep 1
sh ip int br | i Loopback
sleep 1
sh inv | i SN
sleep 1
logout
sleep
EOF
