how to use ctrl-D in a shell script

Question

Hi Everyone,

I have a bash shell script that requires ctrl-D to break out of the terminal.can anyone tell me how to use it in the shell script

example

ssh host last --->displays the list of users who were logged on to that host

i have different hosts the output is appended to one final and when i'm executing this particular shell script along with other series of commands, i'm using ctrl-D to see the output

suppose my shell script is myscript.sh to execute myscript.sh

./myscript.sh

ctl-D

connection to host closed

output is displayed

instead i want to use ctrl-D in my script file

Any ideas on this are appreciated.

Thanks,

Answer 1

There is no way to do this directly. Use a heredoc to feed stdin instead.

./someprog.sh << EOF
something here
EOF

Answer 2

#! /bin/sh
echo 'Enter one line at a time'
echo 'Press CTRL+D to finish'
cat >test.out
echo 'OK'

Answer 3

Why don't you tell last how many lines you want to see? Then you won't have to interrupt it with a Ctrl+D. For example, to see 10 lines use:

ssh hostname "last -10"
