How can I echo / dev / tty?

Question

Is there a way to send something like "end of data" after execution

echo "test" > /dev/tty1

to get the "input cursor" back to the "receiving" terminal (in this case tty1)?

Answer 1

Using echo > /dev/tty , you cannot achieve this. But you can do this by sending a signal to the process that this tty uses.

For example:

 kill -s SIGINT `ps -ft pts/2 | grep pts/2 | cut -d ' ' -f 5` 

Answer 2

You cannot do that. The redirection operator '>' makes it so that the echo command is used for standard WHOLE time input, and you cannot just change it later.

You might want to rethink your needs and implementation.

Answer 3

 $ echo "test" > /dev/tty test 

  Cygwin supports the following character devices commonly found on POSIX systems:

 / dev / tty The current controlling tty of a session.

Special filenames

Answer 4

centos will print your line in the console of your choice
