cannot create /dev/tcp/localhost/5744

[jambel]

Hi,

I have an application that listens to port 5744. I send to it a command from a terminal like this

echo my-command > /dev/tcp/localhost/5744

and replies

I need to built a script doing the job so I make one as simple as this

#!/bin/sh

# $1 = command
# $2 = hostname
# $3 = port

echo $1 > /dev/tcp/$2/$3

then in terminal I write..

sh myscript.sh command localhost 5744

and I come up with this error

cannot create /dev/tcp/localhost/5744: Directory nonexistent

Any ideas?

The functionality you're trying to use is available in bash, not the POSIX shell, so you need '#!/bin/bash', not '#!/bin/sh'. Try running your existing script with "bash myscript.sh ...". If that works, then just change the "#!" line and it should be fine.
