Top Forums Shell Programming and Scripting ssh, bash, and /dev/stderr: no such device Post 302428725 by jim mcnamara on Thursday 10th of June 2010 04:36:50 PM

ssh blocks input devices which are not terminals - openSSH 2.0 does this on my system:
Code:
> ssh 1.1.1.1 <<EOF
more>echo 'foo' > 2
more>EOF
Pseudo-terminal will not be allocated because stdin is not a terminal.

Generally, you have two choices:
1. sftp a shell script over to the remote; then ssh hostname shellscript.sh
2. ssh hostname [command line goes here ]

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
