Top Forums Shell Programming and Scripting Read several variables from command output via SSH Post 303039935 by RudiC on Friday 18th of October 2019 04:29:34 AM

Does lshwres interact directly with the terminal? Are there any options to disable this? I could sort of replicate the situation with stty:
Code:
ssh -n -t user@remotehost "hostname; stty"
Pseudo-terminal will not be allocated because stdin is not a terminal.
remotehostname
echo $?
0

No error!


Looks like -n and -t are mutually exclusive (which seems logical if reading the man page). Try dropping the -n:
Code:
ssh -t user@remotehost  "hostname; stty"
remotehostname
speed 38400 baud;
.
.
.
echo $?
0

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
