I couldnt find answer to this althougth there are many similar questions.I wanted to change colour of my linux command prompt based on the remote host i have ssh to.Since bash environment variables are not preserved over ssh,so how could i do this.There are hundreds of server i login everyday.So changing /.bashrc of each remote host is not possible.is there a way i can pullout a script which can be called each time ssh is done.Can someone please give in detail of which file and how it should be edited.gnome,openssh etc are not supprted.

  • You could use something like `ssh host "PS1=$PS1 bash"`, but any configuration files on the remote end that configure `PS1` will almost certainly not check to see if `PS1` is already set. – chepner Aug 01 '16 at 14:12

during ssh execution,a new login shell was executed. during shell login the *rc files are not executed,only *profile was executed.

so place your code in /etc/profile or ~/.bash_profile.

"Since bash environment variables are not preserved over ssh..."

man ssh

 Additionally, ssh reads ~/.ssh/environment, and adds lines of the format
     “VARNAME=value” to the environment if the file exists and users are
     allowed to change their environment.  For more information, see the
     PermitUserEnvironment option in sshd_config(5).

    This only works if the server's configuration has enabled PermitUserEnvironment , which is off by default. – Barca-15 Aug 01 '16 at 15:21
