The Shell lost the inverted comma in a nested ssh command
Hi,

i want use this Comand for my psql request

Code:
sh ssh -o StrictHostKeyChecking=no rootatemailaddress.de sudo psql -U postgres -c "select pg_terminate_backend(pid) from pg_stat_activity where datnam=\'$DB\';"'"



but the shell lost the inverted comma for datnam=\'$DB\'. The request deliver datnam=DB1 but for the psql request i need datnam='DB'. Where is my mistake? The psql comand need the inverted comma left and right from the $DB variable.

vconsole.conf

VCONSOLE.CONF(5)						   vconsole.conf						  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
	   Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
	   a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
	   Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

	   KEYMAP=de-latin1
	   FONT=latarcyrheb-sun16
