lxc exec

Execute commands in instances

Synopsis

Description: Execute commands in instances

The command is executed directly using exec, so there is no shell and shell patterns (variables, file redirects, …) won’t be understood. If you need a shell environment you need to execute the shell executable, passing the shell commands as arguments, for example:

lxc exec <instance> -- sh -c "cd /tmp && pwd"

Mode defaults to non-interactive, interactive mode is selected if both stdin AND stdout are terminals (stderr is ignored).

lxc exec [<remote>:]<instance> [flags] [--] <command line>
