rcmd
Remote command invocation tool.
Usage
Let us assume that we want to invoke ls -l
command on the remote machine. Using rcmd
one may do that in two different, but similar, ways:
- Type in local machine command prompt
rcmd ls -l
and hit enter. - Change the name of
rcmd
executable file torcmd-ls
(pay attention to the dash) and after that typercmd-ls -l
(remember about the dash) and hit enter.
It should be noted that the second method may be useful in some cases, e.g. if some other application needs to invoke some command remotely.
In most cases configuration file .rcmd.yaml
will be needed (described in the Configuration section).
Configuration
Configuration file, named .rcmd.yaml
, may be located in the local machine working directory of executed command.
Syntax is imposed by the YAML format.
File is divided into two main sections:
global
- section conataining options for all commands,command
- section for options for particular commands.
Supported options
user
- user name,host
- host name,port
- port number,cd
- directory to change to,env
- set environment variables (remember aboutAcceptEnv
)map
- map command to the new value,verbose
- switches on verbosity.
All of the above options can occur in both sections (global
and command
followed by command name).
