var nodemiral = require('nodemiral');
var session = nodemiral.session('hostname', {username: 'root', password: 'password'});

  • ssh - object whose key and value will be passed as -o key:value to any ssh session. For example { 'StrictHostKeyChecking': 'no', 'UserKnownHostsFile': '/dev/null' }

execute given shell command on the remote server

@param shellCommand - shellCommand
@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.execute(shellCommand, callback);

@param localScriptFile - localScriptFile
@param options.vars - variables to the template if uses ejs in the script
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.executeScript(localScriptFile, options, callback);

copy a file from local machine to the remote machine. Supports binary files too. Support EJS templating with non-binary files

@param localFile - localFile
@param remoteFileLocation - remoteFileLocation
@param options.vars - templateVars
@param optiosn.progressBar - show progress bar
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.copy(localFile, remoteFileLocation, options, callback)
