[SOLVED] grunt rpm create a symlink

Issue

I have this grunt file that creates a rpm package for me, how can I create a symlink like this for an example:

link("/usr/local/bin/tams-cli", "/opt/tams-cli/tams-cli.js")

Have not been able to to find that, here below is my source code.

grunt.initConfig({
    pkg: grunt.file.readJSON('./package.json'),
    easy_rpm: {
      options: {
        buildArch,
        rpmDestination: './built/',
      },
      release: {
        files: [
          {
            src: ['node_modules/**/*',
              'js/**/*',
              'cfg/*',
              'package.json',
              'readme.md',
            ],
            dest: '/opt/tams-cli',
          },
          {
            src: 'tams-cli.js',
            dest: '/opt/tams-cli',
            mode: 0550,
          }
        ],
        excludeFiles: [
          'tmp-*',
          './built',
        ],
      },
    },

Solution

To create the symlink after the rpm package is installed utilize the postInstallScript option in your easy_rpm task. The description for the postInstallScript reads:

postInstallScript

Array<String>

An array of commands to be executed after the installation. Each element in the array represents a command.

In the Gruntfile.js excerpt below it utilizes the ln command to create the symlink using the additional two options:

• -s to make a symbolic link instead of a hard link.
• -f to remove existing destination files if they exist already.

Gruntfile.js

grunt.initConfig({
  // ...
  easy_rpm: {
    options: {
      postInstallScript: ['ln -s -f /opt/tams-cli/tams-cli.js /usr/local/bin/tams-cli'],
      // ..
    },
    // ...
  },
  // ...
});
