I see how to pipe stuff together using Node.js streams, but how do you pipe multiple scripts together using the Unix | , given that some of these scripts can be async? $ ./a.js | ./b.js Example: a.js (chmod 0755) #!/usr/bin/env node setTimeout(function(){ console.log(JSON.stringify({ foo: 'bar' })); }, 10); b.js (chmod 0755) #!/usr/bin/env node console.log(process.argv); This is the output: $ ./a.js | ./b.js [ 'node', '/Users/viatropos/tests/b.js' ] events.js:72 throw er; // Unhandled 'error' event ^ Error: write EPIPE at errnoException (net.js:883:11) at Object.afterWrite (net.js:700:19) At

I have tried both s3cmd : $ s3cmd -r -f -v del s3://my-versioned-bucket/ And the AWS CLI: $ aws s3 rm s3://my-versioned-bucket/ --recursive But both of these commands simply add DELETE markers to S3. The command for removing a bucket also doesn't work (from the AWS CLI): $ aws s3 rb s3://my-versioned-bucket/ --force Cleaning up. Please wait... Completed 1 part(s) with ... file(s) remaining remove_bucket failed: s3://my-versioned-bucket/ A client error (BucketNotEmpty) occurred when calling the DeleteBucket operation: The bucket you tried to delete is not empty. You must delete all versions in

I have multiple npm projects saved in a local directory. Now I want to take backup of my projects without the node_modules folder, as it is taking a lot of space and can also be retrieved any time using npm install . So, I need a solution to delete all node_modules folders recursively from a specified path using the command line interface. Any suggestions/ help is highly appreciable. Darius M. Print out a list of directories to be deleted: find . -name 'node_modules' -type d -prune Delete directories from the current working directory: find . -name 'node_modules' -type d -prune -exec rm -rf '{

I'm wondering if there's a way to avoid having to type the word git at the beginning of every Git command. It would be nice if there was a way to use the git command only once in the beginning after opening a command prompt to get into "Git mode" . For example: git> After which every command we type is by default interpreted as a Git command. In a way similar to how we use the MySQL shell to write database commands: mysql> This will save me from having to type git hundreds of times a day. NOTE: I'm using git-bash , on Windows. You might want to try gitsh . From their readme: The gitsh program

This is simplest example running wget: wget http://www.example.com/images/misc/pic.png but how to make wget skip download if pic.png is already available? plundra Try the following parameter: -nc , --no-clobber : skip downloads that would download to existing files. Sample usage: wget -nc http://example.com/pic.png Daniel Sokolowski The -nc , --no-clobber option isn't the best solution as newer files will not be downloaded. One should use -N instead which will download and overwrite the file only if the server has a newer version, so the correct answer is: wget -N http://www.example.com/images

I've seen a Mac OS X git demo online in which it's configured to have multiple colors. For example, his prompt is amber, his ls directory is purple and his git diff output has ~ 4 colors (pink, light green, red, pale yellow). Can you tell me how can I configure Mac OS X terminal to achieve that? It's definitely Mac OS X Terminal.app, not iTerm. phloopy William Purcell's answer only enables color for the 'git diff' command. Do this to enable colors for all git commands: $ git config --global color.ui true William Pursell To display color in the output of git diff, you need to configure git. Try
