# Analizo::Command::metrics\_batch(3pm)

processes several source code directories in batch

## NAME

analizo-metrics-batch - processes several source code directories in batch

## USAGE

```
  analizo metrics-batch [OPTIONS] [<input> [<input> ...]]
```

## DESCRIPTION

Processes several source code directories in batch running **analizo metrics** for each and optionally consolidating the results in a single data file.

**analizo metrics-batch** is useful when you want to analyze several projects at once, or several different versions of the same project. You pass a list of directories in the command line and each one will be analyzed as a separate project. If no directories are passed in the command line, all of the subdirectories of the current directory will be analized.

For example, suppose you want to process 5 consecutive releases of *myproject*, from version 0.1.0 to 0.5.0.

- •

  First you unpack the release tarballs for those versions in a directory, say /tmp/analysis:

  ```
    $ ls -1 /tmp/analysis
    myproject-0.1.0
    myproject-0.2.0
    myproject-0.3.0
    myproject-0.4.0
    myproject-0.5.0
  ```

- •

  Then you change to that directory, and then run **analizo metrics-batch**:

  ```
    $ cd /tmp/analysis
    $ analizo metrics-batch
  ```

- •

  **analizo metrics-batch** will collect the metrics data in a single .csv file, that you can import in spreadsheet software or statistical packages.

analizo metrics-batch is part of the analizo suite.

## OPTIONS

- \--parallel N, -p N

  Activates support for parallel processing, using *N* concurrent worker processes. Usually you will want N to be less than or equal to the number of CPUs in your machine.

  Note that analizo metrics extraction is a CPU-intensive process, so setting N as the exactly number of CPUs you have may bring your machine to an unusable state.

- \--output \<file\>, -o \<file\>

  Write output to \<file\>. Default is to write to *metrics.csv*. That file can then be opened in data analysis programs.

- \--quiet, -q

  Suppresses messages to standard output.
