Multi Counter is a simple commandline app to count certain lines in text files. For example, if you have a folder full of logs and are interested in, say, three different types of log statements that you need to count, Multi Counter is for you.
npm install -g multi-counter
Start by multiCounter some/log/dir. It will output something like this:
some/log/dir/1.txt
All Lines: 9
some/log/dir/2.txt
All Lines: 41
some/log/dir/3.txt
All Lines: 57
some/log/dir/4.txt
All Lines: 49
It becomes way more interesting when a config file is provided: multiCounter some/log/dir -c config.json.
The config file is a JSON-formatted config that looks like this:
{
"patterns": [
{
"name": "Number of single line comments",
"pattern": "^\\s*//"
}
],
"depth": 1,
"filePattern": "\\.log$"
}
MultiCounter will output how often every specified pattern occurred. If the filePattern option is specified, only files matching this regular expression will be counted. The depth option specifies how many directory levels will be traversed. It can be overridden by passing the --depth option to multiCounter.
