An alternative to grep which uses JavaScript's Regex, supports a match and a match-and-replace

## Installation

```

npm i jsgrep-cli -g

```

## Example

Match input from stdin, return any matching line:

```

ls -al ~ | jsgrep " \.[a-z]+rc$"

```

Match and replace lines from stdin. Capturing groups are exposed as `$1`, `$2`... variables (1-indexed), and must probably be escaped to prevent being interpreted by your shell:

```

ls -al ~ | jsgrep ".+ (\.[a-z]+rc$)" "\$1"

```

Passing flags (default `i`):

```

ls -al ~ | jsgrep " \.[a-z]+rc$" --flags iu

```
