Go Phrase Finder

This Go script takes in a file path and a search phrase as parameters. It reads the file and writes the parts of the file containing the search phrase (bounded by blank lines) into a new file.

Requirements

• Go programming language installed (version 1.12 or later is recommended).

Building

Windows

To build an executable for Windows, open your command prompt, navigate to the directory of your script and run:

set GOOS=windows GOARCH=amd64 
go build -o script.exe script.go

Linux

To build an executable for Linux, open your terminal, navigate to the directory of your script and run:

GOOS=linux GOARCH=amd64 go build -o script script.go

macOS

To build an executable for macOS, open your terminal, navigate to the directory of your script and run:

GOOS=darwin GOARCH=amd64 go build -o script script.go

Running the script

Replace script with the name of the executable you just built (script.exe for Windows).

Windows

In the command prompt:

script.exe input.txt "my phrase" output.txt

Linux

In the terminal:

./script input.txt "my phrase" output.txt

macOS

In the terminal:

./script input.txt "my phrase" output.txt

Examples

Let's say we have a text file input.txt with the following content:

дата, час, частота
Lorem ipsum dolor sit amet consectetur adipiscing elit montes potenti, mollis pulvinar nostra nullam aenean ante fames placerat, vehicula porttitor accumsan mi maecenas nisi vel habitant.

дата, час, частота
Fringilla sollicitudin per erat dictumst nascetur scelerisque sociosqu nullam ornare placerat volutpat euismod, rhoncus penatibus cras nostra arcu mi convallis vivamus diam commodo sodales

дата, час, частота
Lorem ipsum dolor sit amet consectetur adipiscing elit montes potenti, mollis pulvinar nostra nullam aenean ante fames placerat, vehicula porttitor accumsan mi maecenas nisi vel habitant.

And we want to find all the blocks containing the phrase "vehicula porttitor". We run:

./script input.txt "vehicula porttitor" output.txt

The output.txt file will now contain all the blocks from input.txt that include "vehicula porttitor".
