Vary simple file Pumper in GoLANG - SIM-297877 - Aug 6, 2021
Needed a file pumper for a project and wanted to keep using GO so i wrote a simple pumper in go.
Code
package main
import (
"fmt"
"log"
"os"
"strconv"
)
var (
FilePath string
SizeToPump int
)
func main() {
FilePath = os.Args[1]
v := os.Args[2]
i, _ := strconv.Atoi(v)
SizeToPump = i
var wantedSize = int64(SizeToPump * 1024 * 1024) //Makes a MB
fmt.Println("PumpItUp")
fi, _ := os.Stat(FilePath)
fmt.Println("Starting Size", fi.Size(), "bytes")
toPump, err := os.OpenFile(FilePath, os.O_RDWR, 0644)
if err != nil {
log.Fatalf("Error Opening File: %s", err)
}
defer toPump.Close()
_, err = toPump.WriteAt([]byte{0}, fi.Size()+wantedSize)
if err != nil {
log.Fatalf("Error Writing to File: %s", err)
}
fi, _ = os.Stat(FilePath)
fmt.Println("Pumped Size", fi.Size() / 1024 /1024, "MB")
