To terminate a running Golang process programmatically using the os package, you can use the os.Exit() function. Here's an example:
package main
import (
"fmt"
"os"
"os/signal"
"syscall"
)
func main() {
// Create a channel to listen for termination signals
sigChan := make(chan os.Signal, 1)
signal.Notify(sigChan, os.Interrupt, syscall.SIGTERM)
// Start a goroutine to wait for the termination signal
go func() {
sig := <-sigChan
fmt.Printf("Received termination signal: %v\n", sig)
// Terminate the process
os.Exit(0)
}()
// Simulate a long-running process
for {
// Do some work here...
}
}
In this example, we create a channel (sigChan) to listen for termination signals (os.Interrupt and syscall.SIGTERM). We use the signal.Notify() function to register the channel to receive these signals.
Next, we start a goroutine that waits for the termination signal. When a signal is received, the goroutine will print a message and call os.Exit(0) to terminate the process with an exit code of 0.
The main goroutine then enters an infinite loop to simulate a long-running process.
