Watch command for Git Bash

watch.sh

#!/bin/bash
ARGS="${@}"
clear; 
while(true); do 
  OUTPUT=`$ARGS`
  clear 
  echo -e "${OUTPUT[@]}"
done

you can add it as a function to ~/.bash_aliases

watch () {
  ARGS="${@}"
  clear;
  while(true); do
    clear
    OUTPUT=`$ARGS`
    echo -e "${OUTPUT[@]}"
    sleep 1
  done
}

And I added some additional information to the watch function to make it look like it does in native linux -

watch () {
  ARGS="${@}"
  clear;
  while(true); do
    OUTPUT=`$ARGS`
    clear
    echo -e "Every 1.0s: $ARGS"
    echo ""
    echo -e "${OUTPUT[@]}"
    sleep 1
  done
}

And I added some additional information to the watch function to make it look like it does in native linux -

watch () {
  ARGS="${@}"
  clear;
  while(true); do
    OUTPUT=`$ARGS`
    clear
    echo -e "Every 1.0s: $ARGS"
    echo ""
    echo -e "${OUTPUT[@]}"
    sleep 1
  done
}

this is awesome!!!

I added the -n parameter support. For example watch -n 5 ls -l

watch() {
  local interval=1 # Standardintervall
  local command_to_run=""

  # Einfache Argumenten-Analyse
  if [[ "$1" == "-n" && "$2" =~ ^[0-9]+(\.[0-9]+)?$ ]]; then
    interval="$2"
    shift 2 # Entfernt -n und die Zahl von den Argumenten
  fi

  command_to_run="${@}"

  if [ -z "$command_to_run" ]; then
    echo "Usage: watch [-n <seconds>] <command>"
    return 1
  fi

  clear
  while true; do
    # Führe den Befehl aus und speichere Ausgabe und Fehler
    OUTPUT="$($command_to_run 2>&1)"
    clear
    echo -e "Every ${interval}s: $command_to_run"
    echo ""
    echo -e "${OUTPUT}"
    sleep "$interval"
  done
}
