| ARGS="${@}" | |
| clear; | |
| while(true); do | |
| OUTPUT=`$ARGS` | |
| clear | |
| echo -e "${OUTPUT[@]}" | |
| done |
And I added some additional information to the watch function to make it look like it does in native linux -
watch () { ARGS="${@}" 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
}
Additional update on top of @ManuelReschke's version! I've added the eval command to support the usage of | and other more complex commands
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 "$command_to_run" ]; then
echo "Usage: watch [-n <seconds>] <command>"
return 1
fi
clear
while true; do
# Führe den Befehl aus und speichere Ausgabe und Fehler
OUTPUT="$( eval "$command_to_run" 2>&1)"
clear
echo -e "Every ${interval}s: $command_to_run"
echo ""
echo -e "${OUTPUT}"
sleep "$interval"
done
