Javascript format date time

var today = new Date();
var dd = today.getDate();

var mm = today.getMonth()+1;
var yyyy = today.getFullYear();
var hh = today.getHours();
var ii = today.getMinutes();
var ss = today.getSeconds();

if(dd<10)
{
dd='0'+dd;
}

if(mm<10)
{
mm='0'+mm;
}
today = yyyy+'-'+mm+'-'+dd+' '+hh+':'+ii+':'+ss;

console.log(today);
today = mm+'/'+dd+'/'+yyyy;
console.log(today);
today = dd+'-'+mm+'-'+yyyy;
console.log(today);
today = dd+'/'+mm+'/'+yyyy;
console.log(today);

Shell script input trick

In the occasion where you are not sure how long the user input might be and you want to capture it all, you would use $@ instead. In the following example, I took in the entire string and print it out word by word after breaking them into a string array according to the spaces in between.

In script run_this.sh:

userInputs=($@)
for i in "${userInputs[@]}";; do
echo "$i"
done

Running the command:

./run_this.sh who knows how long this can go
who
knows
how
long
this
can
go

Running command at start up with crontab

    Running crontab -e will allow you to edit your cron.

    Adding a line like this to it:

    @reboot /path/to/script

    will execute that script once your computer boots up.
