## ntpdate
There are times when you need to keep the date and time of your system to be correct.
Ntpdate in linux helps you do the same

sudo ntpdate -u ntp.ubuntu.org

ntpdate are installed on most distributions, if not install using apt-get.

## Proxy
ssh -C2qTnN -D 8080 username@xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx is the ip which allows ssh access) (can change the port from 8080 to as per requirement)

You are connected to the proxy. To use the proxy, go the one of your browser
and change the proxy settings to use SOCKS protocol and localhost (127.0.0.1) with port 8080.

## php datetime
Validating a date from format yyyy-mm-dd

$date = DateTime::createFromFormat('Y-m-d', $generatedFrom);
if (!($date instanceof DateTime)) {
  throw new ValidationError('Not valid start date');
}

Similarly other formats can be validated.

## Count Code lines
git ls-files -z | xargs -0n1 git blame -w | perl -n -e '/^.*\((.*?)\s*[\d]{4}/; print $1,"\n"' | sort -f | uniq -c | sort -n
