Linux is an amazing OS because you can do a lot inside it. Here is a bunch of Tips & Tricks I have found. Find the current time in the timezone you want: $ TZ='America/Los_Angeles' date Tue Dec 11 04:07:18 PST 2018 $ TZ='Europe/London' date Tue Dec 11 12:08:49 GMT 2018 Note: All available timezones can be found at /usr/share/zoneinfo. I recommend to view it using timedatectl list-timezones command. $ timedatectl list-timezones | grep Europe Generate random password string using date and md5sum or sha256sum $ date | sha256sum | base64 | head -c 8 ; echo Y2RhODhh $ date | md5sum | base64 | head -c 8 ; echo YWNjYzU4 Generate pseudo-random string using OpenSSL $ openssl rand -hex 8 d0388693bd744e0e $ openssl rand -base64 32 | head -c 12 ; echo uvics5KjODkt Generate random password string using gpg utility $ gpg --gen-random --armor 1 12
