Bash alias to output the current Swatch Internet Time
Output the current time in Swatch “Internet Time”, aka .beats. There are 1000 .beats in a day, and @0 is at 00:00 Central European Standard Time. This was briefly a thing in the late 1990s. More details: https://2020.swatch.com/en_ca/internet-time/ The alias is rather quote heavy to protect the subshell, so the bare command is: $ echo '@'$(TZ=GMT-1 date +'(%-S + %-M * 60 + %-H * 3600) / 86.4'|bc)

Display a block of text with AWK
I find this terribly useful for grepping through a file, looking for just a block of text. There's "grep -A # pattern file.txt" to see a specific number of lines following your pattern, but what if you want to see the whole block? Say, the output of "dmidecode" (as root): $ dmidecode | awk '/Battery/,/^$/' Will show me everything following the battery block up to the next block of text. Again, I find this extremely useful when I want to see whole blocks of text based on a pattern, and I don't care to see the rest of the data in output. This could be used against the '/etc/securetty/user' file on Unix to find the block of a specific user. It could be used against VirtualHosts or Directories on Apache to find specific definitions. The scenarios go on for any text formatted in a block fashion. Very handy.

Print lines in a text file with numbers in first column higher or equal than a value
A text file contains thousands of numbers. This command prints lines were the number is greater or equal than a specified value (134000000).

Use lynx to run repeating website actions
This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies). For creating your keystroke file, use: $ lynx -cmd_log yourfile
