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) Show Sample Output
This is sample output - yours may be different.

Synchronize date and time with a server over ssh (BusyBox-friendly)

Useful if localhost is a small machine running BusyBox, which uses a slightly unusual format to set the date. Remotehost can be pretty much any Linux machine, including one running BusyBox. Uses UTC for portability.

date -u `ssh user@remotehost date -u '+%m%d%H%M%Y.%S'`

Join lines and separate with spaces

Read vmargs.txt, which is a text file that could either be DOS-style (\r\n) or UNIX-style (\n) line endings and join the lines with a space separator. Can this be shortened/made more elegant?

This will generate the same output without changing the current directory, and filepath will be relative to the current directory. Note: it will (still) fail if your iTunes library is in a non-standard location.
