The tee command is normally used to split the output of a program so that it can be both displayed and saved in a file. The command can be used to capture intermediate output before the data is altered by another command or program. The tee command reads standard input, then writes its content to standard output. It simultaneously copies the ...
The difference is an exact number of quarters of an hour up to 95 (same minutes modulo 15 and seconds) if the file was transported across zones; there is also a one-hour difference within a single zone caused by the transition between standard time and daylight saving time (DST). Some, but not all, file comparison and synchronisation software ...

The command tells only what the file looks like, not what it is (in the case where file looks at the content).

For instance, if a command opening the Documents folder is bound to the F7 key, this hotkey would trigger that action regardless of what application the user is ...

Together, the type and creator indicated what application should be used to open a file, similar to (but richer than) the file extensions in other operating systems.
File associations can be displayed and edited using the assoc command and with the help of the ftype command it is possible to create association between file type and application which will open files of this type. [3] [4] The Windows shell invokes file association actions through COM, drag and drop, command line calls or through Dynamic Data ...
Files may be copied to device files (e.g. copy letter.txt lpt1 sends the file to the printer on lpt1. copy letter.txt con would output to stdout, like the type command. Note that copy page1.txt+page2.txt book.txt will concatenate the files and output them as book.txt. Which is just like the cat command). It can also copy files between different ...
