Non-English file names work only if entered through a DOS character set compatible editor. File names with characters outside this set do not work in batch files. To get a command prompt with Unicode instead of Code page 437 or similar, one can use the cmd /U command. In such a command prompt, a batch file with Unicode filenames will work.
Another important use of the echo command is to toggle echoing of commands on and off in batch files. Traditionally batch files begin with the @echo off statement.

COMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me.In the case of DOS, it is the default user interface as well.

Changes made to the command line environment after SetLocal commands are local to the batch file. EndLocal command restores the previous settings. [17] The Call command allows subroutines within batch file. The Call command in COMMAND.COM only supports calling external batch files. File name parser extensions to the Set command are comparable ...
Recursively list all files and directories in the specified directory and any subdirectories, in wide format, pausing after each screen of output.

Some examples are: The number of lines from a file to load into a database before committing the transaction. The number of messages to dequeue from a queue. The number of requests to send within one payload.
instruct the directory command to also display the ownership of the files. Note the Directory command name is not case sensitive, and can be abbreviated to as few letters as required to remain unique. Windows: DIR/Q/O:S d* dir /q d* /o:s: display ownership of files whose names begin with d (or D), sorted by size, smallest first.
