Very Long Lines in BAT File
Daniel J. McKinley
Is there a way to break a very long command line in a bat file?
On UNIX you can use the backslash character like this:
copy very_very_very_very_very_very_long_file_name1 \
very_very_very_very_very_very_long_file_name2
Is there some equivalent way in the DOS world?

The short answer isNo, there is no equivalent". Further, depending on
the version of DOS running, the total length of a command line is
limited either 127 or 250 (Win 95, with /U:250 on SHELL=... line in
CONFIG.SYS file). However, within these limits some accommodation for
long lines can be made through the application of environment variables.
Assuming there is enough space in the environment, a variable or two can
be used to construct the complete line in pieces, something like this
...
set cmd=copy very_very_very_very_very_very_long_file_name1
%cmd% very_very_very_very_very_very_long_file_name2
set cmd=
or
set vlfn1=very_very_very_very_very_very_long_file_name1
set vlfn2=very_very_very_very_very_very_long_file_name2
copy %vlfn1% %vlfn2%
for %%v in (1 2) do set vlfn%%v=
That's about all that can be done.

Why not just renaming the file to a shorter filename...:-<>
