The copy command also allows you to append files. To do this Appending files
^^^^ you simply list any number of files as options to copy, each
() separated by a plus sign ( + ), then specify a target file to send the
combined files to; for example:
f^\ copy intro.rpt + body.rpt + b:5um.rpt report
This command combines files named intro.rpt, body.rpt, and
/—^ sum.rpt (on drive B), and places them in a file called report on
the default drive. If you leave out the target file, ms-dos combines
the files into the first specified file.
^\ You can also combine several files into one by using wildcards;
I for example:
^^^ I copy *.txt combin.doc
This command takes all files with an extension of .txt and com
bines them into one file named combin.doc.
' \In the following example, each file that matches *.txt is combined
with its corresponding .ref file. The result is a file with the same
filename but with the extension .doc. Thus, filel.txt is combined
( *\ with filel. ref to form filel. doc, xyz. txt with ocyz. ref to form
xyzdoc, and so on:
/—s copy *.txt + *.ref *.doc
The following copy command combines all files matching *.txt
^-v and all files matching *.ref into one file named combindoc:
copy *.txt + *.ref combin.doc
Warning Do not try to append files if one of the source file
names has the same extension as the target. For example, if the
/—s file alltxt already exists, the following command is an error:
copy * . txt al 1.txt
f) ms-dos would not detect the error until it tried to append alltxt.
But at that point, copy might have already destroyed the alltxt
file.
