SUMMARY

You can add a line to the end of a file, such as your CONFIG.SYS file, without using an editor if you use the COPY command in the following form:
copy filename.ext + con

MORE INFORMATION

Copy echoes FILENAME.EXT as it is copied, then it echoes CON and the cursor to show that it is now copying from the CONsole. For example:
C:\>copy config.sys + con
config.sys
con
_
This causes MS-DOS to echo CONFIG.SYS and CON, with the cursor. Enter the text to be added to the file, then press CTRL+Z and ENTER to end your modification. The following example adds a line to the end of CONFIG.SYS:
C:\>copy config.sys + con
config.sys
con
shell=c:\command.com c:\ /p /e:512
^z

1 File(s) copied
If only one line is to be added and that line doesn't contain any redirection, you can also use the ECHO command as follows:
C:\>echo shell=c:\command.com c:\ /p /e:512 >> config.sys
NOTE: If the last line of the text file does not contain a carriage return, the line being added is appended to the end of the last line.
