Can a DOS batch file write a text file?

anyone have any documentation on how if possible to write out a text file using a dos batch file?

for example in the dos batch file i want it to create a text file (doesn't matter where on the drive) that says HELLO

Place the line below in the batch file and it will write the word hello in a text file.

echo hello >Hello.txt

Try the following (in a batch file):

ECHO HELLO > TESTTEXT.TXT

what about error messages... can i write them out?

lets say i have a line

erase myfile.dll

but the dll is in use so it can't be deleted and DOS tells me so.. can I output the error message from DOS into the text file?

Code:

---

erase myifle.dll > mylog.log

---

BTW: ">" will create a new file (if it doesn't exist) or, will overwrite the file (if it does exist).

">>" Will append to an existing file.

this doesn't output the error message.. it just outputs "c:\dir\myfile.dll" to the text file

Try this. I believe its right, but I have never actually used it :

Redirection using only the > or >> symbols does not output error messages to the text file. To get error messages also, use 2> or 2>>.

Examples:
net use X: \\servername\share$ >>out.txt 2>>out-err.txt
net stop servicename >>out.txt 2>>out-err.txt

this does not work

This process worked for me maybe i'm doing it differnetly then you are for trapping the error message. attached is my batch file and below are the steps that I used to validate this

1) I went into VB and created blank project with just a form and called it the default name of Project1.exe, then I ran this project on the c drive of my machine
2) I ran this batch file which tries to delete the project1.exe while it is running

errorlog.txt is the file it created and test.bat is the file that I ran.
