DOS学习入门 & 精彩文章（教学室） » Puzzles about the echo command writing to files

In DOS, you can use the echo test>a.txt to create a text file named a.txt with the content test. I want to ask, when using the echo command to write echo <%script %> >a.txt, it cannot be written to the file. What methods are there to solve this? Also, in DOS, is there any way to modify a certain line of a file, just like vi? Thank you everyone.

echo ^<%script%^> >a.txt This way you can successfully write the text

Echo hello world>filename can write the string 'hello world' into the file. Then you can run type filename, and you can see hello world displayed. Of course, you can also use the command echo nul>filename to clear the file without deleting it. Note: it's nul, not null @_@
