Creating file from shell input in Linux

Question

I want to create a file from shell input. That is, I want to run some command, then type the desired contents of my file, then press Ctrl-D and have it create my file with the contents I typed in.

What would be the command for that?

Answer 1

You use the cat command to concatenate STDIN to the file like so: cat >> out.txt (or to blow away the already existing file, don't append cat > out.txt) then type when done press ctl+d to terminate when you are done.
