Question

I have tried a number of websites for help. This is what I have now. I need to get input in a tcsh script from the user and output to a file till the user clicks ctrl-d

Ambiguous output redirect.

Answer 1

Only one redirection is required.

 cat > fileName

will receive data from the stdin and write the data onto the file.
