unix - Create text file and fill it using bash

Question

I need to create a text file (unless it already exists) and write a new line to the file all using bash.

I'm sure it's simple, but could anyone explain this to me?

Answer 1

Creating a text file in unix can be done through a text editor (vim, emacs, gedit, etc). But what you want might be something like this

echo "insert text here" > myfile.txt

That will put the text 'insert text here' into a file myfile.txt. To verify that this worked use the command 'cat'.

cat myfile.txt

If you want to append to a file use this

echo "append this text" >> myfile.txt
