Top Forums UNIX for Dummies Questions & Answers Creating File using the CAT Command Post 302386390 by zaxxon on Tuesday 12th of January 2010 10:21:39 AM

At first it is very important in *nix environments to have an eye on case sensitvity. It is a difference to use cat Cat or CAT. Only the 1st will work, but that just by the way.

cat is for showing the content of an already existing file. It alone will not create a file - you will have to redirect output with a > sign into a new file. Maybe this is more appropriate:
Code:
# writes text into the file "newfile"; overwrites it's content if it already exists
echo "Content of my new file" > newfile
# writes text into the file "newfile"; appends content if it already exists
echo "Content of my new file" >> newfile
# creates empty file named "newfile"
> newfile
# creates empty file named "newfile"
touch newfile
