Top Forums UNIX for Dummies Questions & Answers Creating File using the CAT Command Post 302386388 by Corona688 on Tuesday 12th of January 2010 10:20:50 AM

cat is not a command for creating files. cat is a method for concatenating files. (see man cat.) It creates files the same way as any command capable of producing any output whatsoever -- shell redirection allows you to put its output into a file.

Code:
# Echo prints to stdout
$ echo asdf
asdf
# Echo prints to new empty file 'newfile'
$ echo asdf > newfile
# printf prints to stdout
$ printf "%02d\n" 9
09
# printf prints to new empty file 'newfile'
$ printf "%02d\n" 9 > newfile
# printf appends to file 'newfile'
$ printf "%02d\n" 9 >> newfile
# etc...

touch on the other hand is a command for creating new files(and updating their timestamps).
