You can use a here document

#!/bin/bash

cat > "ubuntu story" <<\EOF

EOF

Quoting of any part of the word EOF either as \EOF or 'EOF' for example prevents shell expansion of the contents.

I used a bash shebang since that's what you tagged your question, but here documents are supported in all POSIX shells.

Answer 2

In some of my scripts I do something like this:

touch ~/Templates/"untitled_document"


LOG=/var/log/backup.log
echo "* $(date -R) *" >> $LOG

Or:

fname=/etc/fstab
str1="# Entry for /dev/sdb6 :"
echo $str1 >> $fname

Note that one > overwrites or creates new file and >> adds to end of file. I have additional data I add to log file. Also better with Linux to use CamelCase, under_score or justonename rather than spaces. You have to escape spaces in future commands which makes it more complicated.
