$vi my_script
echo "abc" > file
echo "def" > file

The output is as below
===============

def

Now I want the output as below , there are 5 space between the word "abc" and "def" , can advise what can i do ? thx

I want the output as below
==================
$vi file
abc def

Your first output is wrong, using '>' will overwrite. You'd have to use '>>' to append a new line.
To append with spaces on the same line use

Code:

echo -n "   def" >> file

No, this will result in a file which will contain "def". As the previous poster said, each time you use > the file is reinitialized, unless you use >> instead, to append.

Quote the strings adequately.

Code:

echo "abc     def" > myfile

You can as well use cat << EOF to put whole blocks of text

Code:

cat << EOF

EOF > myfile
