What output will echo > produce?

Question

I don\'t have a linux at hand and instead use compileonline.com to check out some code in bash, yet I\'m new to bash. Could somebody give a hand?

for var
do echo         


        

Answer 1

> always overwrites.

Writing a new line would be achieved by using the “append” redirection operator >>.

Answer 2

It overwrites the file each time

$ cat script.sh 
for var in 123 abv xyz
do
    echo $var > fniz
    cat fniz
done
$ ./script.sh 
123
abv
xyz

If you want to append, use >>
