How can I write new line - Echo command

Question

I have a log file and simple bash script:

echo -e "$date $totalsize $dupsize $per" > log.txt

But when I execute this script, it write first line of log.txt and show me just last data.

I tried \n but does not working.

How can I write to new line when I execute this script?

I assume what you mean is that you want to append to the log.txt? In that case, use:

echo -e "$date $totalsize $dupsize $per" >> log.txt

Note the >> which means append.

Using > will create a new file (overwrite it) each time it's run, containing whatever you echo to it.
