When reading the content of a script, I found something like:

echo "An Example" > !$

So I wonder what does !$ mean in bash .

Well i found that !$ means last argument so for an example :

touch /tmp/file1

Here the argument is /tmp/file1 , so !$ replaced /tmp/file1 in echo example .

If then you type the command du -b !$ , the output will be the disk usage in bytes for /tmp/file1
