Does Ubuntu Server have a Trash?

Solution 1:

No trash in the Server version. The rm command deletes it.

Solution 2:

You do not say how you delete files.
There could be a "trash" if you use some text mode file manager, for example.

But let's assume you use the rm command in the shell:

Normally, rm should just delete files, without using a "trash". But for various reasons, like installing something accidentally, or using an example .bashrc without checking, it could be something else - it's easy to check, so you should: Use command -v to find out what command you're running with the name rm:

$ command -v rm
/usr/bin/rm

That looks good (1). Equally, /bin/rm would be good.

If rm is changed to use trash, it may look like this:

$ command -v rm       
alias rm=trash-put

or

$ command -v rm       
alias rm=gvfs-trash

Normally, this change is only applied when rm is used in an interactive shell.

Also, you may check whether libtrash is installed in some way. It changes how progams work, including rm, on library call level.

(1) Actually, /usr/bin/rm may be safe-rm, from a package of the same name:

$ ls -l /usr/bin/rm
lrwxrwxrwx 1 root root 7 Feb  1  2014 /usr/bin/rm -> safe-rm

Answering a question from a comment:
If winscp is an implementation of scp, then you can not delete files with it; You copy files to another machine, so you get more copies. You could use it to overwrite files, though - but that's not what you talk about.
