In Unix, how do I delete a file with a tilde in the username?

In UNIX and GNU/Linux the '~' means something special when running a command. The '~' character refers to your own home directory in the Unix Operating System. For this reason Unix file names usually do not start with a '~'. One time when something like this may be seen is if a file was moved to the system from a different operating system that does not have the same restrictions on file names. These files can be removed by escaping the file name using the '\' character. For example if we wanted to remove a file called -foo we could enter the Unix command:

rm \~foo

In UNIX and GNU/Linux the '-' means something special when running a command. The '-' character tells the Unix Operating System that the next character is what is called a option, which tells the operating system how a command is going to be run. For this reason Unix file names usually do not start with a '-'. One time when something like this may be seen is if a file was moved to the system from a different operating system that does not have the same restrictions on file names. These files can be removed by escaping the file name using the './' character. For example if we wanted to remove a file called -foo we could enter the Unix command:

T101979-05.tar.gz: gzip compressed data
eden: ~> file dangerous-fork-patch
dangerous-fork-patch: executable /sbin/sh script

You can also get a clue from the extension (although UNIX doesn't generally enforce any kind of file naming convention). Here are some common ones:
