Operations with "-" in Linux File Names

For the operation of & quot;-& quot; in the Linux File Name-general Linux technology-Linux programming and kernel information, see the following for details. In Linux, "-" has a special meaning. For example, adding "-" to the end of a command indicates that "-" is followed by an option. However, there are three methods to create a file with the name "-". For example, to create a file "-":

1. cd.>-

2. vi ---

3. echo "">-

You can create a "-a" file in the current directory by using the preceding three methods. Of course, you can create a new file using other methods. It is troublesome to delete "-a". If you enter rm-a, the system will prompt you:

Rm: Invalid option --

Run 'rm -- help' to obtain more information.

You can delete an object in two ways:

1. rm./-

2. rm ---

You don't need to change the name. Basically, you can add "--" before the file name to indicate the escape characters!
