Strange Files
We come across files and folders name very regularly. In most of the cases file/folder names are related to the content of the file/folder and starts with numbers or letters. Alpha-Numeric file name are pretty common and very widely used, but this is not the case when we have to deal with file/folder name that has special characters in them.
Example of most common file names are:
something.txt
alphanum21.txt
674659.txt
Examples of file names that have special characters:
#121day.txt
some/file#.txt
*File$*.txt
When You create a file with some special character, you will need to escape those special characters in order to create that file.
A non-quoted backslash \ is the escape character. The backslash \ preceding a character tells the shell to interpret that special character literally.
Example:
If you want to create a file named foo!\.txt You have to escape the characters like so:
$ touch foo\!\\.txt
