## 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:
|
||
|
|
|
||
|
|
```console
|
||
|
|
something.txt
|
||
|
|
alphanum21.txt
|
||
|
|
674659.txt
|
||
|
|
```
|
||
|
|
|
||
|
|
Examples of file names that have special characters:
|
||
|
|
|
||
|
|
```console
|
||
|
|
#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:
|
||
|
|
|
||
|
|
```console
|
||
|

|
$ touch foo\!\\.txt
