easily use the expansion"*":
This what is called filename expansion which use some special characters called wildcards.
suppose you have a directory containing the files (file, file0, file1, file01)
Some know wildcards:
The question mark (?) is a special character that causes the shell to generate filenames. It matches any single character in the name of an existing file.
The shell expands the "file?" argument and generates a list of files in the working directory that have names composed of "file" followed by any single character.
Then the output would be file0 and file1
The asterisk (*) performs a function similar to that of the question mark but matches any number of characters, including zero characters, in a filename.
now the output of the command:
would be file, file0, file1 and also file01
The [ ] Special Characters causes the shell to match filenames containing the individual characters within the brackets.
for example the output of the command:
file0 file1 file01
