Pattern matching is one of the shells most powerful features. The Bash shell allows us to match files based on certain patterns. Using the asterisk and sets we can match most files. Using character classes we can also match based upper and lower case as well as types of punctuation.
- [Narrator] One of the reasons that manipulating files…on the command line can be faster…and more efficient than the GUI is pattern matching.…In Bash, pattern matching is called file globbing,…and all commands can use it.…File globs allow us to match patterns.…For instance, if we wanted to list config files,…we could match files ending in .conf by using an asterisk.…So we'd type in…ls /etc/*.conf…An asterisk matches any type of character…and any number of them.…
So file.* would match any word that starts with file,…has a dot in it, and is followed…by any number of characters.…A question mark matches any type of character…but only one of them.…So file?.txt would match filea.txt and file1.txt.…If you want to match two characters,…you're going to have to include two question marks.…We could match a range or a list of characters…with a set using square brackets.…Each set matches exactly one character,…but that one character can be any of the items…in the range or list.…
By placing a hyphen between the start…and ending characters, we can create a range.…
