Connecting Masks with Matching Files

To connect each mask with all the matching files, we need to understand the concept of file masks. In computing, a file mask is a string that represents a pattern used to match filenames. It typically includes wildcard characters that can match multiple characters or no characters at all.

Let's break down the given masks and files:

- Mask 1: *list* - This mask includes the wildcard character `*` at the beginning and end, which means it can match any characters before and after the word "list." - Files that match this mask could include "summerreadinglist.txt" and "osennie_listya.jpeg."

- Mask 2: summerreadinglist.txt*.??? - This mask starts with "summerreadinglist.txt" and includes the wildcard character `*` after it, which means it can match any characters after "summerreadinglist.txt." - It also includes the wildcard character `?` three times, which means it can match any single character. - Files that match this mask could include "summerreadinglist.txt123" or "summerreadinglist.txtabc."

- Mask 3: liszt_ferenz.mp3???????.* - This mask starts with "liszt_ferenz.mp3" and includes the wildcard character `*` after it, which means it can match any characters after "liszt_ferenz.mp3." - It also includes the wildcard character `?` multiple times, which means it can match any single character. - Files that match this mask could include "liszt_ferenz.mp3123456789" or "liszt_ferenz.mp3abcde."

- Mask 4: revizor.fb2*_* - This mask starts with "revizor.fb2" and includes the wildcard character `*` after it, which means it can match any characters after "revizor.fb2." - It also includes the wildcard character `_` once, which means it can match any single character. - Files that match this mask could include "revizor.fb2_1" or "revizor.fb2_2."

- Mask 5: osennie_listya.jpeg - This mask matches the exact filename "osennie_listya.jpeg."

Now, let's connect each mask with the matching files:

- Mask 1: *list* - Matching files: "summerreadinglist.txt" and "osennie_listya.jpeg."

- Mask 2: summerreadinglist.txt*.??? - Matching files: "summerreadinglist.txt123" and "summerreadinglist.txtabc."

- Mask 3: liszt_ferenz.mp3???????.* - Matching files: "liszt_ferenz.mp3123456789" and "liszt_ferenz.mp3abcde."

- Mask 4: revizor.fb2*_* - Matching files: "revizor.fb2_1" and "revizor.fb2_2."

- Mask 5: osennie_listya.jpeg - Matching file: "osennie_listya.jpeg."

Please note that the matching files provided above are hypothetical examples based on the given masks. The actual matching files may vary depending on the files present in the system.
