Glob Filtering#
Some nodes provide an input to filter files or directories using glob patterns like in Dir Walk or Storage Walk.
If the syntax of the pattern is not correct, the node will fail through its Error output.
Pattern Syntax#
*- Matches any sequence of non-separator characters?- Matches any single non-separator character[ ]- Matches any character within the brackets[^ ]- Negates the character class-- Specifies a range of characters\- Escapes the next character
Examples#
| Pattern | Description | Matches | Does Not Match |
|---|---|---|---|
* |
Match all files in a directory | file.txt, document.pdf, image.png |
- |
*.txt |
Match specific file extensions | notes.txt, readme.txt |
document.pdf, image.png |
file?.txt |
Single character wildcard | file1.txt, fileA.txt |
file12.txt, fileABC.txt |
*/data/*.csv |
Files in nested directories | project/data/file.csv, archive/data/record.csv |
project/file.csv |
*.log;*.txt |
Combine multiple patterns | server.log, data.txt |
image.png, notes.docx |
file[0-9].txt |
Character ranges | file1.txt, file2.txt, ..., file9.txt |
file10.txt, fileA.txt |
file[^a-z].txt |
Negate character class | file1.txt, file9.txt |
filea.txt, fileb.txt |
file\\?.txt |
Escaping special characters | file?.txt |
fileA.txt, file1.txt |
Combining Patterns with Delimiter#
When using multiple glob patterns, separate them with the ; delimiter. If any of the patterns match, the file or directory will be included in the results.
Example#
- Pattern:
*.log;*.md - Matches:
server.log,README.md - Does Not Match:
notes.txt,image.png
