About pattern matching for data movement policies
Within a policy, you can use a pattern to specify that the rule applies to file names or directory names that match the pattern. By using a pattern, you do not need to know the exact file name in advance; the files that match the pattern are selected dynamically.
A pattern uses special characters, which are case sensitive. There are the following types of patterns:
Directory patterns
A pattern that ends with a slash (/) is matched only against directories.
File patterns
A pattern that does not end with a slash (/) is matched only against files.
The following is a list of supported special characters and their meanings:
* (asterisk) | Matches any character any number of times. |
? (question mark) | Matches any single character. |
** (two asterisks) | Matches across child directories recursively. The pattern fs1/dir1/a.pdf fs1/dir2/b.pdf fs1/dir3/dir4/c.pdf dir5/d.pdf e.pdf then the pattern The pattern The pattern |
[ ] (square brackets) | Matches either range or set of characters. [0-5] will match any character in range of 0 to 5. [a-g] will match any character in range of a to g. [abxyz] will match any one character out of a,b,x,y,z. |
! (exclamation point) | Can be used as the first character in a range to invert the meaning of the match. [!0-5] will match any character which is not in range of 0 to 5. |
\ (backslash) | Can be used as an escape character. Use this to match for one of the above pattern matching characters to avoid the special meaning of the character. |
