shell_match

`shell_match`

shell_match — compares string text to a pattern.

shell_match (text, pattern)

t if the text matches the pattern, otherwise nil.

This function compares the text to the pattern using shell-style wildcard rules. The available patterns are as follows:

* matches any number of characters, including zero.
[c] matches a single character which is a member of the set contained within the square brackets.
[^c] matches any single character which is not a member of the set contained within the square brackets.
? matches a single character.
{xx,yy} matches either of the simple strings contained within the braces.
\c (a backslash followed by a character) - matches that character.

To get a directory listing of just *.txt files, use:

shell_match(directory("/etc/readme",0,nil),"*.txt");

Gamma> shell_match("hello","?el[a-m]*");
