Grouping Files into FilesetsGrouping Files by Filename13-4 CLI Storage-Management Guide• ? is any single character, or no character.• [...] matches any one of the enclosed characters. For example, [xyz]matches x, y, or z.• [a-z] matches any character in the sorted range, a through z.• [^...] or [!...] matches any character that is not enclosed. For example,[!xyz] matches any character except x, y, or z.ignore-case (optional) matches the above without considering letter case.For example, the following command set matches files in any directory named “xml”or “xsl” (upper or lower-case), such as “/www/xml,” “/www/XSL,” “/var/log/Xml,”“/xsl,” or “/XML:”bstnA6k(gbl)# policy-filename-fileset inXmlOrXslDirsbstnA6k(gbl-ns-vol-fs-name[inXmlOrXslDirs])# path match “*/x[ms]l” ignore-casebstnA6k(gbl-ns-vol-fs-name[inXmlOrXslDirs])# ...Using a Complex Regular ExpressionYou can also match directories using a more complex regular expression. For thisoption, use the regexp keyword along with a quoted regular expression:path regexp “regular-expression” [ignore-case]whereregular-expression (1-1024 characters) uses IBM’s ICU conventions forregular expressions (such as “.*\.htm*”, or “[a-z]*\.txt”). The quotes arerequired. The section below provides details for the regular-expressionsyntax.ignore-case (optional) matches the above without considering letter case.A regular expression makes it possible to be very specific about your matchingcriteria.The * and ? match any character, including the “/” character. (The “/” is the Unixdelimiter between directories.) Therefore, path match /usr/*/bin matches both“/usr/local/bin” and “/usr/src/mydir/tmp/bin.” This may be unexpected for Unix users.
