Regular Expression Directory Name Examples

The following are several examples of regular expression directory name usage:

• Windows:

  c:\\eGate$\\^client\\collab\D\\ ...

  The expression \D indicates any non-digit character.

  d:\\a.b\\c.d\\e.f\\g.h\\[0-9]\\ ...

  The symbol “.” means any character

• Windows UNC notation:

  \\\\My_Machine\\public\\xyz$\\^abc

  The prefix for Windows UNC notation is \\. After escaping, it becomes \\\\.

• UNIX:

  /abc\d/def/ghi/ ...

  The expression \d means any digit character.

  /^PRE[0-9]{5}\.dat$/ ...

  This expression means to begin with PRE followed by a five-digit number and use a .dat extension. The symbol \. means to interpret the real character (a period) instead of any character. Therefore, PRE12345.dat does match, but PRE123456dat does not.
