Specifying mode is the best way to ensure filesystem objects are created with the correct permissions. If mode is not specified and the destination filesystem object does exist, the mode of the existing filesystem object will be used. If mode is not specified and the destination filesystem object does not exist, the default umask on the system will be used when setting the mode for the newly created filesystem object. Giving Ansible a number without following either of these rules will end up with a decimal number which will have unexpected results.Īs of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r). Adding a leading zero (for example, 0755) works sometimes, but can fail in loops and some other circumstances. For consistent results, quote octal numbers (for example, '644' or '1777') so Ansible receives a string and can do its own conversion from string into number. You must give Ansible enough information to parse them correctly.

The permissions the resulting filesystem object should have.įor those used to /usr/bin/chmod remember that modes are actually octal numbers.

For a longer filepath, such as c:\\temp\example, you would specify c:\\\\temp\\example in your regular expression in the search string. You must escape both backslash characters in a filepath by specifying 4 consecutive backslashes for the root portion of the filepath. The filepath is interpreted as c:\temp, one of the backslashes is removed. Searches that include a regular expression that contains a double backslash, such as in a filepath like c:\\temp, the search interprets the first backslash as a regular expression escape character. The backslash cannot be used to escape the asterisk in search strings. Splunk SPL uses the asterisk ( * ) as a wildcard character. If you want to match a period character, you must escape the period character by specifying \.

The period character is used in a regular expression to match any character, except a line break character. The backslash character ( \ ) is used in regular expressions to "escape" special characters. This is interpreted by SPL as a search for the text "expression" OR "with pipe". For example, A or B is expressed as A | B.īecause pipe characters are used to separate commands in SPL, you must enclose a regular expression that uses the pipe character in quotation marks.

Here are a few things that you should know about using regular expressions in Splunk searches.Ī pipe character ( | ) is used in regular expressions to specify an OR condition. You can also use regular expressions with evaluation functions such as match and replace. You can use regular expressions with the rex and regex commands. Splunk Search Processing Language (SPL) regular expressions are PCRE (Perl Compatible Regular Expressions).
