matches 13 + at least one of any character (including a space): 1133. If you want to check for white space in middle of string you can use these patterns : '(\w\s)+' : this must match a word with a white space at least. This is the recommended way, as it matches nbsps encoded in UTF-8 and also all whitespace characters matched by \s. Regular Expressions are sets of characters and/or metacharacters that match (or. The shorthand expression for the space separator character class is /]/. In this example, we will search for spaces in the file named example.txt egrep '\s' example. We will use egrep command which is used to run regular expressions on given text or file. We can use single or multiple \s without a problem. If you know your text is valid UTF-8, you can use the POSIX character classes. Regex Space or Whitespace The regular expression is expressed as \s in the regex language. POSIX character class for space separator (recommended)
REGEX WHITESPACE WINDOWS
However, there are two options you can use. The most common forms of whitespace you will use with regular expressions are the space ( ), the tab ( \t ), the new line ( ) and the carriage return ( \r) (useful in Windows environments), and these special characters match each of their respective whitespaces. For example, the regex t+ t+ matches excess whitespace at the. Due to the dependency on the encoding, \s does not match non-breaking spaces. A regular expression is a sequence of characters that specifies a search pattern in text. The most common forms of whitespace you will use with regular expressions are the space ( ), the tab ( t ), the new line ( n) and the carriage return ( r) (useful in Windows environments), and these special characters match each of their respective whitespaces.
In UTF-8, it can be represented by \u00A0 or \xC2\xA0. 1 You need to match whitespace with s+ and remove it using regex-based search and replace.
Note the single space between and wordc which means that wordA wordB wordc will not match, but wordA wordB wordc will.
If you want to search for 'my cats', instead of: myString. This means match wordA followed by 0 or more spaces followed by wordB, but do not match if followed by wordc. While the accepted answer is technically correct, a more practical approach, if possible, is to just strip whitespace out of both the regular expression and the search string. The representation of non-breaking spaces in a text depends on the encoding. Assuming that it is doing what you want it to. In such cases a non-breaking space character is used.
