Useful Regular Expressions
If you are familiar with regular expressions (regex), you can do almost anything without tools. A regular expression is a technology that allows text searches under a variety of conditions.
Incidentally, this tool also uses regular expressions in its programs. For example, “Remove blank lines” is represented by
^\s*?$(\r\n|\r|\n)? is a regular expression. These characters are called meta characters and have an abstract meaning. The regular expression is matched by combining these meta characters.
||Beginning of line|
||0 to n whitespace|
||End of line|
||0 to 1 line feed|
I have also written an article on regular expressions, if you would like to read it.
