A script that recursively searches for the specified text in the files of the specified directory.
findw -w "a word or a phrase to find" [-d ~/some/path]-w used to specify the text to search for
-d (pseudo-optional*) is used to specify the path of the directory which will be recursively searched.
* you can specify the default directory path in the code itself, at the definition of the `dir_to_search` var, which would be overwritten if you were to provide the `-d` flag. This is useful if you are usually searching only in some one directory.
(preview is of the old version of the script)
