grep recursively for a specific file type on Linux

Question

Can we search a term (eg. \"onblur\") recursively in some folders only in specific files (html files)?

grep -Rin \"onblur\" *.html

This ret

Answer 1

You might also like ag 'the silver searcher' -

ag --html onblur

it searches by regexp and is recursive in the current directory by default, and has predefined sets of extensions to search - in this case --html maps to .htm, .html, .shtml, .xhtml. Also ignores binary files, prints filenames, line numbers, and colorizes output by default.

Some options -

-Q --literal
          Do not parse PATTERN as a regular expression. Try to match it literally.
-S --smart-case
          Match case-sensitively if there are any uppercase letters in PATTERN, 
          case-insensitively otherwise. Enabled by default.
-t --all-text
          Search all text files. This doesn't include hidden files.
   --hidden
          Search hidden files. This option obeys ignored files.

For the list of supported filetypes run ag --list-file-types.

The only thing it seems to lack is being able to specify a filetype with an extension, in which case you need to fall back on grep with --include.
