ripgrep

A fast command-line search tool.

• Recursively search the current directory for a regex pattern:

rg {{pattern}}

• Search for pattern including all .gitignored and hidden files:

rg -uu {{pattern}}

• Search for a pattern only in a certain filetype (e.g., html, css, etc.):

rg -t {{filetype}} {{pattern}}

• Search for a pattern only in a subset of directories:

rg {{pattern}} {{set_of_subdirs}}

• Search for a pattern in files matching a glob (e.g., README.*):

rg {{pattern}} -g {{glob}}

• Only list matched files -- useful when piping to other commands:

rg --files-with-matches {{pattern}}
