# ack
# A search tool like grep, optimized for developers.
# See also: `rg`, which is much faster.
# More information: <https://beyondgrep.com/documentation>.
# Search for files containing a string or regular expression in the current directory recursively:
ack "search_pattern"
# Search for a case-insensitive pattern:
ack --ignore-case "search_pattern"
# Search for lines matching a pattern, printing [o]nly the matched text and not the rest of the line:
ack -o "search_pattern"
# Limit search to files of a specific type:
ack --type=ruby "search_pattern"
# Do not search in files of a specific type:
ack --type=noruby "search_pattern"
# Count the total number of matches found:
ack --count --no-filename "search_pattern"
# Print the file names and the number of matches for each file only:
ack --count --files-with-matches "search_pattern"
# List all the values that can be used with `--type`:
ack --help-types
