grep ack ag

is one of the most commonly used utilities on Linux. ack is a faster replacement of grep written purely in portable Perl 5 and takes advantage of the power of Perl’s regular expressions. ack is optimized for searching version controlled source code.

пакет silversearcher-ag, (ag chemically represents the element silver) is an optimized replacement for ack. It is 3 to 5 times faster than ack and targets source code search. It ignores file patterns from directories created by version control systems. If there are files in your source repo you don’t want to search, just add their patterns to a .agignore file.

Сейчас злит тем, что не хочет искать, игнорируя регистр. По крайней мере, в кириллице. При smart-case, когда должен искать маленькие буквы без учета регистра, большие - только большие, хотя бы вообще ищет, хотя и регистрозависимо. Если поставить ignore-case - просто ничего не находит.

is a line-oriented search tool that recursively searches your current directory for a regex pattern while respecting your gitignore rules and automatically skip hidden files/directories (smart filtering) and binary files. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.

ripgrep is generally faster than both The Silver Searcher and GNU grep. It defaults to recursive directory search and won't search files ignored by your `.gitignore` files. Use ripgrep if you like speed, filtering by default, fewer bugs, and Unicode support.

On the other hand, if you like multiline search, then ripgrep may not quite meet your needs (yet), and it will never support fancy regex features such as backreferences or lookaround

is a tool for indexing and then performing regular expression searches over large bodies of source code. It is a set of command-line programs written in Go.

Теоретически и ripgrep, и сodesearch поддерживаются в projectile.
