The document discusses using grep to analyze source code. It describes searching a codebase to map the flow from an HTTP request to database tables. Regular expressions and commands like find, grep, cut, and sort are used to recursively parse methods and classes. The writer believes grep can solve any search problem if the rules are understood and offers to demonstrate the code analysis.

grep = 手足の様に使える
find =もはやgrepのオプションだよね？
while = もはや(ry
cut/sed/tr/sed/uniq/awk = (ry

② ImportにTARGETになるClassが含まれているか
grep
③ 読んでいるmethodを上からgrep
④ 読んでいたらネストしてやっぱり2-3を繰り返す

grepを使いこなすとServer

かいう謎行動が激減するので
使ってみてね！
