#!/usr/bin/env ruby # Finds the latest Passenger crash log directory and prints its path. # This tool is meant to make it easy to analyze local Passenger crash # logs during debugging sessions. Instead of searching for the crash # log directory path in the output and then copy-pasting that to the # terminal, one can simply invoke one shell command: # # less $(./dev/show-latest-crashlog-dir)/backtrace.log # # This will open the latest crash log's backtrace.log in 'less'. def parse_path(path) File.basename(path).split('.')[1].to_i end def main dirs = Dir["/var/tmp/passenger-crash-log.*.*"].sort do |a, b| parse_path(a) <=> parse_path(b) end if dirs.empty? abort "No /var/tmp/passenger-crash-log.* directories found." else puts dirs.last end end main
