This is how it's designed to work, as specified in the [Ruby spec](https://github.com/ruby/spec/blob/master/core/argf/shared/readlines.rb). Unfortunately, this makes it difficult to use the `-i` flag since `ARGF.readlines` will read to the very last file, meaning that all the output will be written to the very last file. ---------------------------------------- Bug #18909: ARGF.readlines reads more than current file https://bugs.ruby-lang.org/issues/18909#change-98353 * Author: JohanJosefsson (Johan Josefsson) * Status: Open * Priority: Normal * ruby -v: ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- The docuentation says that ARGF.readlines: *Reads ARGF's current file in its entirety* , but this is what happens: `$ cat fileA A $ cat fileB B $ ruby -e 'puts ARGF.readlines' fileA fileB A B` i.e. it reads both the current file and the next one (all files?). -- https://bugs.ruby-lang.org/ Unsubscribe:
