* fix(cat): do not cat directories Fixes #707 * fix(head): do not let head() read directories Also fixes a typo * fix(sort): do not sort directories Also fixes a typo * fix(tail): do not let tail() read directories Also fixes a typo * fix(uniq): do not let uniq() read directories We also had a test which called sort() instead of uniq(), so we never actually tested the missing-file case. This fixes that as well. This also throws an error for using a directory as output. * fix(pipe): fix breakages with piped commands
