errno [−s] [−−search] {word} |

errno [−S] [−−search−all−locales] {word} |
errno looks up errno macro names, errno codes, and the corresponding descriptions. For example, if given ENOENT on a Linux system, it prints out the code 2 and the description "No such file or directory". If given the code 2, it prints ENOENT and the same description.
−l, −−list
List all errno values.
−s, −−search
Search for errors whose description contains all the given words (case−insensitive).
−S, −−search−all−locales
Like −−search, but searches all installed locales.
