Lars Wirzenius: errno lookups on the command line

I’ve had a little command line tool called

for many years now.
It’s a short Python script, and lets me look up Unix

names and values
given values or names.

$ errno 2

ENOENT 2 No such file or directory

$ errno EEXIST

EEXIST 17 File exists

$

This is occasionally very useful when reading logs from various programs.
I thought it might be useful for others as well, so I decided to rewrite
it in C so I can offer it to become part of
moreutils.

It is now in the master branch of moreutils.

Today I added a couple of options:

lists all the

values,
and

does a full text (case insensitive) search of all
descriptions. I also added a script that lets you do the search in all
installed locales. (These changes are waiting for Joey to merge them.
Meanwhile, they’re at
gitorious.)

$ errno-all onnistu | sort -u

EDEADLOCK 0 Onnistui

ENOMEM 12 Muistin varaaminen ei onnistu

ENOTSUP 0 Onnistui

EWOULDBLOCK 0 Onnistui

$

(That’s Finnish.)

Hopefully others will find this useful as well.
