How do I get rid of the verbose error messages? From: Bjorn P. Brox

Many of the messages from the Unix commands are available in different
languages. This is controlled by the LANG environment variable, the
default being En_US meaning English in the US. All the default messages
have a message number associated with them, e.g.:

$ cat no-such-file
cat: 0652-050 Cannot open no-such-file.

If you prefer the terser Unix-looking error message, set your
environment variable LC_MESSAGES to C, and you will get:

$ cat no-such-file
cat: Cannot open no-such-file.

By default LC_MESSAGES is the same as your environment LANG. Setting
LANG does also work, but should be avoided since it changes
app-defaults lookup etc. See locale(): LC_ALL
