Yes, sorry. It's just clever escaping. Like one would ps | grep [s]omething. I began to use this more because in awk, depending on quoting/context, often times you need to escape your escapes since they're really processed twice, and it gets ugly so I tend to avoid \ when possible now.

this is spam [i need this] probably everything [here] too
this is spam [i need this] and probably i need ] everything here too?
mute@thedoctor:~$ sed 's/[^[]*[[]\([^]]*\)]\([[][^]]*]\)*\([^]]*\)$/\1 -- \3/g' input
i need this -- and i need this too
this is spam [here -- too
this is spam [i need this] and probably i need ] everything here too?
mute@thedoctor:~$ sed 's/[^[]*[[]\([^]]*\)]\(\[.*\]\)*/\1 --/' input
i need this -- and i need this too
i need this -- probably everything [here] too
i need this -- and probably i need ] everything here too?
I also didn't think of not needing to match & sub the last part. That's definitely shorter.
One of the senior administrators gave me a shell script to modify and it begins as follows:

Why the double square brackets? (10 Replies)
Hi,
I just came across an interesting shell script syntax like the one below:

COLLECTD-EMAIL(5) collectd COLLECTD-EMAIL(5)NAME
collectd-email - Documentation of collectd's "email plugin"
SYNOPSIS
# See collectd.conf(5)
LoadPlugin email
# ...
<Plugin email>
SocketGroup "collectd"
SocketPerms "0770"
MaxConns 5
</Plugin>
DESCRIPTION
The "email plugin" opens an UNIX-socket over which one can submit email statistics, such as the number of "ham", "spam", "virus", etc.
mails received/handled, spam scores and matched spam checks.
This plugin is intended to be used with the Mail::SpamAssassin::Plugin::Collectd SpamAssassin-plugin which is included in contrib/, but is
of course not limited to that use.
OPERATION
This plugin collects data indirectly by providing a UNIX-socket that external programs can connect to. A simple line based protocol is used
to communicate with the plugin:
o E-Mail type (e.g. "ham", "spam", "virus", ...) and size (bytes):
e:<type>:<size>
If "size" is less than or equal to zero, "size" is ignored.
o Spam score:
s:<value>
o Successful spam checks (e.g. "BAYES_99", "SUBJECT_DRUG_GAP_C", ...):
c:<type1>[,<type2>,...]
Each line is limited to 256 characters (including the newline character). Longer lines will be ignored.
