Output only characters between [ABC] and [/ABC]

$ cat somefile.txt

asdf[ABC]dafga
asdfasf
yxcvyxv[/ABC]

yv[ABC]sdfb
sdfgadfg
[/ABC]adf
asdf
$ cat somefile.txt | NEEDEDONELINER > output.txt

So the "NEEDEDONELINER" only outputs the characters between a [ABC] and [/ABC].
[ABC] could occur several times, and there could be random characters around it.
I only need the random chars between the [ABC] and [/ABC].
I don't have time to learn Perl :\
Thank you in anticipiation!
