I have since learned that you are not supposed to escape things within
brackets at all and simply position them so they have relevant meaning,
and that dot does not need to be escaped inside brackets.
Not sure if my mail is still relevant.

Hello Coreutils Team,
When I use the command:
echo "/lib64/ld-linux-x86-64.so.2" | grep -o '[a-zA-Z\/0-9\-\.]*'
The result is that I get a tokenized string where - has been replaced
with \n
/lib64/ld
linux
x86
64.so.2
The expected result is:
/lib64/ld-linux-x86-64.so.2
When the character class is modified so that the - is not next to the
number 9:
echo "/lib64/ld-linux-x86-64.so.2" | grep -o '[a-zA-Z\/0-9\.\-]*'
/lib64/ld-linux-x86-64.so.2
The expected result is obtained.
I am aware - is used to specify a range, but it is escaped, should
this be the proper behaviour?
Thanks,
Tom
