Your error shows you have too many square brackets...
Code:
#!/bin/bash
echo enter name
read name
if [ "$name" == "b" ] || [ "$name" == "c" ]
then
	echo "$name"
else
	echo "none"
fi

Results; on CygWin at the moment hence dos2unix...
Code:
AMIGA:~> cd /tmp
AMIGA:/tmp> dos2unix readname.sh
dos2unix: converting file readname.sh to Unix format ...
AMIGA:/tmp> ./readname.sh
enter name
b
b
AMIGA:/tmp> ./readname.sh
enter name
c
c
AMIGA:/tmp> ./readname.sh
enter name
d
none
AMIGA:/tmp>_

)Since you a re using bash, as an alternative to wisecracker's suggestion you could use double brackets like so (there should be no space between the double brackets):

Code:
if [[ $name == b || $name == c ]] ; then
  echo "$name"
else
  echo none
fi

or

Code:
if [[ $name == [bc] ]] ; then
  echo "$name"
else
  echo none
fi

--
Note the that with double brackets the variables on the left hand side do not need to be quoted

--
Also note that when using single brackets there should be single equation operators = rather than == and it is best to quote the variables on the lefthand side

Hi Scrutinzer...

if [[ $name == [bc] ]]

That is neat and logged down in the old grey matter for future use...

Thanks a lot, I had no idea that that was possible in bash...

Hi Wisecracker. Yes indeed that is one of the nice features of the double bracket compound statement that with == the right hand side becomes a UNIX pattern when left unquoted. If the RHS is quoted then it becomes a string comparison.

This is similar to how it is done in a standard case statement..
