Here is what I see here,
Code:
$ basename `cat bp`
q[3]

$ a="$1"
a=: Command not found.

$ echo $a

Note : I did try setting set a="$1", as well

Thanks.

I did try it, still it has an issue ... ( basename doesnt work in this fashion )
Code:
$ cat bp | basename
basename: missing operand
Try `basename --help' for more information.

Just FYI ( to keep it even simpler )
Code:
$ set var=a[5]
set: No match.

I believe unix thins [] to be as a range, I do not see a way to escape it either.

Thanks.

No it doesn't work here.
Code:
 $ set var="a[5]"
 $ echo $var
echo: No match.

Thanks.
