Sorry if it's in the FAQ, but which is better for the first line
of a script?:

#!/bin/sh -

or

#!/bin/sh

I thought I read somewhere that "#!/bin/sh -" was more
secure; if so why?

thanks in advance,

#!/bin/sh - (or #!/bin/sh -- on some implementations of UNIX) will stop
unwanted options being passed to the interpreter. This can help to make
setuid scripts more secure. See FAQ.
