For someone who apparently has no idea what he's talking about, you sure say a lot.

No, you missed it. You need the quotes *everywhere* that a variable is referenced.
In script2.sh, $1 only contains the string "this". There is no safe way to pass $1 (containing string "this parameter") from script1 to script2 as a single, trustable parameter.
file: script1.sh #! /bin/bash script2.sh "$1" # Doesn't help to quote in script2 if not quoted in script1 exit 0;
file: script2.sh #! /bin/bash echo "$1";
Here are the offending lines:
for file in $* do mv ${file} $prefix$file done
for file in "$@" do mv -- "${file}" "$prefix$file" done
No amount of quoting will make TLDP's "move a bunch of files" script actually work reliably.
That was a bad URL to have pointed you to, because that's a horrible example of shell programming. I hope "felix hudson" has gotten a bit smarter since then. However, just because felix wrote a bad script does not make "bash is incapable ..." true, any more than you chanting it repeatedly does.
