Re: Qshell question: an odd character in a quoted string

Yes, the ` or backtick character is used to run a subshell and collect its
output.

eg:

$ echo $FULLNAME
/path/to/some/name

$ basename $FULLNAME
name

$ NAME=`basename $FULLNAME`

$ echo $NAME
name


Since double quotes support shell interpretation, this also occurs inside
double quotes:

$ echo "the basename is `basename $FULLNAME`"

You can escape it using the backslash character:

$ echo "should\`ve used an apostrophe"

Subject: Qshell question: an odd character in a quoted string
Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxx>

Here's an odd one:

I'm loading a STMF by building an "echo" statement, redirected to the
desired STMF, and passing it to QShell.

e.g.,
> echo "Hello\nI like Spam\n" > /foo/bar

So far, so good.

But if I have (because of some unknown person's typo) a "grave accent"
("back-s'quote"; "`") in the quoted string, e.g.,
> echo "Jon didn`t think"

it doesn't work.

Ignoring the fact that it's a typo, and the individual in question
should have spelled "didn't" with an apostrophe, does the "grave accent"

character have a special meaning in QShell?

And is there a way to escape it, in case somebody has a legitimate
reason to use it in the string that's being passed to my program?
