Very Computer

I'm new to Unix scripting and am struggling with what seems to be very
simple, could someone please help stop my madness.

set -x
for ftpserver in isg1uw aixprod
do
    case "$ftpserver" in
        aixprod)
            ...
            ;;
        isg1uw)
            ...
            ;;
    esac
    if "$ftpserver"=aixprod
    then
        print "print anything"
    fi
done

The case statement is evaluated and executed properly, but the if statement
always evaluates $ftpserver=aixprod to be true and continues to print "print
anything".  When I use set -x, I can see the following output

isg1uw=aixprod
bckupstat.sh[49]: isg1uw=aixprod:  not found.
+ aixprod=aixprod
bckupstat.sh[49]: aixprod=aixprod:  not found.

All help would be greatly appreciated

Thank you
Jordan

Any ideas?

Nicholas already answered you on this, as it seems it is simply your
shell syntax that is causing a problem. Nick uses the double brackets
[[ like_this ]] around the test portion of your if statement. Many
people also right it as follows:

if test "${ftpserver}" = "aixprod"
then
   print "print anything"
fi

The "test" command is listed in the AIX Command Reference to show you
all the nice little flags you can use, and it tends to be a bit easier
to read than using brackets all over the place. Of course, everyone
has their own preferences and there are probably 4-5 ways to
accomplish the same thing.

For example, imagine the following if statement:

   if [[ "`oslevel | cut -f1 -d'.'`" = "4" ]]

Then rewrite it this way and it still works the same:

   if test "$(oslevel | cut -f1 -d'.')" = "4"

Jordan

if test "${ftpserver}"="aixprod"
then
    print "print anything"
fi

The set -x output returns
...
test isg1uw=aixprod
print
...
test aixprod=aixprod
print
...

The if statement always evaluates to true, am I missing something?

Thanks again,

Jordan
