check if it's there

Dear,

I want to check if the file in the if code is there, but I don't know how to do it?
if [ ??? ]

Can someone assist me please?

Thanks!

Code:
kopie()
{
    echo " Geef de naam van bestand + plaats vanwaar gekopieerd moet worden en waarnaar : "
    echo -n " Plaats : "
    read plaats
    echo -n " Geef de naam van het te kopiëren bestand : "
    read bestand
    echo -n " Directory naarwaar : "
    read naarwaar
    if [ $plaats/$bestand]
}

You can test for the existence of a file
Code:
if [ -f $plaats/bestand ] ; then   # note the spaces around the brackets
    echo "found it"
else
   echo "cannot find it"
fi

few more
Condition is true if
-f file file is a regular file (not a directory nor other special file)
-e file file exists
-s file file exists and is not empty

Thanks

I've got this now.
I still have 1 problem, in the last if [ -f $naarwaar/$bestand ] it always goes into the else, even if it's true.
If this last issue is fixed then I have my first working script in Ubuntu !!

Someone?


Code:
kopie()
{
    echo -n " Plaats van waar: "
    read plaats
    echo -n " Geef de naam van het te kopiëren bestand : "
    read bestand
    echo -n " Directory naar waar : "
    read naarwaar
    if [ -f $plaats/$bestand ]
    then
        echo "Bestand $bestand bestaat in $plaats"
        if [ -f $naarwaar/$bestand ]
        then
            echo " Bestand bestaat reeds in $naarwaar"
        else
            echo "$naarwaar bestaat niet, of $bestand staat reeds in $naarwaar"
        fi
    else
    echo "Bestand $bestand bestaat niet in $plaats, of de directory $plaats bestaat niet"
    echo -n "Kopiëren niet uitgevoerd"
    fi
}

    read bestand

    read naarwaar
[[ ! -d "$plaats" || ! -d "$naarwaar" ]] && echo "Warning: $plaats or $naarwaar is not a directory"
[[ ! -r "$plaats/$bestand" ]] && echo "cannot read  $plaats/$bestand"
if [ -f "$plaats/$bestand" ]
    then
        echo "Bestand $bestand bestaat in $plaats"
        if [ -f "$naarwaar/$bestand" ]
        then
            echo " Bestand bestaat reeds in $naarwaar"
        else
            echo "$naarwaar bestaat niet, of $bestand staat reeds in $naarwaar"
        fi
    else
    echo "Bestand $bestand bestaat niet in $plaats, of de directory $plaats bestaat niet"
    echo -n "Kopiëren niet uitgevoerd"
    fi
}

OK,
this solves my question.
1 more thing, why do you type that first line? It works fine without it.
plaats="" ; naarwaar="" ; bestand=""

Thanks!
