Virtualmin

./install.sh: line 20: syntax error near unexpected token then' ./install.sh: line 20: echo Checking for Perl perl=which perl 2>/dev/null if [ “$perl” = “” ]; then’

Here is a cut and paste

echo Checking for Perl
perl=which perl 2>/dev/null
if [ “$perl” = “” ]; then
if [ -x /usr/bin/perl ]; then
perl=/usr/bin/perl
elif [ -x /usr/local/bin/perl ]; then
perl=/usr/local/bin/perl
elif [ -x /opt/csw/bin/perl ]; then
perl=/opt/csw/bin/perl
fi

Using wget it worked without syntax error.

I had downloaded the file from webmin and that was the bugger with the problem.
