[rhn-users] unary operator expected ??

[Alfred Hovdestad]

Hi:

I don't think ls returns a true value.  You will probably have to check 
for the existence of a specific file name or pipe the output of ls 
through wc to get a numeric value.

numfiles=`ls /home/bc_bigfiles/pub | wc -l`
if [ $numfiles -gt 0 ]; then echo "Files found in server `hostname`"; fi
