File existence error
I'm trying to verify the existence of a file.

PHP Code:
cd /usr/local/bin
old_boing=`grep -l $old_inst *`

new_boing=boing-$new_ver
print "NEW BOING $new_boing"
print "OLD BOING $old_boing"

if [[ -e $new_boing ]];then
        print "There was no boing"
else
        print "boing exist"
fi 
I know there is no file in the directory, but it keeps telling me that the file exist.
What I'm doing wrong?

Thanks

What is $old_inst?

What is that grep supposed to be doing? It finds files containing whatever $old_inst is, not files named it.

What does it print, exactly, when you run it?

I don't know, and without reading too much into this weird boingy stuff, -e is true if the file exists, so why do you have:

Code:
if [[ -e $new_boing ]];then
        print "There was no boing"

Ahhhh, you are right. I put the prints backward
Its should be

PHP Code:
if [[ -e $new_boing ]];then
        print "boing exist"
else
        print "There was no boing"
fi
