display all lines

Dear Experts,

can any one tell me how to display all lines except the last line of a file using awk.
take care

try this:

awk '{

if (NR != $) 
{

print $0
}

}' filename

or 

awk 'NR != $  { print $0 }' filename

Try this and do let me know the output.

 sed '$d' file
awk '{if(NR>1)print x;x=$0}' infile

With ed you can modify your original file right away:

!!! Be careful, this command will modify your original file !!!

ed infile <<'EOF'
d
w
q
EOF
