i want to delete the lines with data #1 and only the #1, not all lines that contain #1.

I have tried sed -n '/'1'/p' which deletes all lines that contains the #1. which is not correct.

Somoen please correct the code

thanks

try this
Code:
sed '/1$/d' filename

To be even more exact you want to anchor the #1 where it exists on a line by itself, so you need to add the beginning of a line "^" and end of line "$" anchors to your command.
Code:
sed '/^1$/d' filename

This command will remove any line that ends with a #1, which will remove the lines that contain 1.3981
Code:
sed '/1$/d' filename

using perl:
Code:
perl -pi -e 's/^1$//' filename
