Deleting a line from a file

Hi, I have a file that has entries for different absolute path on separate lines. eg: /opt/new1 /opt/new2 I need to delete an entry from this file for a given path, for which I am using sed. sed -i 's#^/opt/new1.*$##g' file_entries.txt However this is leaving blank line in between, which I don't want. Can someone help me to do this without leaving blank lines in between. Regards, Saket Sinha
