| Subject: Problem with sed
| 
| I rarely use sed, so I admit to not being fully acquainted with its
| idiosyncrasies,; however, this one is really annoying.
| 
| I am using this command in an attempt to remove empty lines:
| 
| $ sed -i /^$/d /var/tmp/myfile.txt

you have to quote the expression to prevent the '^' and '$' characters from being interpreted by the shell,
for example 

sed -i '/^$/d' /var/tmp/myfile.txt
