Remove the s in sed command and try, s is for substitute but here you only delete.
Code:
sed '/^\.abc/d' inputfile 

# General solution..
sed '/^\./d' inputfile

Hi,

You can better use this.
Code:
 sed 's/^\.\(.*\)//g' filename

Regards,
Indu

Welcome to the forum Indu. Why is that better do you think? The ^ renders the g flag without meaning, since a match can only happen once per line. Also just deleting the first character does not delete the line.
