I think you can use like Code:
sed 's/.*line//g' file1 or sed -e 's/firstline//g' -e 's/secondline//g' file1 |

i forgot to mention, the input file can be
sssssssssss firstline secondline pppppppppp ssssssssss or sssssssssss firstline secondline pppppppppp ssssssssss ie firtsline secondline can be on the same line or on different lines, and we should only delete only if we can find both firstline and secondline continueously. otherwise it should be retained |

Acccording to my requirement it should not delete third 'firstline' because there is no 'secondline' string after that. it should delete only if 'firstline secondline' comes contionusly. It can have \n in between.
bash-3.00$cat file1 hello ssssssssss firstline secondline pppppppppp ssssssssss sssssssssss firstline secondline pppppppppp ssssssssss firstline ssssssssssss bash-3.00$ sed -e 's/firstline//g' -e 's/secondline//g' file1 ssssssssss pppppppppp ssssssssss sssssssssss pppppppppp ssssssssss ssssssssssss bash-3.00$ |
