Help with SED oneliner

[dbadmin]

Hi Gurus,

I have a text file and need to print the lines before a regular expression and then delete them. I have the following sed oneliner which prints the lines after the regular expression. Please help me in modifying the same to achive the above.

cat test.lst | sed -n '/regexp/,$p'

Thank You!

[gray]# after[/gray]
sed -n '/regexp/,$p' test.lst

[gray]# before ( ugly )[/gray]
sed -n '1,/regexp/p' test.lst

[gray]# before ( optimized, as we learned from PHV )[/gray]
sed '/regexp/q' test.lst
