How to delete line from a file

Hi ,

I have a file it content is like that

/vol.nas/u08/aip_triage/hany/Tesko/:CC::RPAS
/home/biblawh/myscript:CC::RPAS

i need to search for a certain pattern inside that file and delete the line if i find this pattern without redirecting the output into another file .

so i used the following code but i have problem when the pattern that i am looking for is not in the first line :

DelLine=`awk -F':' '{ if ("'"$DPATH"'" == $1) print NR }' file2.txt`
echo $DelLine
/bin/echo "/$DelLine/d\nwq!" | ex -s file2.txt

any clue how can i do that ?
