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 ?

NAME
podofopages - move and delete pages in a PDF document SYNOPSIS
podofopages [--delete] [--move] [inputfile] [outputfile] DESCRIPTION
podofopages is one of the command line tools from the PoDoFo library that provide several useful operations to work with PDF files. It can move and delete pages in a PDF document. OPTIONS
--delete NUMBER Deletes the page NUMBER (number is 0-based). The page will not really be deleted from the PDF. It is only removed from the so called pagestree and therefore becomes hidden. The content of the page can still be retrieved from the document though. --move FROM TO Moves a page FROM TO in the document (FROM and TO are 0-based). SEE ALSO
