Hi,


Thanks a ton for your valueable advise to all and in particular to Franklin52 and ghostdog74.


Here is what I did, I will leave
<?php
?>

on the file which should be ok as ?> cannot be removed when it interlaps.




root@server1 [/opt]# awk -v pat="Host: googlesindication.cn" -v before=7 -v after=9 '
FNR==NR && $0 ~ pat {b=NR-before; a=NR+after;next}
FNR!=NR && (FNR<b || FNR>a) {print $0}
' 1.txt 1.txt
<php
phpinfo();
?>
Testing removal
<?php
?>This line line interlaps with other line

There can be more data on this page


root@server1 [/opt]#







===============================================
I feel the following if it can be implement will work best:


root@server [~]# grep -n "Host: " /home/path/public_html/file | awk {'print $1}' > /root/1234567890 && replace ":" " " -- /root/1234567890
root@server [~]# cat /root/1234567890

/home/path/public_html/file 515



x=cat /root/1234567890 | awk {'print $1}'
y=cat /root/1234567890 | awk {'print $2}'

sed -i '$y-7,($y+9)d' $x

can do the trick be we can then replace the ?> on line $y-7 as it will shit up after code removal

replace ?> in line $y-7 with null or probably replace first two characters in line $y-7 with null.
