How can perl language regular expressions match in multiple lines? Please give example
Can use join like
openFILE,$filename
ordie “Can’open’$filename’:$! ” ;
my$lines=join”,<FILE>;
$lines=~s/^/$filename:/gm;
Or use a loop
open(A, “file”);
while(<A>){
if(/aaa/… /bbb/){
print;
}
}
The above script is to print out only the lines between aaa and bbb.
open(A, “file”);
while(<A>){
unless(/aaa/.. /bbb/){
print;
}
}
The above script is printing out lines other than aaa to bbb.
