changing file contents using open function.

#1 Post by bin12 »

i was just wondering how can i change the contents of a file using open function, for example if i have this.

open(FILE, "<:utf8", "$file");
while (<FILE>);
#we read the file to find the part we want to change
close FILE;
open(FILE, ">>:utf8", "$file"); #open to print the output
print $foo #print if it doesnt exist
#how can i do the output that changes the file?
close FILE;

or can i just delete that file and write a new file instead? how? need some little assistance, sorry im still learning perl. :?

you might wanna see this even though its a macro, the eval managed to read/edit/copy/append a text file in macro delete. Assuming the oneline eval is a small plugin inside the macro.

Code: Select all

open(FILE,">","$file");
Done.

actually i want to delete/replace the contents of it not exactly the file, sorry if i post it the wrong way.

if i have a txt file containing this
foo bar

i want to change that to
foo foo or bar bar

Why the fuck does everything think I'm a noob? DO YOU SEE AN "UNLINK($FILE)" IN THERE ANYWHERE? BECAUSE I MUST BE BLIND. Jesus, maybe you shouldn't be a programmer.
