in thread Oneliner replace in-place adds extra spaces at the end of the file

The solution here isn't to switch the order of -l and -0, but to remove -l entirely.

I use the suggested -0777 when I really want slurp mode

    The solution here isn't to switch the order of -l and -o, but to remove -l entirely.

    Yes, that's a good point, in bliako's example the -l isn't needed, e.g. perl -i -0777pe 's/2/4/gs'.

    In general, one might still want to use -0777 and -l together to change $\. A few more TIMTOWTDI examples doing that:

    $ perl -MO=Deparse -0777l11ne ...
BEGIN { $/ = undef; $\ = "\t"; }
...
$ perl -MO=Deparse -l11n0777e ...
BEGIN { $/ = undef; $\ = "\t"; }
...
$ perl -MO=Deparse -ln0777e ...
BEGIN { $/ = undef; $\ = "\n"; }
...

    thanks for this. minor neatpick: in the whole thread I see different renderings for the number Zero, compare 0, 0 and 0 and 0, I guess your -o is actually -0? I will use -0777 from now one because my files are not huge and slurping gives me more flexibility. Indeed -l and s///g*s* were from my wider use-case.

      Yeah, one use was accidentally the letter "o". Fixed.
