How do you write a batch to rename a certain file extension to something else

Jesus you're a retard, I'm not gonna write it for you. I gave you a reference. Use it, kill yourself, idc

Why are you sperging

whats wrong with her I mean other than being turk

find is ugly use a foor loop it's sexier

Just like write it in python, way more commands, extensions, the code is clearer and the skills you'll learn will be useful as fuck if you are creative enough.

if there are special characters in file names or directories you're fucked kiddo

just use Ant Renamer lol

Yes

who is this Damian Semon?

some turkroach trap

I know her irl, she's not a trap.
And yes she's aware of the meme that people think she's a trap

Are you literally renaming jpg files to pngs? You do realize that doesn't convert then to png files right?

I want to fuck her

why bother with writing a batch for a 3 second job?

Install Perl
rename 's/\.jpg$/.png/' *.jpg

is she a friendly person?

>her

>perl
It's not 1996 anymore.

Is that a boy? Because I'd prefer that person to be a boy.

I don't know her that well.

That's terrible
for i in *.jpg; do mv "$i" "${i%jpg}png"; done

rename .jpg .png *

>${1/.jpg/.png}
What if there are spaces in the file name? You have to change your IFS; find is mess free. Also, his variable substitution guarantees only the file extension is changed.

>What if there are spaces in the file name?
That's why it's in quotes.
>You have to change your IFS
I don't. It already works with spaces.
>find is mess free
His find solution recurses in every subdirectory for no reason.
Hopefully no one was dumb enough to test it in their home directory.
>his variable substitution guarantees only the file extension is changed.
So does mine, it uses backward search.
But I did forget to put in the dots. So it would change a file like "foojpg" too.
But that's a trivial fix.

Why would I install perl for something I can do in a small bash function?

That is not the perl rename
AVAILABILITY
The rename command is part of the util-linux package and is available
from kernel.org/pub/linux/utils/util-linux/.

Consider using PowerShell instead of Batch. Batch is obsolete.

>That's why it's in quotes.
Shit. Wtf did I have difficulty with this before.

>But I did forget to put in the dots
Actually, you wouldn't need to add a period. % removes a non-greedy match from the end of the value.

Why is PS so ugly?

you're not supposed to loop over ls or globs like that, it's bad practice.

Also, renaming a file doesn't change the file format. If you take some foo.jpg and rename it as foo.png, you'll have a .jpg file with a .png extension, which is fucking retarded.

>Actually, you wouldn't need to add a period.
?
$ foo="foojpg" echo ${foo%jpg}png
foopng

That's what the dots would avoid.

Ah wait sorry, I'm an idiot. That wont get matched by the wildcard pattern in the first place.

Everything is an object so expect PascalCase and lots of dots. It's not so bad

He might just have a ton of image files with the wrong extensions.

Buggy image crawler, screwed up batch rename, etc.

>foojpg
Lol

you're right when it comes to ls, but otherwise no.

do you even know why it is considered bad practice? or are you just parrotting something you heard from somewhere else?

the syntax itself isn't so bad, the implementation is the real problem. traditional unixy shells interface with files and pass text whereas powershell interfaces with the same buggy API's vbscript and wmic did

PowerShell interfaces with .NET. VBScript interfaced with DCOM. Different APIs.

It in fact looks extremely non-intuitive. Also non-readable although it uses some long ass operators(?). That's just one thing you'd expect.

absolutely nothing
