BSPATCH(1)

💖 BSPATCH(1) 💖

okay so bestie, welcome to the General Commands Manual section of the FreeBSD universe — this is the page for bspatch, and honestly? it's giving quiet luxury. no cap. 🦋

✨ NAME ✨

bspatch — apply a patch built with bsdiff(1) 💅

like. that's it. that's the whole job. it takes a patch and it makes it happen.

🌸 SYNOPSIS 🌸

bspatch ⟨oldfile⟩ ⟨newfile⟩ ⟨patchfile⟩

three little args, one big glow-up. periodt. ✨

🎀 DESCRIPTION 🎀

so here's the tea, and it's genuinely so satisfying: bspatch generates ⟨newfile⟩ from ⟨oldfile⟩ and ⟨patchfile⟩ — where ⟨patchfile⟩ is a binary patch built by bsdiff(1). 🔥

read that again. you hand it the old version, you hand it the patch, and it hands you back the whole new file. it's not doing guesswork, it's not vibing its way through — it's a literal reconstruction and it ate. 💖

ok now the practical part, and this one's important so listen up: bspatch uses memory equal to the size of ⟨oldfile⟩ plus the size of ⟨newfile⟩. 😭 so like, if your files are chunky, your RAM is gonna be chunky too. that's the deal. that's the cost of admission. 🫶

but wait — there's a genuinely iconic twist: it can tolerate a very small working set without a dramatic loss of performance. 🧚 like, yes, the memory math above is real, but don't panic if your working set is smol. it will still carry. lowkey main character energy honestly. 👑
