CG_MERGE(1)

💅 CG_MERGE 💅

okay so real talk, this is the cg_merge page from section 1 of the manual — the one and only. she's a little vintage, she's a little deprecated, but she still shows up and does her thing 🎀

---

✨ NAME ✨

cg_merge — the deprecated girlie who merges multiple Cachegrind output files into one 🦋

---

✨ SYNOPSIS ✨

cg_merge [options] [cachegrind-out-files...]

---

✨ DESCRIPTION ✨

so basically cg_merge sums together multiple Cachegrind output files and mushes them into a single Cachegrind output file. math but make it cache stats, yk? 💖

now for the part nobody loves: she is deprecated. not because she did anything wrong, but because cg_annotate can now do much the same thing — but better. yeah. better. it's giving "we love growth" but also 🫶 rip to a real one.

---

✨ OPTIONS ✨

• -o outfile — writes the output to outfile instead of to standard output. lowkey the only option and honestly she ate 💅

---

✨ SEE ALSO ✨

• cg_annotate(1)
• valgrind(1)
• $INSTALL/share/doc/valgrind/html/index.html
• http://www.valgrind.org/docs/manual/index.html

go read those, bestie, iykyk 🌸
