RENV(1)

💅 RENV — normalize environment variables 🎀

okay so this is renv, from the General Commands Manual section, and honestly bestie, she's a whole vibe ✨

---

🌸 SYNOPSIS 🌸

renv file ... [-q]
renv name="value" [file]

---

🦋 DESCRIPTION 🦋

so basically, renv filters environment variables and spits them out in a format that's suitable for sh(1) — like, she's making your env vars presentable for the shell, periodt 💅

here's the thing though: only lines that define variable names using the characters [_a-zA-Z0-9] — with a value wrapped in double-quotes — actually get emitted. And yeah, values can be totally empty, that's valid, no problem 🫶

A="one"
B="two"
D=""

now this is the cute part: if the first argument is in the format name=value, renv will store an environment for reference in subsequent labels, iykyk. And by default, entries are appended to $SD/local.env 👑

Optional arguments are as follows:

• -q — validate only, do not print lines. like, just checking, no receipts 😌

---

🧚 LITERALS 🧚

okay so this is the important bit, bestie, listen up 🙈

Escape sequences starting with \, or subshells using $(...), are not permitted. nope, not a thing, don't try it 💀

But $$ expands to a single dollar sign — that one slays ✨

---

💖 EXAMPLES 💖

Print environment variables in a normalized format:

$ renv final.env

Save the status code of the last command:

$ renv LAST_EXITSTATUS="$?"

literally iconic, no notes 🌈

🔥 CAVEATS 🔥

ngl, there's some stuff you should know:

Tabs and multiple spaces are converted into a single space. So like, your formatting? gone. collapsed. it's giving minimalist 🫶 There is no provision for embedding literal double-quotes. none. zero. don't come for her 😭 renv must be found in the current working directory, or in the path defined by SD. so like, she has to be findable, bestie 💅

and that's the whole thing, bestie! ✨ this page is from Debian, dated January 17, 2026 — go forth and normalize those env vars, you've got this 👑💜
