pexp

Persistently EXPort environment vars, across sessions.

pexp is a lot like export, but it also persists the variable to disk and instantly refreshes it in every other open session.

Useful for system-wide variables that can change often and are annoying to re-export, like keys, RUST_BACKTRACE and so on!

Usage

pexp FOO BAR
echo $FOO   # prints "BAR"
exit
...
echo $FOO   # still prints "BAR"

Hacks, mostly. It creates a ~/.pexprc file to store every export, and automatically sources it again in the background every time it changes it.

Clone this repository, then build the binary (requires Rust)

git clone https://github.com/Tomcc/pexp.git
cargo install --path pexp

then add this:

source "this_repo/pexp_setup.sh"

in your .bashrc or .zshrc.

It may destroy all your data, fail to work outside MacOS, and hijack your usage of SIGUSR2. You've been warned.
