Opencode bash tool spawn user commands using /bin/sh what is not bash :-) #3479
Description
Description
The issue seems like is in the following lines
https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/bash.ts#L149-L154
Here - shell: true
**shell **- If true, runs command inside of a shell. Uses '/bin/sh' on Unix, and process.env.ComSpec on Windows. A different shell can be specified as a string.
I'm expecting from bash tools to execute at least bash, or default process.env.SHELL but sh feels pretty outdated for me.
Something like this feels more suitable (or check bash existance and use it if it exists in the PATH)
const defaultShell = process.platform === "win32"
? true // process.env.ComSpec on Windows
: process.env.SHELL ?? true // $SHELL - *default shell for new sessions* if set, otherwise /bun/sh
const proc = spawn(params.command, {
// use the user's login shell (or sensible fallback) rather than the system /bin/sh default
shell: defaultShell,
cwd: Instance.directory,
stdio: ["ignore", "pipe", "pipe"],
detached: process.platform !== "win32",
})OpenCode version
0.15.18
Steps to reproduce
In opencode write following prompt
Run following bash command
pid=$$
echo "$(ps -p "$pid" -o comm=)"
The result is
/bin/sh on linux
