Help with running shell scripts please!

[amityweb]

Please can somoene share a working bunch example of how to get shell scripts to work? I just cant get it to work!!

I have a Macbook 2020 13". Its zsh shell, although then I have tried sh and bash.

I would like to run a Node server, which I call using NPM which I also run in PM2 so its in the background. So for example, this script works fine in my own terminal as my user:
pm2 start 'npm run dev --prefix /path/to/my/app'

But in Bunch I get a "/bin/sh: pm2: command not found"

So I followed the instructions to load the paths to node, npm and pm2 but I still get the same message. In my Bunch files I have tried these:

---
title: My Title
---
#!/bin/sh
source "$HOME/.profile"
$ pm2 start 'npm run dev --prefix /path/to/my/app'

---
title: My Title
---
#!/bin/zsh
source "$HOME/.zshenv"
$ pm2 start 'npm run dev --prefix /path/to/my/app'

---
title: My Title
---
#!/bin/bash
source "$HOME/.profile"
$ pm2 start 'npm run dev --prefix /path/to/my/app'

I also tried adding the dollar in front of the first two:

---
title: My Title
---
$ #!/bin/bash
$ source "$HOME/.profile"
$ pm2 start 'npm run dev --prefix /path/to/my/app'

or just all but not the first:

---
title: My Title
---
#!/bin/bash
$ source "$HOME/.profile"
$ pm2 start 'npm run dev --prefix /path/to/my/app'

I also added #!/bin/bash to the very top above title (the instructions said add it to the top) but I get an error because it looks like it tries to open ----- and the title as an app, so i guess that's wrong.

My .profile and .zshenv files have this:

export PATH=~/.nvm/versions/node/v18.16.1/bin/npm:$PATH
export PATH=~/.nvm/versions/node/v18.16.1/bin/node:$PATH
export PATH=~/.nvm/versions/node/v18.16.1/bin/pm2:$PATH

if I run $ echo $PATH in a Bunch file it does echo the above as the path, but I get the same error, PM2 command not found, every time.

Its the right path to the scripts, they all work when called., e.g. this works fine:
~/.nvm/versions/node/v18.16.1/bin/pm2

Thanks!!!!

You can't have script lines without a $, at best they won't do anything. So if you want to run a sequence of commands, either create a shell script with a hashbang and call it like: $ myscript.sh Or use a [heredoc format](https://bunchapp.co/docs/bunch-files/scripts/shell-scripts/#heredoc): $``` #!/bin/sh ... ``` However, it seems to me that all your problems could be solved by just providing a full path the the pm2 binary. Do you actually need to load an environment for the command to work?

Thanks for the reply.

If I put the full pm2 path it says it can't find node then. I was hoping to not have to put full paths in the scripts. If I can get it working I'll probably have a lot more scripts for my workflows.

I was also hoping to keep just one file for it all and not have multiple files for one workflow. But it's a last resort I guess.

I'll try the heredoc approach. Thanks

Ahhh I got it working! Does not look like I can add paths to pm2, node, npm direct, just could not get it to work. But calling this line loads NVM:

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

This is actually in the .zshrc file and looks like I was calling the wrong zsh file above. I was sourcing .zshenv.

So now I source .zshrc and it loads the above NVM line its working OK!

Thanks
