backrun 0.0.9
Run other programs in background
Requires Python: >=3.9

# backrun
Run other (whitelisted) programs/scripts in background (and maybe as another userid) and save stdout/stderr in log. You may need this when you want to start other long-running scripts (like sync databases) from web-UI.

## Install
~~~
# for this user only
pipx install backrun

# for all users
sudo PIPX_HOME=/opt/pipx PIPX_BIN_DIR=/usr/local/bin pipx install backrun

# old fashioned way
pip3 install backrun
~~~~

## Run background tasks

Prepare config file `backrun.toml`, and run backrun. 

When you need to start some background process, do this:
~~~
echo script1 > /var/backrun/task/123
~~~

This will create *task file* to run `script1` with id 123.

Almost immediately backrun will start to execute script and write stdout/stderr to `/var/backrun/tasklog/123.log`.

When script will finish, backrun will delete task file.

## Details
Script will be executed with uid of backrun script.

Backrun reads only first like of taskfile, so you can put everything (any text, YAML, JSON) starting with 2nd line and script can read it.

script will get environment of backrun. backrun will set two new environment variables for script:
`TASKID` - if of task (e.g. "123"), `TASKFILE` - path to task file. If `user` is set, `HOME` variable is redefined too.


## Example files

### config file
Config file name is either passed as first argument to backrun or first existing file in: `./backrun.toml`, `~/backrun.toml`, `/etc/backrun.toml`.

~~~toml
taskdir = "/var/backrun/task"
logdir = "/var/backrun/tasklog"
logfile = '/var/backrun/backrun.log'

[scripts]
    [scripts.script1]
    path="/usr/local/bin/script1.sh"

    [scripts.script2]
    path="/usr/local/bin/script1.sh"
    user="myuser"
~~~

### script file (script1.sh)
~~~bash
#!/bin/bash

log(){
    echo `date "+%Y-%m-%d %H:%M:%S"` $*
}

log started as user `whoami`
sleep 10
>&2 log "error"
log finished
~~~

### systemd service file
