# paraexec
paraexec (Parallel exec) is a command-line tool that allows you to run multiple commands in parallel, with organized output display.
## Usage
```
paraexec ( [/] [=...] [...] )+
```
- ``: A string used to separate different commands
- `/`: (Optional) A custom label for the command output (defaults to ``)
- `=`: (Optional) Environment variables for the command
- ``: The command to execute
- ``: (Optional) Arguments for the command
## Examples
1. Run two simple commands in parallel:
```
$ paraexec :: echo Hello :: echo World
echo | Hello
echo | World
echo = exit status: 0
echo = exit status: 0
```
2. Run commands with custom labels and environment variables:
```
$ paraexec ,, frontend/ NODE_ENV=production npm run build ,, backend/ cargo build --release
frontend | asset main.js 142 bytes [compared for emit] [minimized] (name: main)
backend | Compiling backend v0.1.0 (/app/backend)
frontend | webpack 5.1.0 compiled successfully in 198 ms
frontend = exit status: 0
backend | Finished `release` profile [optimized] target(s) in 10.55s
backend = exit status: 0
```
3. stdout/stderr and exit statuses:
```
$ paraexec :: sh -c 'echo stdout ; echo stderr >&2' :: false
false = exit status: 1
sh | stdout
sh !| stderr
sh = exit status: 0
$ echo $?
1
```
## Installation
```
$ cargo build --release
$ cp target/release/paraexec /path/to/bin/
```
