Execute commands in parallel.
Goparallel is provided as a single binary. You can download it and drop it in your $PATH.
Pass commands list that are executed in parallel to goparallel by the stdin.
Example1) From a file using cat command.
$ cat commands.ltsv
cmd:echo one
cmd:echo two
$ cat commands.ltsv | goparallel
one
two
Example2) Use echo.
$ echo -e "cmd:echo one\ncmd:echo two" | goparallel
one
two
Example3) You can use a argument instead of stdin.
$ goparallel "cmd:echo one
dquote> cmd:echo two"
one
two
The commands list is defined in a LTSV format at default.
Above examples use cmd key that defines command to execute.
You can use prefix key to output with a prefix.
$ echo -e "cmd:echo one\tprefix:[aaa]\ncmd:echo two\tprefix:[bbb]" | goparallel
[aaa] one
[bbb] two
Goparallel supports other formats. use -f option.
YAML format.
$ cat commands.yml
- {cmd: "echo one", prefix: "[aaa]"}
- {cmd: "echo two", prefix: "[bbb]"}
$ cat commands.yml | goparallel -f=yaml
[aaa] one
[bbb] two
JSON format.
$ cat commands.json
[
{"cmd":"echo one", "prefix":"[aaa]"},
{"cmd":"echo two", "prefix":"[bbb]"},
]
$ cat commands.json | goparallel -f=json
[aaa] one
[bbb] two
