Sheryl is a CLI tool for integrating shell scripts.
To date, a variety of shell scripts and tools have been developed, each playing a sophisticated role.
With this Sheryl, you can bundle tools with such specialties to complete complex tasks quickly and easily.
The setup is a single yaml.
go install github.com/gari8/sheryl/cmd/sheryl@latestPlease, Check docs/step.yaml.
The contents are as follows.
Please, Set environment variables with env.
If there are multiple environment variables with the same name, the one described in this yaml takes precedence.
Please, See steps.
This very intuitive shell script allows you to easily execute each step in order from top to bottom.
env:
REQUEST_PATH: https://google.com
steps:
- name: list
cmd: |
ls -A1
- name: show
cmd: |
echo 'cmd: {{ .list.output }}'
- name: ps
cmd: |
ps aux | grep {{ .show.pid }}
- name: curl
retries: 3
interval: 1s
cmd: |
curl -I $REQUEST_PATHYou can also use Go's template syntax only within a cmd entry, as in echo 'cmd: {{ .list.output }}'.
In the above example, step.name = show uses the output information of step.name = list, and step.name = ps uses the pid information of step.name = show.
Executing command is easy.
Simply execute the run subcommand specifying the configuration file using the c, config option as shown below.
sheryl run -c docs/step.yaml -o simpleresult
