shell

Executes a system command and hooks its stdin and stdout into the pipeline.

shell cmd:string

Description​

The shell operator executes the provided command by spawning a new process. The input of the operator is forwarded to the child's standard input. Similarly, the child's standard output is forwarded to the output of the operator.

cmd: string​

The command to execute and hook into the pipeline processing. It is interpreted by /bin/sh -c.

Lots of escaping?

Try using raw string literals: r#"echo "i can use quotes""#.

shell "journalctl -u tenzir-node -f"
