alt Hacker NewsI remember my first shell programming I ever did was batch in windows back in the 3.11/95 days.
The first line was always to turn off echo, and I've always wondered why that was a decision for batch script. Or I'm misremembering. 30 years of separation makes it hard to remember the details.
Echo in that case prints command lines before executing them. Its analog is `set -x` rather than `echo`.
