Help prioritize the shell practice track.

What you practice.

BashDrill should make common shell shapes recognizable before they touch files, services, or production data.

Syntax

Quoting, substitution, variables, tests, arrays, loops, and the details that break scripts.

Streams

stdin, stdout, stderr, pipes, tee, append, overwrite, and file descriptor habits.

Safety

set flags, traps, dry-run thinking, cleanup, and common automation mistakes.

Sample drill

Capture stdout and stderr.

command 2>&1 | tee output.log

Streams are part of the command shape. BashDrill practices where output goes before a script hides the useful signal.

Why it matters

Small shell details cause large failures.

Practice makes the difference between copying a line that works once and understanding the state it changes.
