# Custom prompt patterns for silence until prompt feature
# You can add your own shell prompt patterns as regular expressions
# Each pattern should be on a separate line, format: customPatterns=pattern1,pattern2,pattern3
# Examples:
# For PS1='[\u@\h \W] \$ ' use: \[.*@.*\s.*\]\s*[$#>]\s*
# For "[storm@fenrir ~] $" use: \[.*@.*\s.*\]\s*[$#>]\s*
# For custom prompts ending with specific strings, use patterns like: .*your_prompt_ending$
customPatterns=
# Specific prompt strings to match exactly (useful for very specific custom prompts)
# Format: exactMatches=prompt1,prompt2,prompt3
# Examples:
# exactMatches=[storm@fenrir ~] $,[root@fenrir ~] #
exactMatches=
[time]
