# Test commands for null byte behavior across shells
# Lines starting with # are comments and will be ignored
# Empty lines are also ignored

# Basic printf tests - these should work identically
printf "hello"
printf "before\\x00after" 
printf "before\\000after"
printf "test\\x00"
printf "\\x00test"
printf "a\\x00b\\x00c"

# Printf with format specifiers
printf "%s\\n" "test"

# Echo tests - different shells may behave differently
echo "before\\x00after"
echo -e "before\\x00after"

# Dollar quote expansion - should stop at null bytes
echo $'before\\x00after'
echo $'test\\x00'
echo $'\\x00after'

# Variable assignments and expansions
a=$'test\\x00after'; echo "$a"

# More complex printf cases
