【问题描述】：

我正在尝试在 makefile 中编译一些文件时打印 {done}。像这样：

Compiling src/execution/ft_cd.c:                                {done}
Compiling src/execution/ft_check_path.c:                        {done}
Compiling src/execution/ft_echo_pwd_env.c:                      {done}
Compiling src/execution/ft_execution.c:                         {done}
Compiling src/execution/ft_exit.c:                              {done}
Compiling src/execution/ft_export.c:                            {done}
Compiling src/execution/ft_init_env.c:                          {done}
Compiling src/execution/ft_linked_lists.c:                      {done}
Compiling src/execution/ft_linked_lists_rest.c:                 {done}
Compiling src/execution/ft_pipes.c:                             {done}
Compiling src/execution/ft_redirection.c:                       {done}
Compiling src/execution/ft_unset.c:                             {done}
Compiling src/execution/ft_utlis.c:                             {done}
Compiling src/lexer/lexer_debug.c:                              {done}
Compiling src/lexer/lexer_get_tokens_op.c:                      {done}
Compiling src/lexer/lexer_get_tokens_word.c:                    {done}
Compiling src/lexer/lexer_get_tokens.c:                         {done}
Compiling src/lexer/lexer.c:                                    {done}
Compiling src/expansion/expansion.c:                            {done}
Compiling src/parse/check_syntax.c:                             {done}
Compiling src/parse/parser_debug.c:                             {done}
Compiling src/parse/parser.c:                                   {done}
Compiling src/readline/readline_debug.c:                        {done}
Compiling src/readline/readline.c:                              {done}
Compiling src/readline/get_next_line.c:                         {done}
Compiling src/main.c:                                           {done}

但是输出是这样的：

Compiling src/execution/ft_cd.c:                                {done}
Compiling src/execution/ft_check_path.c:                                {done}
Compiling src/execution/ft_echo_pwd_env.c:                              {done}
Compiling src/execution/ft_execution.c:                         {done}
Compiling src/execution/ft_exit.c:                              {done}
Compiling src/execution/ft_export.c:                            {done}
Compiling src/execution/ft_init_env.c:                          {done}
Compiling src/execution/ft_linked_lists.c:                              {done}
Compiling src/execution/ft_linked_lists_rest.c:                         {done}
Compiling src/execution/ft_pipes.c:                             {done}
Compiling src/execution/ft_redirection.c:                               {done}
Compiling src/execution/ft_unset.c:                             {done}
Compiling src/execution/ft_utlis.c:                             {done}
Compiling src/lexer/lexer_debug.c:                              {done}
Compiling src/lexer/lexer_get_tokens_op.c:                              {done}
Compiling src/lexer/lexer_get_tokens_word.c:                            {done}
Compiling src/lexer/lexer_get_tokens.c:                         {done}
Compiling src/lexer/lexer.c:                            {done}
Compiling src/expansion/expansion.c:                            {done}
Compiling src/parse/check_syntax.c:                             {done}
Compiling src/parse/parser_debug.c:                             {done}
Compiling src/parse/parser.c:                           {done}
Compiling src/readline/readline_debug.c:                                {done}
Compiling src/readline/readline.c:                              {done}
Compiling src/readline/get_next_line.c:                         {done}
Compiling src/main.c:                           {done}

这是我打印此输出的规则：

$(OBJECTSDIR)/%.o : $(SOURCEDIR)/%.c
    $(HIDE)$(MKDIR) $(dir $@)
    $(HIDE)/bin/echo -n "Compiling $<:"
    @echo "\t\t\t\t$(GREEN){done}$(RESET)"
    $(HIDE)$(CC) $(FLAGS) -I $(HEADERSDIR) -I $(LIBFT_HEADER) -o $@ -c $<

有更好的方法，但您可以在添加选项卡之前在 echo 中使用回车键重置为第 0 列。 @echo -e "\r\t\t\t\t\t{done}"
@RyanHaining 我试过你的解决方案，效果很好，非常感谢。
@DarkSide77 这很粗糙。 {done} 将始终出现在同一个位置，如果它们碰巧在那里，则会覆盖其他字符

【解决方案1】：

假设您使用的是 POSIX shell，例如 bash 或 dash，请使用 printf 内置命令，而不是使用制表符回显：

    @printf "Compiling %-40s$(GREEN){done}$(RESET)" "$<:"
