Linux tput命令 详解

# 1. 设置前景色（文本颜色）
tput setaf 0      # 黑色
tput setaf 1      # 红色
tput setaf 2      # 绿色
tput setaf 3      # 黄色
tput setaf 4      # 蓝色
tput setaf 5      # 洋红色
tput setaf 6      # 青色
tput setaf 7      # 白色
tput setaf 8      # 亮黑色（灰色）
tput setaf 9      # 亮红色

# 2. 设置背景色
tput setab 0      # 黑色背景
tput setab 1      # 红色背景
tput setab 2      # 绿色背景
tput setab 3      # 黄色背景
tput setab 4      # 蓝色背景
tput setab 5      # 洋红色背景
tput setab 6      # 青色背景
tput setab 7      # 白色背景

# 3. 重置颜色
tput sgr0         # 重置所有属性（包括颜色）

# 4. 颜色代码变量（在脚本中使用）
RED=$(tput setaf 1)
GREEN=$(tput setaf 2)
YELLOW=$(tput setaf 3)
BLUE=$(tput setaf 4)
MAGENTA=$(tput setaf 5)
CYAN=$(tput setaf 6)
WHITE=$(tput setaf 7)
RESET=$(tput sgr0)

# 使用示例
echo "${RED}这是红色文本${RESET}"
echo "${GREEN}这是绿色文本${RESET}"
echo "${YELLOW}这是黄色文本${RESET}"

# 1. 设置制表符宽度
tput tabs         # 设置制表符为8个空格（默认）
tput hts          # 设置制表位
tput ht           # 跳转到下一个制表位

# 2. 字符属性
tput smacs        # 进入备用字符集模式
tput rmacs        # 退出备用字符集模式
tput enacs        # 启用备用字符集
tput smkx         # 启用键盘传输模式
tput rmkx         # 禁用键盘传输模式

# 3. 文本对齐（某些终端支持）
tput csr 5 15     # 设置滚动区域为5-15行
tput wind         # 获取窗口大小

# 4. 完整格式化示例
echo "正常文本"
tput bold
echo "粗体文本"
tput sgr0         # 重置

tput smul
echo "下划线文本"
tput rmul

tput rev
echo "反显文本"
tput sgr0

# 5. 表格格式化
echo "$(tput smul)列1$(tput rmul)   $(tput smul)列2$(tput rmul)"
echo "数据1     数据2"
echo "$(tput setaf 2)成功$(tput sgr0)   $(tput setaf 1)失败$(tput sgr0)"
