Bash Printf格式不正确

Question

在我的bash脚本中，当大多数列对齐时，我正在打印变量并使用printf格式化输出，有些则不行（请注意：体育媒体）。 这是用于打印数据的代码：

for((counter = 0; counter < ${#views[@]}; counter++))
{
  printf "%-40s | %-9s | %-15s" "${users[$counter]}" "${views[$counter]}" "${duration[$counter]}" #"${ids[$counter]}" "${titles[$counter]}"
  printf "\n"
}

这是输出示例：

users                                    | views     | duration

Answer 1

这就是发明制表符的原因：将文本放在同一位置。

$ a="ExtremeTV"
$ b="Sport Mídia"

$ printf '%18s |\n' "$a" "$b"
     ExtremeTV |
  Sport Mídia |

$ printf '%18s \t|\n' "$a" "$b"
     ExtremeTV      |
  Sport Mídia       |
