seq

名字

seq - 打印序列数值

梗概

seq [OPTION]... LAST seq [OPTION]... FIRST LAST seq [OPTION]... FIRST INCREMENT LAST

简介

以步INCREMENT打印从FIRST到LAST的数字

• -f, --format=FORMAT use printf style floating-point FORMAT
• -s, --separator=STRING 使用STRING来分割数字(default: \n)
• -w, --equal-width equalize width by padding with leading zeroes
• --help 显示帮助并退出
• --version 输出版本信息并退出

如果FIRST 或 INCREMENT缺失，其默认是1。缺失的INCREMENT默认是1即使LAST小于FIRST。The sequence of numbers ends when the sum of the current number and INCREMENT would become greater than LAST. FIRST, INCREMENT, 和 LAST被解释为浮点数。INCREMENT通常是正数如果FIRST小于LAST。如果FIRST大于LAST，INCREMENT通常是负数。FORMAT must be suitable for printing one argument of type 'double'; it defaults to %.PRECF if FIRST, INCREMENT, and LAST are all fixed point decimal numbers with maximum precision PREC, and to %g otherwise.
