fold命令
fold命令用于限制文件列宽，其会从指定的文件里读取内容，将超过限定列宽的列加入增列字符后，输出到标准输出设备。若不指定任何文件名称，或是所给予的文件名为-，则fold命令会从标准输入设备读取数据。
语法
fold [OPTION]... [FILE]...

参数

-b, --bytes: 计算字节数而不是列数。
-s, --spaces: 在空格处跳过。
-w, --width=WIDTH: 使用n列，而不是默认值80。
--help: 显示帮助信息。
--version: 显示版本信息。

示例
使用fold命令进行分隔，每行最多包含默认值80个字符。
fold file.txt
# fold command in Linux wraps each line in an input file to fit a specified width
# and prints it to the standard output. By default, it wraps lines at a maximum wi
# dth of 80 columns but this is configurable. To fold input using the fold command
#  pass a file or standard input to the command.

使用fold命令进行分隔，指定每行最多包含默认值50个字符。
fold -w 50 file.txt
# fold command in Linux wraps each line in an input
# file to fit a specified width and prints it to the
#  standard output. By default, it wraps lines at a
# maximum width of 80 columns but this is configurab
# le. To fold input using the fold command pass a fi
# le or standard input to the command.

使用fold命令进行分隔，并使用-s选项用于分隔空格上的行，以便不打断单词。
fold -w 50 -s file.txt
# fold command in Linux wraps each line in an input
# file to fit a specified width and prints it to
# the standard output. By default, it wraps lines
# at a maximum width of 80 columns but this is
# configurable. To fold input using the fold
# command pass a file or standard input to the

1.在scala中，对集合的fold操作：
val l=List(1,2,3)
val res=l.fold(10)(_+_)
结果res为16  这里的10为整个集合的初始值，只使用了一次
2.spark中rdd
val a=sc.makeRDD(List(1,2,3))
val res=a.fold(10)(_+_)
结果res为46 这里的10为集合中每个元素的初始值，每个元素在调用函数_+_之前都被加了10
注意区别
foldByKey同fold，但是前者反悔的是一个rdd，属于转换操作，后者返回值，属于行动操作
val b=sc.parallelize(List((1,2),(3,4),(3,6)))
val res=b.foldByKey(10)(_+_)
res foreach println
结果为（1,12） （3，30）
