$ awk 'BEGIN { str = "One,Two,Three,Four" split(str, arr, ",") print "Array contains following values" for (i in arr) { print arr[i] } }' 输出结果为: Array contains following values One Two Three Four tolower( String ) 返回String 参数指定的字符串,字符串中每个大写字符将更改为...
split(String, Array [, Sep]) 将由String 参数指定的输入字段分割成多个元素并存储到 Array 数组中,每个数组元素对应一个字段。字段之间由 Sep 参数指定的分隔符隔开。如果 Sep 参数未指定,则使用空格作为分隔符。返回分割的数量。 tolower(String) 将String 参数指定的字符串转换成小写形式,并返回结果。 toupper...
awk 针对当前输人记录$0 自动提供了方便的分割为字1, $}, …、$NF ,也可以函数来做:split(string, array, regexp) 将string 切割为片段,并存储到array 里的连续元素。在数组里,片段放置在匹配正则表达式regexp 的子字符串之间。如果regexp 省略,则使用内建字段分隔字符FS 的当前默认值。函数会返回array 里...
$ awk '{ print toupper("test"), tolower("TEST") }' split函数可按给定的分隔符把字符串分割为一个数组。如果分隔符没提供,则按当前FS值进行分割。格式如下: split( string, array, field separator ) split( string, array ) 实例: $ awk '{ split( "20:18:00", time, ":" ); print time[...
to split string (much as FS can be a regexp describing where to split input records; see Regexp Field Splitting). If fieldsep is omitted, the value of FS is used. split() returns the number of elements created. seps is a gawk extension with seps[i] being the separator string ...
Split String into Arrays Basic String Splitting Suppose you have a line of text that lists different services and their statuses, separated by commas: "Internet:Active,TV:Inactive,Phone:Active" You want to split this string into an array, where each service and its status is an element of th...
N split(string,store,delim) 根据分界符delim,分解string为store的数组元素 N sprintf(format,variable) 返回一个包含基于format的格式化数据,variables是要放到串中的数据 G strftime(format,timestamp) 返回一个基于format的日期或者时间串,timestmp是systime()函数返回的时间 ...
Convert string to columns - Data Frame I have the data frame below and I intend to use it for a ML regression model. I want to transform features into separate columns on the frame with a 1 if feature exists or 0 if it doesn't. This is to ... ...
split( String, A, [Ere] ) 将 String 参数指定的参数分割为数组元素 A[1], A[2], . . ., A[n],并返回 n 变量的值。此分隔可以通过 Ere 参数指定的扩展正则表达式进行,或用当前字段分隔符(FS 特殊变量)来进行(如果没有给出 Ere 参数)。除非上下文指明特定的元素还应具有一个数字值,否则 A 数组中...
