跟java里的split函数的用法是很相像的,举例如下: Theawkfunctionsplit(s,a,sep) splits a stringsinto anawkarrayausing the delimitersep. set time = 12:34:56 set hr = `echo $time | awk '{split($0,a,":" ); print a[1]}'` # = 12 set sec = `echo $time | awk '{split($0,a,":...
split(s, a [, r]) Splits the string s into the array a on the regular expression r, and returns the number of fields. If r is omitted, FS is used instead. The array a is cleared first. Splitting behaves identically to field splitting, described above. tolower(str) Returns a copy ...

The idea of "numeric string" only applies to fields, getline input, FILENAME, ARGV elements, ENVIRON elements and the elements of an array created by split() that are numeric strings. The basic idea is that user input, and only user input, that looks numeric, should be treated that way...
The "split()" function has the syntax: split(,,[]) This function takes a string with n fields and stores the fields into array[1], array[2], ... , array[n]. If the optional field separator is not specified, the value of FS (normally "white space", the space and tab characters...
split(string, array [, fieldsep [, seps ] ]) Divide string into pieces separated by fieldsep and store the pieces in array and the separator strings in the seps array. The first piece is stored in array[1], the second piece in array[2], and so forth. The string value of the th...
n = split(string, array, regexp) Splits the string into fields. regexp is a regular expression giving the field separator string for the purposes of this operation. This function assigns the separate fields, in order, to the elements of array; subscripts for array begin at 1. awk discards...
