I realize that awk has associative arrays, but I wonder if there is an awk equivalent to this:

The obvious workaround is to just say:
array[$new_element] = $new_element However, this seems less readable and more hackish than it needs to be.

AWK has associative arrays and one of the best thing about it is – the indexes need not to be continuous set of number; you can use either string or number as an array index. Also, there is no need to declare the size of an array in advance – arrays can expand/shrink at runtime.
We can create an array using the Array module and then apply the append() function to add elements to it.
The awk language provides one-dimensional arrays for storing groups of related strings or numbers. Every awk array must have a name. Array names have the same syntax as variable names; any valid variable name would also be a valid array name.
8 Arrays in awk An array is a table of values called elements. The elements of an array are distinguished by their indices. Indices may be either numbers or strings.
I don't think an array length is immediately available in awk (at least not in the versions I fiddle around with). But you could simply maintain the length and then do something like this:
array[arraylen++] = $0; And then access the elements it via the same integer values:
for ( i = 0; i < arraylen; i++ ) print array[i]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
