Summary | 0000544: extend awk delete statement to delete entire array | ||||||
Description |
The awk "delete" statement is currently defined as removing an individual array element. To delete an entire array, a delete statement must be called for each element of the array, typically in a loop. At least gawk, mawk, BWK awk, Solaris /usr/xpg4/bin/awk, and BusyBox awk, which collectively comprise the vast majority of installed awk implementations, provide an extension that allows the deletion of all elements of an array with a single delete statement, specifying only the array name without subscripts (e.g., "delete ARRAY" instead of "for(i in ARRAY) delete ARRAY[i]")). Besides the advantage of syntactic compactness, it allows an implementation to more easily optimize the deletion of all array elements (e.g., the gawk manual states "Using this version of the delete statement is about three times more efficient than the equivalent loop that deletes each element one at a time."). |
||||||
Desired Action |
Extend the awk syntax to allow delete ARRAY where ARRAY is an array name. |
