i have an regx question. i have the array contents, now i want to
remove the first 2 characters (fc) of each element in the array and
store it in a second array ex: @array2
@array ="fc20/1, fc30/22, fc40/3, fc20/1";
output
@array2 ="20/1, 30/22, 40/3, 20/1";
please advice.
It would be helpful if you posted actual Perl code.
Try:
# remove the first 2 characters from every element of the array
my @array2 = map { s/^..//msx } @array1;
This code is wrong in two respects:
1. the map clause will return the return value of the s/// subtitution and will
modify
the original array in place:
Correct.
2. A minor problem of semantics is that under /m "^" matches any start of line,
Only if the /g option is also used AND the strings have embedded newlines.
so \A is preferable.
Without the /g option ^ and \A do exactly the same thing.
