Re: generating a list of identical elements

You can do this with the x operator as well:

perl -e '$x="ab"; $n= 20; @f= ($x) x $n; print join "|",@f;'
#prints
ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab|ab

Great!!! I had not expected this possibility, so I did not look up the definition of this operator. My fault, and thank you for telling me! -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
