deleting elements in array in a loop Perl -


i want make loop go through elements in 1 array (@array1), , if same element found in array (@array2), want value third array (@array3) same index added first array , deleted third array. tried way, line if-statement runs on unitialized values, , loops forever.

    foreach $elem1 (@array1){         $i = 0;         while ($i < scalar @array2){             if($array2[$i]==$elem1){                 push (@array1, $array3[$i]);                 delete $array2[$i];             }             else{                 $i++;             }         }     }

the problem not increment $i if element matches. delete else.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
