Shell script: variable scope in functions -

-
i wrote quick shell script emulate situation of xkcd #981 (without hard links, symlinks parent dirs) , used recursive function create directories. unfortunately script not provide desired result, think understanding of scope of variable $count wrong. how can make function use recursion create twenty levels of folders, each containing 3 folders (3^20 folders, ending in soft links top)? #!/bin/bash echo "generating folders:" toplevel=$pwd count=1 gen_dirs() { in 1 2 3 dirname=$random mkdir $dirname cd $dirname count=$(expr $count + 1) if [ $count < 20 ] ; gen_dirs else ln -s $toplevel "./$dirname" fi done } gen_dirs exit try (amended version of script) — seems work me. decline test 20 levels deep, though; @ 8 levels deep, each of 3 top-level directories occupies 50 mb on mac file system. #!/bin/bash echo "generating folders:" toplevel=$pwd gen_dirs...

regex - What it the fastest way to check if a string consists of three or more dashes in php? -

-
is regex way? slow? something this? preg_match("/^(\-){3,}/", $string); only dashes if want string only dashes, , there must 3 or more: $match = (preg_match('/^-{3,}$/', $string) === 1); another way without regex seems 25% slower ( isset beats strlen ): $match = (count_chars($string, 3) === '-' && isset($string[2])); adjacent dashes if want 3 or more dashes in row, there may other characters (e.g. foo---bar ): $match = (strpos($string, '---') !== false); some dashes if want 3 or more dashes anywhere (e.g. -foo-bar- ): $match = (substr_count($string, '-') >= 3);
