我只是使用cron编写用于自动化目的的perl程序
我的cron是
*/30 * * * * perl /path/to/cron.pl
cron.pl
#!/usr/bin/perl
use strict;
use warnings;
`/usr/bin/perl /path/to/run.pl`;
在代码中我使用back tick运行其他perl程序。
run.pl
#!/usr/bin/perl
use strict;
use warnings;
open(FL,">text.txt") or die $!;
print FL "hi";
close FL;
每当我运行cron.pl时，它都会创建“text.txt”文件。但是cron运行程序cron.pl正在运行但是run.pl还没有运行。谁能告诉我在代码中做错了什么？

行必须包含可执行文件的完整路径！
