我正面临一个非常奇怪的问题。 我在运行后台运行perl 5.10.1上运行Squeeze服务器上的脚本。 当我从控制台运行脚本时,它完美的工作。 但是当我试图用cron运行它时,会出现像“我的var,我的var2,我的var3等错误”的错误。 还有它说有语法错误,由于缺less“(”。但是,如果我从控制台运行它,它的工作原理。
这里脚本的开始和它的抱怨。
##!/usr/lib/perl #BACKUPPEITOR 2012 #IT DOES BACKUPS OF EVERTHING AND USE RSYNC #TO UPLOAD THEM TO HIDRIVE-STRATO #AND KEEP YOU POSTED OF IF SOMETHING WENT WRONT #Uses #use strict; #use warnings; use Net::SMTP; use POSIX 'strftime'; use MIME::Lite; #Variables my $seconds = strftime '%H:%M:%S-%d%m%y', localtime; my $time = strftime '%H:%M:%S_-_%d_%m_%Y', localtime; my $tLog = strftime '%d%m%Y', localtime; my $foMy = "/home/backup/data/mysql/"; my $foPsql = "/home/backup/data/postgres/"; my $uMy = 'USER'; my $pMy = 'SECRET'; my @mysql_re = ""; my @psql_status =""; my @esanum_re =""; my $foEsanum = "/home/folder/"; my $fMy =""; my $logF = "/home/backup/log/backuplog_$tLog.log"; #Set mail config MIME::Lite->send('smtp','mail.mailserver.org', Timeout=>60,AuthUser=>'SECRET', AuthPass=>'SECRET');
而当我把它作为cronjob在日志文件中运行时,

你看? 它不能find我的variables,为什么? 现在,perl -V和uname -a给所有的te信息。

第一行告诉内核哪个程序用于该文件 – 但只有当它看起来像这样:
#!/path/to/interpreter
如果没有,就像你的情况一样,那么shell将继续执行所述文件并将其解释为shell脚本。 因此,它认为my
和use
的程序来执行,无法执行它们,并打印你看到的错误。
如果使用perl /path/to/your/script
而不是简单的/path/to/your/script
那么内核就不会涉及到,而第一行实际上可能看起来不一样。
它试图将Perl脚本作为shell脚本运行,这意味着它不会将文件的第一行识别为shebang。
为了解决这个问题,你需要从这里改变脚本的第一行:
##!/usr/lib/perl
对此:
#!/usr/lib/perl
我相信你的脚本的第一行
##!/ usr / lib中/ perl的
应该是(替换/ lib / with / bin /)
#!的/ usr / bin中/ perl的
/usr/lib/perl
通常是一个目录。 导致perl脚本作为sh
脚本运行。 由于不明白Perl的语法,把你所有的错误。
