今天写脚本遇到Can't use string ("bond2 Link encap:InfiniBand ") as a symbol ref while "strict refs" in use at test.pl line 的错误函数
google了一下,发现stackoverflow有这样的错误,其中有一个是缺乏一个分号致使的google
例如:spa
open (FILE, "ifconfig | "); while (<FILE>) { my $line = $_; print $line sleep 1; }
运行以后是这个错误:code
Ifconfig is obsolete! For replacement check ip.
Can't use string ("bond2 Link encap:InfiniBand ") as a symbol ref while "strict refs" in use at test.pl line 15, <FILE> line 1blog
我仔细检查我本身的代码,并未发现缺乏分号,运行以后依然报错ip
个人代码是:就是运行data命令,把结果写到data.log中string
#!/usr/bin/perl use strict; sub TIME { my $time=readpipe("date"); return "$time\n"; } open(TIME,">date.log") or die "$!\n"; print TIME &TIME; close(TIME);
运行以后是这个样子pip
Can't use string (XXXXX) as a symbol ref while "strict refs" in use at test.pl line 8.class
并不是缺乏分号,我又仔细看了,发现函数名和文件句柄名都是TIME,就把文件句柄名改为别的,而后脚本就能够正常运行test
原来perl 文件句柄和函数不能使用相同的名字,之后再遇到相似的错误,注意检查一下文件名和分号
