[Linux][ubuntu][Perl]bad interpreter: No such file or directory

在windows 系统上 写了个perl脚本来给 android 手机做压力测试。但是放到linux 系统上work 起来不是很友好。

该脚本放到 ubuntu 1204 64bit 系统上执行时会报如下错误：

$ ./adb_script.pl

bash: ./adb_script.pl: /usr/bin/perl^M: bad interpreter: No such file or directory

然后对该脚本用 dos2unix 进行格式转化，

$ dos2unix ./adb_script.pl

The program 'dos2unix' is currently not installed.  To run 'dos2unix' please ask your administrator to install the package 'dos2unix'

发现 ubuntu 默认未安装 dos2unix

$ sudo apt-get install dos2unix

安装完 dos2unix 后，重新执行

然后再执行脚本文件，脚本完美的在ubuntu上执行。
