Call a bash script from a perl script
提问by iDev
I am trying a code in perl script and need to call another file in bash. Not sure, which is the best way to do that? can I directly call it using system() ? Please guide/ show me a sample way.
我正在尝试用 perl 脚本编写代码，需要在 bash 中调用另一个文件。不确定，这是最好的方法吗？我可以使用 system() 直接调用它吗？请指导/向我展示一个示例方法。

If you just want run you script you can use backticks or system:
如果你只想运行你的脚本，你可以使用反引号或系统：
$result = `/bin/bash /path/to/script`;
or
或者
system("/bin/bash /path/to/script");
If your script produces bug amount of data, the best way to run it is to use open + pipe:
如果您的脚本产生大量数据，运行它的最佳方法是使用 open + pipe：
if open(PIPE, "/bin/bash /path/to/script|") {
while(<PIPE>){
}
}
else {
# can't run the script
die "Can't run the script: $!";
}

You can use backticks to execute commands:
您可以使用反引号来执行命令：
$command = `command arg1 arg2`;
There are several other additional methods, including system("command arg1 arg2")to execute them as well.
还有其他几种附加方法，包括system("command arg1 arg2")执行它们。

I solved my first problem according to Why doesn't "cd" work in a bash shell script?:
我根据 为什么“cd”在 bash shell 脚本中不起作用？：
alias proj="cd /home/tree/projects/java"
