./富
执行富
,如果它是标记为可执行文件,并有适当的shebang行(或者是一个ELF二进制)。这将在一个新的进程来执行。
./foo
executed foo
if it's marked as executable and has a proper shebang line (or is an ELF binary). It will be executed in a new process.
。 ./foo
或。富
加载在电流的外壳脚本。它等于源富
. ./foo
or . foo
loads the script in the current shell. It is equal to source foo
随着你的榜样code你需要,如果你想导出的变量在你的shell可使用第二种方式。
With your example code you need to use the second way if you want the exported variables to be available in your shell.
