在 fish shell 中执行我自己写一个 shell 脚本时，报错
> lazy
Failed to execute process '/home/zhongwei/bin/lazy'. Reason:
exec: Exec format error
The file '/home/zhongwei/bin/lazy' is marked as an executable but could not be run by the operating system.
lazy 中的代码很简单，就是一行，为了我自己偷懒时使用
> cat ~/bin/lazy
git commit -a -m"update"
我猜测是 fish shell 中必须指定 shell 名称。
修改成
> cat ~/bin/lazy
#!/bin/bash
set -e # or use "set -o errexit" to quit on error.
set -x # or use "set -o xtrace" to print the statement before you execute it.
git commit -a -m"update"
就一切正常了。
