Git从Shell脚本中提取

我试图从bash脚本更新git repo，但遇到了一些麻烦。如果git pull之后没有其他行或字符，但如果我说have，我可以运行git pull，让它工作

#!/bin/bash
git pull
echo "test"

然后我得到

' is not a git command. See 'git --help'.

Did you mean this?
        pull

在终端中，您必须首先像Etan提到的那样执行dos2unix，而不是实际执行

git pull

。如果执行相反的操作（即unix2dos），则可以重新生成相同的错误

$cat 1.sh

#!/bin/bash

git pull
echo ----

如上所述，gitpull命令工作正常，但有一条有效的错误消息，在pull之后并没有像我第一次做的那个样提到repo。这意味着git是存在的（如果您选择了哪个git，您将看到有效的git可执行文件位置）

$unix2dos.exe./1.sh

#!/bin/bash

现在，我的文件是DOS格式的（我在Linux机器上运行脚本）。你在用Cygwin吗

$/1.sh

#!/bin/bash

git pull

好的，使用dos2unix将其转换回Unix行结束字符

$dos2unix.exe./1.sh

#!/bin/bash

git pull

它按预期工作

或者尝试使用bash-x运行该文件是否有DOS换行符？在该脚本上运行

dos2unix

是否有帮助？如果您有基于UNIX的系统，请使用apt get install git，如果您有基于Windows的系统，请手动安装git。正如@EtanReisner所建议的，您可以使实际运行的

git pull\r

@Ioan他们显然安装了git，因为他们从git收到了错误消息。
