bash-通过bash为多个git存储库切换git协议

在linux上，有一些git repo，其

.git/config

包含以下3行：

[remote "origin"] url = git@github-eo:eric/workspace.git # url = https://eric@github.com/eric/workspace.git [远程“源”] url=git@github-eo:eric/workspace.git #url=https://eric@github.com/eric/workspace.git （提示：最后两行以制表符开头。）

问题是：

#!/bin/bash

# repo array,
repo_arr=(
    "/mnt/star/git_repository/workspace" 
    "/media/ERIC/node"
    "/mnt/star/workplace/eclipse_j2ee_workplace/eric"
)

protocol="null"

url_prefix_comment=""
url_prefix_uncomment=""

repo_count=0

# read protocol,
if [ $# -ge 1 ]; then
    protocol=$1
fi

# check protocol,
if [ $protocol == "ssh" ]; then
    url_prefix_comment="https"
    url_prefix_uncomment="git"
elif [ $protocol == "https" ]; then
    url_prefix_comment="git"
    url_prefix_uncomment="https"
else
    echo "invalid protocol: $protocol"
    exit 1;
fi


# switch protocol for repo in array,
for i in "${!repo_arr[@]}"; do 
    if [ -d "${repo_arr[$i]}" ]; then
        sed -i "s/^\turl = $url_prefix_comment/\t# url = $url_prefix_comment/g" "${repo_arr[$i]}/.git/config"
        sed -i "s/^\t# url = $url_prefix_uncomment/\turl = $url_prefix_uncomment/g" "${repo_arr[$i]}/.git/config"

        repo_count=$(expr $repo_count + 1)
    else
        echo "non exists repo: ${repo_arr[$i]}"
    fi
done

echo "Done, switch to protocol [$protocol], repo count: {$repo_count}."

exit 0

• 我想通过bash将

  #

  从第三行移动到第二行，可能是通过sed，还可以将其移回。我的意思是触发这两行，如何在bash中调用sed

---

@更新： 通过参数选择协议以编写脚本：

#!/bin/bash

# repo array,
repo_arr=(
    "/mnt/star/git_repository/workspace" 
    "/media/ERIC/node"
    "/mnt/star/workplace/eclipse_j2ee_workplace/eric"
)

protocol="null"

url_prefix_comment=""
url_prefix_uncomment=""

repo_count=0

# read protocol,
if [ $# -ge 1 ]; then
    protocol=$1
fi

# check protocol,
if [ $protocol == "ssh" ]; then
    url_prefix_comment="https"
    url_prefix_uncomment="git"
elif [ $protocol == "https" ]; then
    url_prefix_comment="git"
    url_prefix_uncomment="https"
else
    echo "invalid protocol: $protocol"
    exit 1;
fi


# switch protocol for repo in array,
for i in "${!repo_arr[@]}"; do 
    if [ -d "${repo_arr[$i]}" ]; then
        sed -i "s/^\turl = $url_prefix_comment/\t# url = $url_prefix_comment/g" "${repo_arr[$i]}/.git/config"
        sed -i "s/^\t# url = $url_prefix_uncomment/\turl = $url_prefix_uncomment/g" "${repo_arr[$i]}/.git/config"

        repo_count=$(expr $repo_count + 1)
    else
        echo "non exists repo: ${repo_arr[$i]}"
    fi
done

echo "Done, switch to protocol [$protocol], repo count: {$repo_count}."

exit 0

实际上，我将为脚本提供一个参数，它应该是

ssh

或

https

，该参数将决定取消注释哪一行，以及注释哪一行，如果两个协议之一的行不存在，则忽略它

顺便说一下，我只需要sed部分来修改这两行，我可以编写bash的其他部分，以节省您的时间

我想这样做的原因：

#!/bin/bash

# repo array,
repo_arr=(
    "/mnt/star/git_repository/workspace" 
    "/media/ERIC/node"
    "/mnt/star/workplace/eclipse_j2ee_workplace/eric"
)

protocol="null"

url_prefix_comment=""
url_prefix_uncomment=""

repo_count=0

# read protocol,
if [ $# -ge 1 ]; then
    protocol=$1
fi

# check protocol,
if [ $protocol == "ssh" ]; then
    url_prefix_comment="https"
    url_prefix_uncomment="git"
elif [ $protocol == "https" ]; then
    url_prefix_comment="git"
    url_prefix_uncomment="https"
else
    echo "invalid protocol: $protocol"
    exit 1;
fi


# switch protocol for repo in array,
for i in "${!repo_arr[@]}"; do 
    if [ -d "${repo_arr[$i]}" ]; then
        sed -i "s/^\turl = $url_prefix_comment/\t# url = $url_prefix_comment/g" "${repo_arr[$i]}/.git/config"
        sed -i "s/^\t# url = $url_prefix_uncomment/\turl = $url_prefix_uncomment/g" "${repo_arr[$i]}/.git/config"

        repo_count=$(expr $repo_count + 1)
    else
        echo "non exists repo: ${repo_arr[$i]}"
    fi
done

echo "Done, switch to protocol [$protocol], repo count: {$repo_count}."

exit 0

我想这样做，因为有时由于网络或github错误，

ssh

无法工作，我不知道，当时我需要将所有git repo从

ssh

切换到

https

，但是当

ssh

工作正常时，我会使用它，因为我不需要每次输入密码

我还问过为什么ssh有时不工作，但没有解决这个问题，所以我必须编写一个脚本，用一个命令来帮助触发它

总结： 感谢您的回答和评论，我将把解决方案总结如下

解决方案：

#!/bin/bash

# repo array,
repo_arr=(
    "/mnt/star/git_repository/workspace" 
    "/media/ERIC/node"
    "/mnt/star/workplace/eclipse_j2ee_workplace/eric"
)

protocol="null"

url_prefix_comment=""
url_prefix_uncomment=""

repo_count=0

# read protocol,
if [ $# -ge 1 ]; then
    protocol=$1
fi

# check protocol,
if [ $protocol == "ssh" ]; then
    url_prefix_comment="https"
    url_prefix_uncomment="git"
elif [ $protocol == "https" ]; then
    url_prefix_comment="git"
    url_prefix_uncomment="https"
else
    echo "invalid protocol: $protocol"
    exit 1;
fi


# switch protocol for repo in array,
for i in "${!repo_arr[@]}"; do 
    if [ -d "${repo_arr[$i]}" ]; then
        sed -i "s/^\turl = $url_prefix_comment/\t# url = $url_prefix_comment/g" "${repo_arr[$i]}/.git/config"
        sed -i "s/^\t# url = $url_prefix_uncomment/\turl = $url_prefix_uncomment/g" "${repo_arr[$i]}/.git/config"

        repo_count=$(expr $repo_count + 1)
    else
        echo "non exists repo: ${repo_arr[$i]}"
    fi
done

echo "Done, switch to protocol [$protocol], repo count: {$repo_count}."

exit 0

• 使用

  bash

  和

  sed

  ，查看Eric Wang（我）的答案。它适用于linux，我想mac可能需要对

  选项卡进行一些修改，以匹配，windows可能无法使用它

• 使用

  bash

  和

  awk

  ，参见

  anubhava

  的答案
• 定义多个远程，1个用于ssh，1个用于https，然后通过选择远程来选择协议，请参见William Pursell的问题注释。我想这将适用于所有系统
• 对另一个指定协议行的文件使用

  [包括]

  ，并在需要时更改软链接，可以编写shell脚本来帮助切换软链接，而不是更改文件内容，请参见

  gniourf\u gniourf

  的问题注释。我想这至少适用于类unix系统

---

awk

可能是更好的选择：

awk -v kw='(https|ssh):' 'p ~ /^\turl/ && $0 ~ kw && $0 ~ /^\t#[[:blank:]]*url/ {
   sub(/^\t/, "\t# ", p)
   sub(/^\t*#[[:blank:]]*/, "\t")
}
p!="" {
   print p
}
{
   p=$0
}
END {
   print p
}' file

[remote "origin"]
    # url = git@github-eo:eric/workspace.git
    url = https://eric@github.com/eric/workspace.git

我刚刚通过

sed

了解了如何做到这一点，下面是脚本：

---

代码 git\u协议\u交换机。sh:

#!/bin/bash

# repo array,
repo_arr=(
    "/mnt/star/git_repository/workspace" 
    "/media/ERIC/node"
    "/mnt/star/workplace/eclipse_j2ee_workplace/eric"
)

protocol="null"

url_prefix_comment=""
url_prefix_uncomment=""

repo_count=0

# read protocol,
if [ $# -ge 1 ]; then
    protocol=$1
fi

# check protocol,
if [ $protocol == "ssh" ]; then
    url_prefix_comment="https"
    url_prefix_uncomment="git"
elif [ $protocol == "https" ]; then
    url_prefix_comment="git"
    url_prefix_uncomment="https"
else
    echo "invalid protocol: $protocol"
    exit 1;
fi


# switch protocol for repo in array,
for i in "${!repo_arr[@]}"; do 
    if [ -d "${repo_arr[$i]}" ]; then
        sed -i "s/^\turl = $url_prefix_comment/\t# url = $url_prefix_comment/g" "${repo_arr[$i]}/.git/config"
        sed -i "s/^\t# url = $url_prefix_uncomment/\turl = $url_prefix_uncomment/g" "${repo_arr[$i]}/.git/config"

        repo_count=$(expr $repo_count + 1)
    else
        echo "non exists repo: ${repo_arr[$i]}"
    fi
done

echo "Done, switch to protocol [$protocol], repo count: {$repo_count}."

exit 0

叫它

---

它能做什么 它将有助于为bash数组中列出的所有repo切换协议。 当然，需要手动为每个回购协议添加2行2协议

---

干杯：}
什么是输入文件只有一行，即

\turl=git@github-eo:ericoudesu/linux_workspace.git

？还需要评论吗？@anubhava我更新了问题，请看。也许，你只是想介绍另一个遥控器？我的意思是，一个远程设备专用于只读

https://

，另一个远程设备专用于r/w

ssh://

？@user3159253我更新了问题，解释了我为什么需要脚本，请参考。您是否尝试过编写

sed

命令来完成您想要的任务？我测试过，似乎未注释的行在选项卡后面有一个空格，你能帮我把它去掉吗？非常感谢，我认为这是一个解决办法。但我刚刚在sed中找到了如何做到这一点，请参阅我的另一个答案。
