bash - Bash：for循环中的错误替代错误-git标签

问题描述

我正在尝试执行从 SVN 到 GIT 的迁移，git svn clone ..并且一切正常。

现在我需要使用此命令将 SVN 中的标签转换为 git 中的真实标签

for t in $(git for-each-ref --format='%(refname:short)' refs/remotes/origin/tags) 
do 
    git tag ${t/origin\/tags\//} $t - #BAD substitution error - need to fix
    git branch -D -r $t
done

如果我在命令行中运行此脚本，它可以工作，但如果我在 shell 脚本中运行此脚本，它将失败并出现“错误替换错误”。这里有什么建议吗？

完整的脚本在这里：

#!/bin/bash

## Modificed script - Fork from https://github.com/MPDFT/svn-to-git

####### Project name
PROJECT_NAME="" #Example - Digisharp
SVN_USERNAME="" #Example - adys
GIT_USERNAME="" #Example - adys

####### SVN
# SVN repository to be migrated

####### GIT
# Git repository to migrate - IMPORTANT! YOU MUST INCLUDE YOUR USERNAME AND PASSWORD(PAT TOKEN FOR AZURE) 
# We need this to automate the git push without having it asking you for password
GIT_URL="" #Example -

for t in $(git for-each-ref --format='%(refname:short)' refs/remotes/origin/tags) 
do 
    #git tag ${t/origin\/tags\//} $t - BAD substitution error - need to fix
    git branch -D -r $t
done

for b in $(git for-each-ref --format='%(refname:short)' refs/remotes)
do 
    git branch $b refs/remotes/$b
    git branch -D -r $b
done
echo -e "${LIGHT_GREEN} [RUN] Step 05/05 [RUN] git push ${NC}"
git push origin --all
git push origin --tags
echo "Successful - The git repository is now available in" $GIT_URL

我运行命令sh migration.sh

标签： bashgit

解决方案

你是在用类似的东西执行你的脚本/bin/sh /path/to/script.sh吗？

${t/origin\/tags\//}在 bash 中可用，但与 POSIX shell 不兼容，您可能会成功地将其更改为：

echo "$t" | sed 's~origin/tags/~~'

我强烈建议您使用 shellcheck 对脚本进行linting，因为您遇到了一些潜在的错误。
