Test to determine if git clone command succeeded
提问by bhadram
I tried to clone the git repository by passing the username, password. That was successful.
我试图通过传递用户名和密码来克隆 git 存储库。那是成功的。
But what my intention is that I want to know whether the git clone command executed or not. If not, I would like to handle such kind of errors in shell script itself.
但我的意图是我想知道 git clone 命令是否执行。如果没有，我想在 shell 脚本本身中处理此类错误。
My working shell script:
我的工作 shell 脚本：
cd ..
git clone https://username:[email protected]/username/repositoryname.git
cd repositoryname
git checkout branchname1
cd ..
mv repositoryname newfoldername
git clone https://username:[email protected]/username/respositoryname.git
cd repositoryname
git checkout branchname2
cd ..
mv repositoryname newfoldername
How do I test, in the script, whether these steps were successful?
如何在脚本中测试这些步骤是否成功？

The return value is stored in $?. 0 indicates success, others indicates error.
返回值存储在 $? 中。0 表示成功，其他表示错误。
some_command
if [ $? -eq 0 ]; then
echo OK
else
echo FAIL
fi
I haven't tried it with git, but I hope this works.
我还没有用 git 试过，但我希望这有效。

This one should work (Just put your script at the place marked "--- your script here ---" below):
这个应该可以工作（只需将您的脚本放在下面标记为“---您的脚本在这里---”的地方）：
#!/bin/bash
# call your script with set -e to stop on the first error
bash <<EOF
set -e
--- your script here ---
EOF
# test status: I don't want this part to stop on the first error,
# and that's why use the HERE document above to wrap a sub-shell for "set -e"
if [ $? -eq 0 ]; then
echo success
else
echo fail
fi
Alternatively, HERE document can be replaced by:
或者，HERE 文档可以替换为：
(
set -e
--- your script here ---
)
