无法将 git 分支命令的 output 捕获到 bash 变量中

Question

Very wierd. If I run this command interactively, I see the expected result:

    git branch --contains c46b341b72509a02ee1c1a489a7f9b37d477c4f5
    * v2Tunnel

But if I try to capture this in a variable, what gets captured is the names of some (but not all) files in the current folder, followed by the expected branch name (v2Tunnel is not a file in my directory)

    CCC=$(git branch --contains c46b341b72509a02ee1c1a489a7f9b37d477c4f5)
    # OR
    CCC=`git branch --contains c46b341b72509a02ee1c1a489a7f9b37d477c4f5`

    echo $CCC
    IWiNS README.md cicommit citest v2Tunnel

Other git commands to not have this result:

    CCC=`git rev-parse --abbrev-ref HEAD`
    echo $CCC
    v2Tunnel

Answer 1

You captured * v2Tunnel in CCC so when you do echo $CCC the shell interprets that * and lists local files.

To prevent shell to interpret * use double quotes:

echo "$CCC"
