zsh 中的 git cat-file -p master^{tree} 错误

Question

In gitscm.org documentation, under git objects chapter, it uses the command below, but trying it out gives me "zsh: no matches found: master^{tree}". Any idea what's incorrect?

git cat-file -p master^{tree}

Answer 1

I've found that when specifying those more tricky git revision parameters, I have to quote them

git cat-file -p "master^{tree}"

while leaving out the " fails.

This behavior and and the reason for it varies with the platform:

• On Windows, in PowerShell and cmd.exe, the ^ character is used for escaping. So, as an alternative, you can write git cat-file -p master^^{tree}
• In zsh the ^ character is used for globbing
• In bash the command works without quotes

(thanks to Wumpus Q. Wumbley and kostix for explanations)

Answer 2

You can run noglob whatever if you want to run whatever without globbing. I have it defined as an alias for rake , for instance.

Answer 3

在 Windows 中执行该步骤之前需要克隆项目。

Answer 4

The various possible cases for this error:

Depending on what shell you use, you may encounter errors when using the master^{tree} syntax.

In CMD on Windows, the ^ character is used for escaping, so you have to double it to avoid this: git cat-file -p master^^{tree}. When using PowerShell, parameters using {} characters have to be quoted to avoid the parameter being parsed incorrectly: git cat-file -p 'master^{tree}'.

If you're using ZSH, the ^ character is used for globbing, so you have to enclose the whole expression in quotes: git cat-file -p "master^{tree}".

As villasv pointed out that: " If you do get "Not a valid object name master^{tree}", make sure you have at least one commit done. The master branch does not exist yet immediately after git init. – villasv " Since The master^{tree} syntax specifies the tree object that is pointed to by the last commit on your master branch as referenced to git object After making commit to current change, git cat-file -p 'master^{tree}' can be executed.
