Question

我有一个git pre-push hook，它调用一个名为pre-push.sh的shell脚本，如此

#!/bin/bash

#Fail if one script fails and print all info to console
set -ex

#Font variables
underline=`tput smul`
nounderline=`tput rmul`

#Run grunt
grunt;

#Make sure there is only one commit being pushed
printf "\n${underline}Validating Number of Commits${nounderline}\n";
src/scripts/hooks/pre-push/countCommits.sh;

计数提交就是这样

#!/bin/bash


confirm () {
    # call with a prompt string or use a default
    read -r -p "${1:-Are you sure? [y/N]} " response
    case $response in
        [yY][eE][sS]|[yY]) 
            true
            ;;
        *)
            false
            ;;
    esac
}
#This script counts the number of commits being pushed and fails if it is greater than 1 commit being pushed
countCommits(){
    NUMBER_OF_COMMITS=`git rev-list @{u}.. | wc -l`
    if [ "$NUMBER_OF_COMMITS" -gt "1" ]; then
        return 1
        #exit 1
     else
        return 0
    fi

}


if countCommits; then
    printf "\e[0;32mDone, without errors.\e[0m"
else
    printf "$NUMBER_OF_COMMITS commits were pushed. We recommend pushing only 1 commit."
    if confirm "$NUMBER_OF_COMMITS commits were found. We recommend pushing only 1 commit. Do you wish to continue? [y/N]"; then
        :
    else
        printf "Please squash your commits by running \e[1;34m'git rebase -i'\e[0m\n"
        exit 1
    fi
fi

直接调用pre-push.sh时，它可以正常工作，即如果用户有超过1次提交，则等待用户说'y'或'n'。但是，当我将它用作预推钩时，它不会等待用户提示并继续沿着无路径

直接调用pre-push.sh

+ src/scripts/hooks/pre-push/countCommits.sh
       5 commits were pushed. We recommend pushing only 1 commit.       5 commits were found. We recommend pushing only 1 commit. Do you wish to continue? [y/N] n
Please squash your commits by running 'git rebase -i'

进行git推送时

+ src/countCommits.sh
       5 commits were pushed. We recommend pushing only 1 commit.Please squash your commits by running 'git rebase -i'
error: failed to push some refs

如何获取git钩子以允许用户输入？

来自`man githooks

   Information about what is to be pushed is provided on the hook's standard input with lines of the form:

       <local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF

因此脚本不会等待您的手动输入，它只是使用第一行，这肯定与您的模式不符。

除了提示是否继续之外，您应该告诉用户如果他们真的想要推送，他们应该使用--no-verify参数重新运行命令。

git hook不使用输入流
