我阅读手册页,但没有一个例子或解释.这是否捕获标签？任何有关这方面的文件？

编辑：具体如何做数据= $(cat)允许它运行这个钩子脚本？

#!/bin/bash 

# Runs all executable pre-commit-* hooks and exits after,# if any of them was not successful. 
# 
# Based on 
# http://osdir.com/ml/git/2009-01/msg00308.html 

data=$(cat) 
exitcodes=() 
hookname=`basename $0` 

# Run each hook,passing through STDIN and storing the exit code. 
# We don't want to bail at the first failure,as the user might 
# then bypass the hooks without knowing about additional issues. 

for hook in $GIT_DIR/hooks/$hookname-*; do 
   test -x "$hook" || continue 
   echo "$data" | "$hook" 
   exitcodes+=($?) 
 done
