提交时是否有限制文件大小的选项？
例如：文件大小超过 500K 将产生警告。文件大小超过 10M 将停止提交。
我完全意识到这个问题，从技术上讲，这使得这个问题重复，但答案只提供了一个解决方案在推送时，这对于我的要求来说已经太晚了。
此预提交挂钩将执行文件大小检查：
.git/hooks/预提交
#!/bin/sh
hard_limit=$(git config hooks.filesizehardlimit)
soft_limit=$(git config hooks.filesizesoftlimit)
: ${hard_limit:=10000000}
: ${soft_limit:=500000}
list_new_or_modified_files()
{
git diff --staged --name-status|sed -e '/^D/ d; /^D/! s/.\s\+//'
}
unmunge()
{
local result="${1#\"}"
result="${result%\"}"
env echo -e "$result"
}
check_file_size()
{
n=0
while read -r munged_filename
do
f="$(unmunge "$munged_filename")"
h=$(git ls-files -s "$f"|cut -d' ' -f 2)
s=$(git cat-file -s "$h")
if [ "$s" -gt $hard_limit ]
then
env echo -E 1>&2 "ERROR: hard size limit ($hard_limit) exceeded: $munged_filename ($s)"
n=$((n+1))
elif [ "$s" -gt $soft_limit ]
then
env echo -E 1>&2 "WARNING: soft size limit ($soft_limit) exceeded: $munged_filename ($s)"
fi
done
[ $n -eq 0 ]
}
list_new_or_modified_files | check_file_size
以上脚本必须保存为
.git/hooks/pre-commitchmod +x .git/hooks/pre-commit默认的软（警告）和硬（错误）大小限制设置为 500,000 和 10,000,000 字节，但可以分别通过
hooks.filesizesoftlimithooks.filesizehardlimit$ git config hooks.filesizesoftlimit 100000
$ git config hooks.filesizehardlimit 4000000
@Leon 脚本的较短的、特定于 bash 的版本，它以人类可读的格式打印文件大小。它需要一个更新的 git 来实现
--diff-filter=d#!/bin/bash
hard_limit=$(git config hooks.filesizehardlimit)
soft_limit=$(git config hooks.filesizesoftlimit)
: ${hard_limit:=10000000}
: ${soft_limit:=1000000}
status=0
bytesToHuman() {
b=${1:-0}; d=''; s=0; S=({,K,M,G,T,P,E,Z,Y}B)
while ((b > 1000)); do
d="$(printf ".%01d" $((b % 1000 * 10 / 1000)))"
b=$((b / 1000))
let s++
done
echo "$b$d${S[$s]}"
}
# Iterate over the zero-delimited list of staged files.
while IFS= read -r -d '' file ; do
hash=$(git ls-files -s "$file" | cut -d ' ' -f 2)
size=$(git cat-file -s "$hash")
if (( $size > $hard_limit )); then
echo "Error: Cannot commit '$file' because it is $(bytesToHuman $size), which exceeds the hard size limit of $(bytesToHuman $hard_limit)."
status=1
elif (( $size > $soft_limit )); then
echo "Warning: '$file' is $(bytesToHuman $size), which exceeds the soft size limit of $(bytesToHuman $soft_limit). Please double check that you intended to commit this file."
fi
done < <(git diff -z --staged --name-only --diff-filter=d)
exit $status
与其他答案一样，必须使用执行权限将其保存为
.git/hooks/pre-commit输出示例：
Error: Cannot commit 'foo' because it is 117.9MB, which exceeds the hard size limit of 10.0MB.
您需要实现您已经在 pre-commit
hook中查找的 eis 脚本。
从文档中，我们了解到预提交钩子
不带任何参数，并且 在获取建议的提交日志消息并进行提交之前被调用。从此脚本中以非零状态退出会导致 git commit 命令在创建提交之前中止。
基本上，调用钩子来检查是否允许用户提交他的更改。
#!/bin/bash
# File size limit is meant to be configured through 'hooks.filesizelimit' setting
filesizelimit=$(git config hooks.filesizelimit)
# If we haven't configured a file size limit, use default value of about 10M
if [ -z "$filesizelimit" ]; then
filesizelimit=10000000
fi
# You specify a warning limit
filesizewarning=500000
# With this command, we can find information about the file coming in that has biggest size
# We also normalize the line for excess whitespace
biggest_checkin_normalized=$(git ls-tree --full-tree -r -l HEAD | sort -k 4 -n -r | head -1 | sed 's/^ *//;s/ *$//;s/\s\{1,\}/ /g' )
# Based on that, we can find what we are interested about
filesize=`echo $biggest_checkin_normalized | cut -d ' ' -f4,4`
# Actual comparison
# To cancel a push, we exit with status code 1
# It is also a good idea to print out some info about the cause of rejection
if [ $filesize -gt $filesizelimit ]; then
# To be more user-friendly, we also look up the name of the offending file
filename=`echo $biggest_checkin_normalized | cut -d ' ' -f5,5`
echo "Error: Too large push attempted." >&2
echo >&2
echo "File size limit is $filesizelimit, and you tried to push file named $filename of size $filesize." >&2
echo "Contact configuration team if you really need to do this." >&2
exit 1
elif [ $filesize -gt $filesizewarning ]; then
echo "WARNING ! A file size is bigger that $filesizewarning"
fi
exit 0
有一个通用的预提交钩子。您可以编写脚本来检查文件大小，然后接受或拒绝提交。然而，Git 使用户能够绕过检查）从命令行输入“git help hooks”以获取更多信息。这是预提交挂钩的相关信息。
预提交
该钩子由 git commit 调用，可以使用 --no-verify 选项绕过。它不带任何参数，并且在获取建议的提交日志消息并进行提交之前调用。从此脚本中以非零状态退出会导致 git 提交中止。
只是想评论@Leon 提供的解决方案非常棒。我遇到了一个小问题，如果开始尝试跟踪空目录，它就会中止。所以我必须补充一下
[ -d "$f" ] && continue
在
ls-files我更愿意发表评论，因为这不是答案，但我没有声誉点。
注意：我知道 git 'ignores' 目录，但显然不是在预提交挂钩运行之前。
我进一步修改了@connor-mckay & @vtwaldo21。它在空文件上给我带来了一些错误
