我是写bash脚本的新手,我有一个创建的npm包 https://www.npmjs.com/package/comgen
重击
days=3
hours=24
minutes=60
totalNumberOfCommits=3
lenghtOfTime=$((days*hours*minutes))
arrayOfCommits=$(shuf -i 1-$lenghtOfTime -n $totalNumberOfCommits | sort -r -n)
for index in $arrayOfCommits
do
randomMessage=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1)
git commit --allow-empty --date "$(date -d "-$index minutes")" -m "$randomMessage"
done
git push origin master
您可以这样运行它 npm run comgen 我希望它像这样运行:
npm run comgen -days "x number of days" -totalNumberOfCommits "x number of commits"
Package.json
"scripts": {
"comgen": "commit-generator.sh"
},
通过天数和提交的总次数将替换bash脚本中变量中的数字。

我不确定npm
的工作原理,但是根据我的经验,我猜想命令行参数会直接传递给被调用的可执行文件(二进制或脚本)。这意味着您的脚本实际上被称为
/path/to/comgen -days "x number of days" -totalNumberOfCommits "x number of commits"
现在,解析cmdline参数是纯Bash的东西。您评估一个选项并确定下一个值是什么:
days=3
hours=24
minutes=60
totalNumberOfCommits=3
while [ $# -ne 0 ]; do
case "$1" in
"-d"|"-days") days=$2; shift 2;;
"-tc"|"-totalNumberOfCommits") totalNumberOfCommits=$2; shift 2;;
# "-x"|"-xx"|"-xxx") : Process another option; shift 2;;
*) break;;
esac
done
lenghtOfTime=$((days*hours*minutes))
... rest of the code

试试这个
package.json
"scripts": {
"comgen": "commit-generator.sh"
},
commit-generator.sh
#!/bin/bash
echo $npm_config_days
echo $npm_config_hours
最后在终端
npm run comgen --days=foo --hours=bar
输出:
> commit-generator.sh
foo
bar
