当我重新启动笔记本电脑时，只出现
error file `/boot/` not found
我继续并完成一些事情但首先重启会回到 initramfs。
为什么？这是 BIOS 问题吗（我的笔记本电脑是 Hp EliteBook）？
如果我尝试
sudo umount -f /dev/sda
umount: /dev/sda: not mounted.
但 Ventoy 失败了
sudo bash Ventoy2Disk.sh -i /dev/sda

我应该尝试什么？
Myscript 将每天运行，并删除旧文件。创建我想要重定向输出的文件
echo myproj-"date+ %Y-%m-%d"
现在从 CLI
jf rt del (some files) >如何在这里指定我的文件
每天都会有所不同，因为有时间戳。
如何添加？
我有线
* {@jira: PIVOT-9968} Provide a way to pass an `IMemoryCollector` to `IInternalMemoryMonitored#getMemoryStatistics(memoryCollector)` in order to prevent the count of duplicated blocks.
我只想转义第一个包含票号的字符。 编写脚本以添加反斜杠来 解决我之前的问题
* /{@jira: PIVOT-9968/} Provide a way to pass an `IMemoryCollector` to `IInternalMemoryMonitored#getMemoryStatistics(memoryCollector)` in order to prevent the count of duplicated blocks.
我试过
mawk '/^\* {@jira: PIVOT/ { gsub(/[{} ]/,"\\\\&") } 1' changelog.md > tmp && mv tmp changelog.md
并得到
*\ \{@jira:\ PIVOT-8019\}\ Pivot:\ Added\ `MaxAppendOnlyFunction`\ and\ \ `MinAppendOnlyFunction`\ aggregation\ functions\ that\ do\ not\ support\ disaggregation\ but\ can\ be\ used\ within\ an\ aggregate\ provider.
我应该改变什么？gsub？
我已经发布了使用 bash 添加转义字符。我需要为以 {@codeBlock 开头的文件中的每一行编写此脚本
所以
{@codeBlock: TEstBigquerry.buildPicks}
应该看起来像
\{@codeBlock:\ TEstBigquerry.buildPicks\}
我的脚本
#!/bin/bash
file=clfields.mdx
while read -r line; do
if [[ "${line::11}" == '{@codeBlock' ]]; then
printf '%q\n' "$line"
else
echo "$line"
fi
done < clfields.mdx
终端输出正常，但文件保持不变。为什么？
我想要这个
{@codeBlock: TEstBigquerry.buildPicks}
成为
\{@codeBlock: TEstBigquerry.buildPicks/}
我试过
sed -i '/{@/\{@' joana.txt
得到
sed：-e 表达式 #1，字符 5：未知命令：''
如何添加两次转义字符串？

让我们检查
nvm install v20.0.0
v20.0.0 is already installed.
Now using node v20.0.0 (npm v9.6.4)
和
which npm
/home/miki/.nvm/versions/node/v20.0.0/bin/npm
为什么npm好像没有安装？我在乌布努图 22.04。
我在使用公司遗留代码时遇到问题。文件

有什么RUN rm -Rf用？为什么写Dockerfile的人要加上呢？它将如何映射到容器中？

如何修复容器内的权限？
我应该如何更改密码行？
这应该是微不足道的，但似乎并非如此。我格式化了我的comp并安装了conda（我习惯了这个打包工具）
pip install awscli --upgrade --user
Requirement already up-to-date: awscli in ./.local/lib/python3.7/site-packages (1.16.313)
但现在我有问题
aws --version
Command 'aws' not found, but can be installed with:
sudo snap install aws-cli # version 1.16.266, or
sudo apt install awscli
我试过了
sudo apt install awscli
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package awscli is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'awscli' has no installation candidate
我更新并升级了我的发行版，所以我看不到任何问题。如何解决这个问题？
快速安装

我的目标是 miki 是 hadoop-3.2.0 中所有文件的所有者。我想我应该使用chmod？命令应该是什么样子？
我正在我的 Ubuntu 上安装 Hadoop。
这是我现在的路径

如果我尝试ll
miki@miki:~$ ll
ll: command not found
我的 bashrc 编辑行
echo 'export HADOOP_HOME=/opt/hadoop-3.2.0;export PATH=$HADOOP_HOME/bin:$PATH' > ~/.bashrc
~/.bashrc 文件只有一行
export HADOOP_HOME=/opt/hadoop-3.2.0
所有以前的脚本都被删除了。

我想检查我的文件系统备份大小
ls -lia backup.tgz
17 -rw-r--r-- 1 root root 84972633333 мај 28 10:05 backup.tgz
块大小为 M
ls -l --block-size=M backup.tgz
-rw-r--r-- 1 root root 81037M мај 28 10:05 backup.tgz
最后使用块大小 G
ls -l --block-size=G backup.tgz
-rw-r--r-- 1 root root 80G мај 28 10:05 backup.tgz
有人可以解释如此巨大的差异吗？
