Eu segui passo a passo -criar-um-pendrive-usb-inicializável meu pendrive

Device        Start      End  Sectors  Size Type
/dev/sda1        64 12105119 12105056  5,8G Microsoft basic data

/dev/sda4  12115968 61437951 49321984 23,5G Linux filesystem

Quando reinicio o laptop, só aparece a linha que

error file `/boot/` not found

Eu continuo e termino algo, mas a primeira reinicialização retorna ao initramfs.

insira a descrição da imagem aqui Por quê? É um problema de BIOS (meu laptop é Hp EliteBook)?

Se eu tentar

sudo umount -f /dev/sda
umount: /dev/sda: not mounted.

mas Ventoy falha

sudo bash Ventoy2Disk.sh -i /dev/sda

O Myscript será executado todos os dias e excluirá os arquivos antigos. Crie o arquivo para onde desejo redirecionar a saída

echo myproj-"date+ %Y-%m-%d"

Agora do cli

jf rt del (some files) >como especificar meu arquivo aqui

A cada dia será diferente, por causa do registro de data e hora.

Como adicionar isso?

Eu tenho linha

* {@jira: PIVOT-9968} Provide a way to pass an `IMemoryCollector` to `IInternalMemoryMonitored#getMemoryStatistics(memoryCollector)` in order to prevent the count of duplicated blocks.

Eu queria escapar apenas do primeiro que contém o número do tíquete(?). Escreva um script para adicionar barra invertida para meu problema anterior

* /{@jira: PIVOT-9968/} Provide a way to pass an `IMemoryCollector` to `IInternalMemoryMonitored#getMemoryStatistics(memoryCollector)` in order to prevent the count of duplicated blocks.

tentei

mawk '/^\* {@jira: PIVOT/ { gsub(/[{} ]/,"\\\\&") } 1' changelog.md > tmp && mv tmp changelog.md

e consegui

*\ \{@jira:\ PIVOT-8019\}\ Pivot:\ Added\ `MaxAppendOnlyFunction`\ and\ \ `MinAppendOnlyFunction`\ aggregation\ functions\ that\ do\ not\ support\ disaggregation\ but\ can\ be\ used\ within\ an\ aggregate\ provider.

o que devo mudar? gsub?

Eu já postei adicionar caractere de escape com bash . Preciso de um script para isso para cada linha em um arquivo que começa com {@codeBlock

então

{@codeBlock: TEstBigquerry.buildPicks}

deveria parecer

\{@codeBlock:\ TEstBigquerry.buildPicks\}

Meu roteiro

#!/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

A saída do terminal está ok, mas o arquivo continua o mesmo. Por quê?

Estou tendo problemas com o código legado da empresa. Dockerfile

RUN rm -Rf /opt/app/src/api

COPY src/ /opt/app/src/
COPY config.json /opt/app/config.json

serve para que RUN rm -Rf? Por que o cara que escreveu o Dockerfile o adicionou? Como ele será mapeado no contêiner?

Isso deveria ser trivial, mas parece que não é. Formatei meu comp e instalei o conda (estou acostumado com esta ferramenta de pacote)

pip install awscli --upgrade --user
Requirement already up-to-date: awscli in ./.local/lib/python3.7/site-packages (1.16.313)

Mas agora estou com problema

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

eu tentei

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

Atualizei e atualizei minha distro para não ver nenhum problema desse lado. Como consertar isto?

Eu estava instalando o Hadoop no meu Ubuntu.

ll: command not found

Minha linha de edição bashrc

echo 'export HADOOP_HOME=/opt/hadoop-3.2.0;export PATH=$HADOOP_HOME/bin:$PATH' > ~/.bashrc

o arquivo ~/.bashrc tem apenas uma linha

export HADOOP_HOME=/opt/hadoop-3.2.0

Todos os scripts anteriores foram excluídos.

Tentei novamente abrir 22

sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT

mas ainda não vejo 22 com netstat

netstat -tpln | grep 22

Como resolver este problema?

RESOLVIDO Era um problema de sshd. Limpei e instalei o servidor OpenSSH.

Eu queria verificar o tamanho do backup do meu sistema de arquivos

ls -lia backup.tgz 
17 -rw-r--r-- 1 root root 84972633333 мај 28 10:05 backup.tgz

Com tamanho de bloco M

 ls -l --block-size=M backup.tgz 
-rw-r--r-- 1 root root 81037M мај 28 10:05 backup.tgz

Finalmente com tamanho de bloco G

ls -l --block-size=G backup.tgz 
-rw-r--r-- 1 root root 80G мај 28 10:05 backup.tgz

Alguém poderia explicar uma diferença tão grande?
