sed [OPTION] [expression] file

[OPTION]
  -n 屏蔽输出
  -i 替换模式
  -i.bak 替换前先备份文件
  -E 使用扩展正则表达式，语法更接近现代正则表达式（如 Perl、Python、JavaScript），代码更清晰易读（去掉了很多反斜杠），减少转义错误
  -e 使用表达式，可使用多个表达式

[expression]
  s/regular/replace/ 替换命令
  
  0,/regular/s//replace/ 仅替换从文件开头（第 0 行）首次匹配regular成功的内容，只用GNU版本的sed
  
  /regular/replace/g 匹配整行，默认只匹配一次
  /regular/replace/d 删除行
  /regular/replace/p 打印匹配的行

# 删除空行
sed -i '/^\s*$/d' merge1.log
sed -i '/^$/d' filename.txt  # `^$` 匹配空行

# 删除最后一行
sed -i '$d' filename.txt  # `$` 表示最后一行
# 删除连续行
sed -i '10,20d' filename.txt  # 删除第10到20行
# 删除不连续的行
sed -i '5d;10d;15d' filename.txt  # 删除第5、10、15行
# 删除包含特定文本的行
sed -i '/pattern/d' filename.txt  # 删除含"pattern"的行
# 删除不匹配的行（保留匹配行）
sed -i '/pattern/!d' filename.txt  # `!` 表示取反
