-f : 如果有多行表达式,且频繁修改,用文件存储这些命令表达式则显得尤为高效,而 -f 代表的就是命令文件; -i: in-place 就地修改并保存。如果不指定 sed 将修改后的结果输出到标准输出也就是屏幕上 主要是围绕着 script 做文章,指定的命令可以完成目标文本的转换, 而 options 则更多是一些可选的动作,比如直接...

sed 即 stream editor,一个简单而强大的文本解析转换工具,1973-1974年期间由贝尔实验室的 Lee E. McMahon 开发,能够完美的配合正则表达式使用。 处理文本时,当前处理的行会先存储在临时缓冲区中,称为模式空间(pattern space),操作完成后再把缓冲区的内容送往屏幕。接着处理下一行,直到文件末尾。文件内容并没有改变...
