我想在两个模式之间添加一些大代码: FILE1.TXT This is text to be inserted into the File. infile.txt Some Text here First Second Some Text here 我想在First和Second之间添加File1.txt内容: 期望的输出: Some Text here First This is text to be inserted into the File. Second Some Text here 我可以使用sed命令使用两种模式进行搜索,但我不知道如何在它们之间添加内容. sed '/First/,/Second/!d' infile 解决方法由于/ r代表读取文件,请使用:sed '/First/r file1.txt' infile.txt 你可以在这里找到一些信息:Reading in a file with the ‘r’ command. 为就地版添加-i(即sed -i’/ First / r file1.txt’infile.txt). 要执行此操作,无论字符是什么情况,请使用Use sed with ignore case while adding text before some pattern中建议的I标记: sed 's/first/last/Ig' file 如评论中所示,上述解决方案仅仅是在模式之后打印给定的字符串,而不考虑第二模式. 要这样做,我会去拿一个标志的awk: awk -v data="$(<patt_file)" '/First/ {f=1} /Second/ && f {print data; f=0}1' file
鉴于这些文件: $cat patt_file This is text to be inserted $cat file Some Text here First First Second Some Text here First Bar 让我们运行命令: $awk -v data="$(<patt_file)" '/First/ {f=1} /Second/ && f {print data; f=0}1' file
Some Text here
First # <--- no line appended here
First
This is text to be inserted # <--- line appended here
Second
Some Text here
First # <--- no line appended here
