In Linux, you can use the following command to delete specific lines of data from a file.<\/p>\n

    \n
  1. sed is a stream editor commonly used for parsing and transforming text.<\/li>\n<\/ol>\n
    sed -i '<\u884c\u53f7>d' \u6587\u4ef6\u540d\r\n<\/code><\/pre>\n
    In this case,  is the number of the line to be deleted, and the file name is the name of the file to operate on. For example, to delete the data in the 5th line of the file file.txt, you can use the following command:<\/p>\n
    sed -i '5d' file.txt\r\n<\/code><\/pre>\n
      \n
    1. search<\/li>\n<\/ol>\n
      grep -v '<\u884c\u5185\u5bb9>' \u6587\u4ef6\u540d > \u4e34\u65f6\u6587\u4ef6\u540d && mv \u4e34\u65f6\u6587\u4ef6\u540d \u6587\u4ef6\u540d\r\n<\/code><\/pre>\n
      In this command, <\u884c\u5185\u5bb9> represents the content of the line to be deleted, file name is the name of the file to be operated on, and temporary file name is a temporary file name. For example, to delete a line in the file file.txt that contains the string “hello”, you can use the following command:<\/p>\n
      grep -v 'hello' file.txt > temp.txt && mv temp.txt file.txt\r\n<\/code><\/pre>\n
      This command will create a temporary file called temp.txt, write the lines that do not contain “hello” into it, and then rename the temporary file as the original file name file.txt.<\/p>\n
      Please remember to back up your files before using these commands to delete data, in order to avoid accidental deletion or modification.<\/p>\n","protected":false},"excerpt":{"rendered":"
