linux:files:file:delete:line
Delete a single line from a given file
$ sed -i '${line_number}d' ${filename}
try on your machine
This command uses the sed (stream editor) tool to delete a specific line in a file.
- '${line_number}d' - This is the command that tells sed to delete a specific line. The curly braces indicate that the line number is a variable. So, replace '${line_number}' with the actual line number you want to delete.
- ${filename} - This is the name of the file in which you want to delete the line. Replace '${filename}' with the actual name of the file you want to work with.
- -i - This flag tells sed to edit the file in place (overwrite the original file). Without this flag, sed would only output the modified file to the console.
