Ubuntu – How to clear all files in a folder ending with `.log`?

18.04deletefiles

I have log files in a folder. These files after some size are creating a new file old_name.log1 and writing to it.

Now there are many files and I can't clear them one by one. I want to delete old_name.log1, old_name.log2 etc and clear old_name.log.

The file_name can be anything. But the file ends with .log and it's extended files ends with .log1, .log2, etc. How to do it?

  • To delete .log1, .log2, etc. files:

    rm *.log[1-9]*
    
    • rm - Delete files
    • *.log[1-9]* - All files in the current directory that contain .log followed by a digit 1-9 then anything else

    To test the command before running it, replace the rm with echo. It will print the matching files.

    To truncate .log files:

    echo -n | tee *.log
    
    • echo -n - Print nothing
    • tee *.log - Write from stdin to all .log files in the current directory
