  • How to truncate all logfiles?

    4 answers




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

          • How to clear these files using the command line? I know how to find. To clear a single file I would use > old_name.log But I want to clear multiple files instead of typing each one of their names.

          • @Shameless Oh, I thought "clear" meant "delete". Usually I've heard emptying a file called "erasing" or maybe "zeroing" or "wiping". I'll revise the answer to do that.

            @wjandrea this won't work right. Your rm code won't delete log files named *.log.01, *.log.02, etc. Your tee code won't get ANY log files with any names like *.log.1, *.log.01, etc. And, you don't want to touch any *.log file, as it's probably an open active file.

          Note that OP apparently wants to truncate files. In such case, the desired command is



          find /path/to/dir -regextype sed -regex ".*.log[1-9]*" -exec truncate -s 0 {} ;


          Alternatively, in bash



          shopt -s globstar
          truncate -s 0 **/*.log[1-9]




          If you want to clear out any file that has .log in the name



          find /path/to/dir -name "*.log*"


          If you target .log[digit] specifically, use



          find /path/to/dir -regextype sed -regex ".*.log[1-9]*"


          Once you verify either of these two commands find the files you want, append -delete to the command for actual removal

            @Shameless Please read the last sentence in my answer. find with -delete option does exactly what you ask. Full command is find /path/to/dir -regextype sed -regex ".*.log[1-9]*" -delete . It's common practice to first list files, then delete them to avoid unintended errors.

          Quick and dirty... assuming that you have permissions for these log files and directory itself... and you wish to delete the .log* files...




          1. in a Files window, open the directory where the log files are located

          2. search for .log files


          3. Select All, control-click any files to exclude (like the active and open *.log)

          4. then Move to Trash


          Note: if you wish to "clear" the .log file, close the application that makes the current .log file, then delete the current .log file with Move to Trash, and then right-click in the folder, select New Document, then Blank Document, and Rename... using the correct .log filename.

          • How to clear these files using the command line? I know how to find. To clear a single file I would use > old_name.log But I want to clear multiple files instead of typing each one of their names.

            @Shameless Please read the last sentence in my answer. find with -delete option does exactly what you ask. Full command is find /path/to/dir -regextype sed -regex ".*.log[1-9]*" -delete . It's common practice to first list files, then delete them to avoid unintended errors.

            @Shameless If by clear you mean "keep filename, but delete contents", then you want find /path/to/dir -regextype sed -regex ".*.log[1-9]*" -exec truncate -s 0 {} ;

          Note that OP apparently wants to truncate files. In such case, the desired command is



          find /path/to/dir -regextype sed -regex ".*.log[1-9]*" -exec truncate -s 0 {} ;


          Alternatively, in bash



          shopt -s globstar
          truncate -s 0 **/*.log[1-9]




          If you want to clear out any file that has .log in the name



          find /path/to/dir -name "*.log*"


          If you target .log[digit] specifically, use

          Quick and dirty... assuming that you have permissions for these log files and directory itself... and you wish to delete the .log* files...




          1. in a Files window, open the directory where the log files are located

          2. search for .log files


          3. Select All, control-click any files to exclude (like the active and open *.log)

          4. then Move to Trash


          Note: if you wish to "clear" the .log file, close the application that makes the current .log file, then delete the current .log file with Move to Trash, and then right-click in the folder, select New Document, then Blank Document, and Rename... using the correct .log filename.
