Which brings up this: rm *.log will wipe out all files ending in .log in one stroke. When using wildcards with rm it is best to use rm -i, i stands for interactive and prompts you y or n to delete a file. So, if you were to type rm -i *.log then you will be prompted for each file that matches *.log. So, if one of the logs was named superimportant_DONOTDELETE.log then rm -i *.log would give you the opportunity to keep that file.
