Linux Command Tips

1.delete all executable files under certain directory

find /directory -type f -executable -delete

or

find /directory  -type f -executable -exec rm -f {} \;

Above command will delete the executable files in sub-directory.

To specifically delete all executable files in your home directory (not in sub-directories) and ask you whether you want to delete each file you can do something like

find ~ -type f -executable -maxdepth 0 -exec rm -i {} \;
