find / -name alpha -exec chmod a+r {} (My space web page)
find / -name alpha -exec chmod a+r {} ; Following -exec, you should specify a complete UNIX command and put {} where the filename will be inserted. Add ; at the end of the command to complete the required syntax. In the previous example, chmod runs on every file named alpha so that everyone can read the file. find / -name core -exec rm -f {} ; This example finds all files on the system named core and executes the rm command to delete them. The - f option to rm is specified so that rm does not ask for confirmation if you don’t own the file and don’t have write permission to the file. This is a useful command for root to run periodically because, if a process aborts, it might leave a debugging file named core in the current directory. After a while, these core files, which are not small, can collectively consume an unreasonable amount of disk space. This find command restores that disk space by finding and deleting those core files. Note - If you have thousands of files to process, xargs (covered in the next section) is more efficient than - exec. For example, find / -name core -print | xargs rm -f This command also deletes all core files much more quickly and with less overhead than the -exec option, which calls rm once for each file.
