Delete executables and object (.o) files

Following two commands can delete all ELF executables and ELF object (.o) files.

find ./ -executable -type f|xargs -I{} file {} | grep ELF|cut -d ':' -f 1|xargs -I{} rm {}   

find ./ -name "*.o" -type f|xargs -I{} file {} | grep ELF|cut -d ':' -f 1|xargs -I{} rm {}

Some executables may not be found because its "x" bit is not set. Use following command to find them

find ./ -type f|xargs -I{} file {} | grep ELF|cut -d ':' -f 1|xargs -I{} rm {}

Note:
    -executable is not supported in old version of find.
