I think you can achieve exactly the same without pipes with:
> find . -name whatever\* -type f -print -delete
... except this variation should be safe with filenames containing the '\n' character (which is perfectly legal on most UNIXes).
> find . -name whatever\* -type f -print -delete
... except this variation should be safe with filenames containing the '\n' character (which is perfectly legal on most UNIXes).
You can use find -print0 | perl -0ne 'print($_);' ... using a null instead of newlines.
You're correct that -delete is easier in this case, but the perl one liner is handy (as a starting point) if you're doing something conditional, or changing file extensions in bulk, etc.
Or you can also do it all in Perl:
perl -E 'while (<whatever*>) { say; unlink }'
Hello!
perl -MFile::Find -e 'find sub{if(-f&&/^whatever/){say$File::Find::name;unlink}},"."'
perl -E 'sub x{say;for(<$_/*>){&x;unlink}};x for@ARGV' *
perl -E 'push@ARGV,<$_/*>for@ARGV;say,unlink for@ARGV' *Also, I think yours would go into an infinite spin if it met a symlink loop (say, "ln -s . foo") - File::Find is hardened against that kinda shenanigans.
perl -E 'for(@ARGV){say,unlink for<$_/whatever*>;push@ARGV,($_)x(-d^-l)for<$_/*>}' .
