Perl glob one liner

Question

Im working in a perl one liner to invert the contents of my file contents or perform operations, I was able to generate the script and one liner, but this one liner only works by entering file by file.

perl -i -ne '$a=reverse $_;print "$a\n"' <filename>

I want to change my one liner to get input from a range of files but when i do:

perl -i -ne '$a=reverse $_;print "$a\n"' | ls -al

I just get screen output of ls -al Not sure how to proceed.

Thanks

Answer 1

你可以使用xargs（1）：

ls | xargs perl -i -ne '$a=reverse $_;print "$a\n"' 

Answer 2

perl -nle '$c=reverse;print $c' * .*
