Explanation of a bash command

Hi /prog/,

Can you explain this command for me
for f in *.lib; do mv $f lib${f%%lib}a; done

First of all, this translation is horrible! “Sixteen judges from a jury eat liver from a hanged man” would be a bit better. Also, this is just a tongue twister, so it's not intended to make sense, only being gramatically correct.

My post was only to note that month names are spelled in Catalan. OP may be from Barcelona.

Now try to translate “Un plat pla blau clar ple de pebre negre està”.
