mass renaming

find (maxdepth, regex) + perl + xargs + mv

• do below without mv first to check io
• then execute mass rename with mv

find . -maxdepth 1 -type f
-regex ".\/.*something.*\.txt" | 
perl -pe 'print $_; s/.\/find/.\/replace/' | 
xargs -n2 
mv

find + exec mv

• more efficient, but can’t check io

find path_A -name '*AAA*' -exec mv -t path_B {} +
