Ok.
1>First store all the necessary directory names into one file like "temp" and execute as usual to check if this is satisfying your conditions
Code:
perl -lne '{$Tget=$_;$_=~s/(.*?)(\d+)$/$2 $1/g;print "mv \"$Tget\" \"$_\""}' temp
mv "aabbccdde -- ffgghh iijjkkll5566778" "5566778 aabbccdde -- ffgghh iijjkkll"
mv "aab55ccddeeffgghh6677" "6677 aab55ccddeeffgghh"

2>Execute the same now
Code:
perl -lne '{$Tget=$_;$_=~s/(.*?)(\d+)$/$2 $1/g;print "mv \"$Tget\" \"$_\""}' temp | sh

And one more thing...
normal mv works for directories also...you don't have to use any option unless some peculiar case which i may not have come across...

-t option is invalid usage here. This is what man page says :
Code:
       -t, --target-directory=DIRECTORY
              move all SOURCE arguments into DIRECTORY

which means moving(not renaming) multiple files into a directory.

Hi msabhi, perl does have a file rename operator, if you'd forgotten about it.

Right elixir...new to PERL workarounds for files..somehow forgot its usageSmilie
Below code would be more efficient...Smilie
Code:
perl -lne '{$Tget=$_;$_=~s/(.*?)(\d+)$/$2 $1/g;rename "$Tget", "$_"}' temp
