If i don't understand any script which have lot of conditions and scenarios, I prefer to test script part by part. Divide script into multiple pieces so it can be understandable.. Run script part by part....Smilie

the directories looks like this :

Code:
aabbccdde -- ffgghh iijjkkll5566778

to
Code:
5566778 aabbccdde -- ffgghh iijjkkll

sometimes there's only one string
Code:
aab55ccddeeffgghh6677

to
Code:
6677 aab55ccddeeffgghh

No my script doesn't work for these directories you have mentioned since its different conditions all together....But you can use the logic in my script as a workaround ..let me know if any help required in the same..

Try shell only:
Code:
for file in *.ext
do
  first=${file%% -- *}
  secondext=${file##* -- }
  second=${secondext%.*}
  ext=${file##*.}
  middle=${file#$first}
  middle=${middle%$secondext}
  mv "$file" "$second$middle$first.$ext"
done

that's what i want to ask you after the precision, do you want to help to understand a little bit of your script

what are the meaning of
Code:
 
$p
$1
$F[0]
$F[1]

thanks !
Your requirement seems to have changed. There is no separator in the second example ?
And the first example does not switch left and right side...

for inversing strings delimited by "--" in filenames, this script works perfectly !

that put the last string to the beginning & vice versa

---------- Post updated at 07:12 PM ---------- Previous update was at 06:15 PM ----------


thanks for your perspicacity ! you're right i've found a solution when there are only one string
i add " -- " at the end to fits the script

so don't take that example (aab55ccddeeffgghh6677)

i only need want to know if the script works for the directories

i've checked the mv command page and adding "-t" option perhaps may help

but i don't quite sure and i don't know if it fit in the script

Code:
ls *ext | perl -F"--" -alne '{if($#F==1){
if($F[1]=~/(\d+).ext/){ $p=$1;$F[0]=~s/^/$p /g;$F[1]=~s/$p//;print "mv \"$_\" \"".join(" -- ",@F)."\"" ;}
else { ($F[0],$F[1])=($F[1],$F[0]);$F[0]=~s/(.ext|^ *)//;$F[1]=~s/ *$/.ext/;print "mv \"$_\" \"".join(" -- ",@F)."\"" ;}
}else{ ($F[0],$F[2])=($F[2],$F[0]);$F[0]=~s/(.ext|^ *)//;$F[2]=~s/ *$/.ext/;;print "mv \"$_\" \"".join(" -- ",@F)."\"" ;}
}' | sh
