I have a folder with several files :

1-1.csv
1-2.csv
2-1.csv

And I want to rename them this way :

1-1-hist.csv
1-2-hist.csv
2-1-hist.csv

Following this post I tried the following :

for file in *.csv
do
  mv "$file" "${file/.csv/-hist.csv}"
done

But file names don't change and my terminal says :

mv: '1-1.csv' and '1-1.csv' are the same file
mv: '1-2.csv' and '1-2.csv' are the same file
mv: '2-1.csv' and '2-1.csv' are the same file

What am I doing wrong ?

EDIT :

rename 's/.csv/-hist.csv/' *.csv

did the job. Even if I don't know what did not work in the first attempt...

What are the underscores meant to do in the substitution? It seems like the shell is trying to match them, not finding them and therefore, not doing the substitution. – D Hydar Jul 23 '16 at 19:25

Remove the underscores. – Cyrus Jul 23 '16 at 19:28
I tried without the underscores but it is still the same...? for file in * do mv "$file" "${file/.csv/-hist.csv}" done – Vincent Jul 23 '16 at 19:48
The command, as it is now in the question, ought to work in `bash`. – Kusalananda Jul 24 '16 at 12:55
