Question

I have file names with prefix – “file” and random number suffix. for example:

file2344, file1244, file123, file12345, file0012

I want to create the files renamed with sequential number so that they can work well in arrays. for example:

file1, file2, file3, file4, file5

How can I achieve this ?

Answer 1

Something like that:

i=1
for f in file*; do
    mv "$f" file$i
    i=$((i+1))
done
