How to Use
Checking
The following command checks whether the given directory contains files with inconsistent indices (e.g. containts both foo004.jpg and foo004_01.jpg):
$ renum-files-exe --check source/Filenames must match \a+\d\d\d(\_\d\d)?\.\a+.
Normalization
The following command normalizes indices (i.e. eliminates all the gaps between indices):
$ renum-files-exe --normalize target/Unification
# the source directory, the contents of which have been added manually
$ ls source/
bar003.png
bar008_01.jpeg
bar008_02.jpeg
foo001.jpeg
foo004_01.png
foo004_02.png
foo042.jpg
# the target directory, where files are to be kept with normalized indices
$ ls target/
bar001.jpg
bar002_01.png
bar002_02.png
bar002_03.png
bar003.png
bar004.jpg
foo001_01.jpg
foo001_02.png
foo002.jpg
$ renum-files-exe --normalize source/ target/
# (some texts on stdout)
$ ls source/
$ ls target/
bar001.jpg
bar002_01.png
bar002_02.png
bar002_03.png
bar003.png
bar004.jpg
bar005.png # <= source/bar003.png
bar006_01.jpg # <= source/bar008_01.jpeg
bar006_02.jpg # <= source/bar008_02.jpeg
foo001_01.jpg
foo001_02.png
foo002.jpg
foo003.jpg # <= source/foo001.jpeg
foo004_01.png # <= source/foo004_01.png
foo004_02.png # <= source/foo004_02.png
foo005.jpg # <= source/foo042.jpgSumming up
The following command counts how many indices are used for each tag:
$ renum-files-exe --sum-up target/
