This project contains the command line tools 'seqls', 'seqsum', 'seqcp', which are similar to 'ls', 'cp', 'shasum' but for sequences of files.
Here is an example:
>>> ls /tmp/sequences
>>> background.0001.jpg
>>> background.0002.jpg
>>> background.0003.jpg
>>> background.0004.jpg
with seqls:
>>> seqls /tmp/sequences
>>> background.%04d.jpg 1 4
Those tools are used a lot in the vfx and post production industries, where the sequences of files are very common. They are available for download and don't require any dependencies.
List sequences of files in directories
seqls [-RglmcsS] [-e exr,dpx,...] [-j 3] [-f nuke|rv|printf] [files ...] [directories ...]
Compute the hash value of all sequences of files in directories. It processes all the files with the SHA224 algorithm as if they were concatenated in a single block
seqsum [-Rj] [files ...] [directories ...]
Copy a subset of a sequence of files in a destination directory.
seqcp [-vc] /path/to/sequence.%05d.exr [first frame] [last frame] [target directory]
The binaries are available in the releases page. To install, just unzip, untar and copy the files in a executable path of your choice. If you need another platform, just email me or build the project from sources.
The code is written in Haskell and you will need to install 'stack' if you want to build your own version. (see: https://docs.haskellstack.org/en/stable/README/). Once stack is installed, just retrieve the source code:
git clone https://github.com/cpichard/filesequence
and run the following commands in the filesequence directory:
cd filesequence
stack build
stack install --local-bin-path BINARY_PATH
It will build and install the tools in BINARY_PATH
.
seqls -lg /path/to/directory
-rw-r--r-- 93.09K 210.29K 7.95M 1 50 /path/to/directory/checker_board_distotest.%04d.png
-rw-r--r-- 38.35K 133.74K 4.72M 1 50 /path/to/directory/checker_board_clean.%04d.png
There are 2 sequences in this folder. On the first sequence, the minimum size of a frame is 93.09K, the maximum 210.29K, the total size of the first sequence is 7.95M, the first frame is 1, last frame 50.
