CATCLI
The command line catalog tool for your offline data
Did you ever wanted to find back that specific file that should be on one of your backup DVDs or one of your external hard drives? You usually go through all of them hoping to find the right one on the first try? Catcli indexes external media in a catalog file and allows to quickly find specific files or even navigate in the catalog of indexed files while these are not connected to your host.
Features:
- Index any directories in a catalog
- Ability to search for files by name in the catalog
- Ability to navigate through indexed data à la
ls - Support for fuse to mount the indexed data as a virtual filesystem
- Handle archive files (zip, tar, ...) and index their content
- Save catalog to json for easy versioning with git
- Command line interface FTW
- Store files and directories sizes
- Store md5 hash of files
- Ability to update the catalog
- Support for
fzffor finding files - Tag your different storages with additional information
- Export catalog to CSV
Quick start:
# install catcli with pip
pip3 install catcli --user
# index a directory in the catalog
catcli index --meta='some description' log /var/log
# display the content
catcli ls -r
# navigate
catcli ls log
# find files/directories named '*log*'
catcli find log
see usage for specific info
Why catcli?
Catcli gives the ability to navigate, explore and find your files that are stored on external media (DVDs, hard drives, USB sticks, etc) when those are not connected. Catcli can just as easily index any arbitrary directories.
See the examples for an overview of the available features.

Installation
Install from Pypi
$ pip3 install catcli --user
Or from github directly
$ cd /tmp; git clone https://github.com/deadc0de6/catcli && cd catcli
$ sudo python3 setup.py install
$ catcli --help
To work with catcli without installing it, you can do the following
$ cd /tmp; git clone https://github.com/deadc0de6/catcli && cd catcli
$ pip3 install -r requirements.txt --user
$ python3 -m catcli.catcli --help
or install it in a virtualenv
$ cd /tmp; git clone https://github.com/deadc0de6/catcli && cd catcli
$ virtualenv -p python3 env
$ source env/bin/activate
$ python setup.py install
$ catcli --help
Catcli is also available on aur: https://aur.archlinux.org/packages/catcli-git/
Usage
Each indexed directory is stored in the catalog. Multiple directories can be indexed and they are all available through the command line interface of catcli.
Five different types of entry are present in a catalog:
- top node: this is the root of the hierarchy
- storage node: this represents an indexed storage (a DVD, an external hard drive, an USB drive, some arbitrary directory, etc).
- dir node: this is a directory
- file node: this is a file
- archive node: this is a file contained in an archive (tar, zip, etc)
Index data
Let's say the DVD or external hard drive that needs to be indexed
is mounted on /media/mnt. The following command
will index the entire directory /media/mnt
and store that in your catalog under the name <short-name>.
$ catcli index --meta=<some-description> <short-name> /media/mnt
If not specified otherwise (with the switch --catalog), the catalog is saved in the current
directory under catcli.catalog.
The --meta switch allows to add any additional information to store along in
the catalog like for example the blue disk in my office.
Catcli will calculate and store the total size of each node (directories, storages, etc)
unless the -n --no-subsize switch is used.
Using the -a --archive switch allows to also index archive files as explained
below.
Index archive files
Catcli is able to index and explore the content of archive files. Following archive formats are supported: tar, tar.gz, tar.xz, lzma, tar.bz2, zip. Catcli is also able to find files within indexed archive files.
See the archive example for more.
Walk indexed files with ls
A catalog can be walked using the command ls as if the media
is mounted (File/directories separator is /).
$ catcli ls tmp/a/b/c
Resulting files can be sorted by size using -S --sortsize.
See the examples for more.
Find files
Files and directories can be found based on their names
using the find command.
Find support two formats that allow to use fzf for
searching:
--format=fzf-native: display the result in native format--format=fzf-csv: display the result in csv
See the examples for more.
Mount catalog
The catalog can be mounted with fuse and navigate like any filesystem.
$ mkdir /tmp/mnt
$ catcli index -c github .github
$ catcli mount /tmp/mnt
$ ls -laR /tmp/mnt
drwxrwxrwx - user 8 Mar 22:08 github
mnt/github:
.rwxrwxrwx 17 user 19 Oct 2022 FUNDING.yml
drwxrwxrwx - user 2 Mar 10:15 workflows
mnt/github/workflows:
.rwxrwxrwx 691 user 19 Oct 2022 pypi-release.yml
.rwxrwxrwx 635 user 8 Mar 21:08 testing.yml
Display entire hierarchy
The entire catalog can be shown using the ls -r command.
Resulting files can be sorted by size using the -S --sortsize switch.
See the examples for more.
Catalog graph
The catalog can be exported in a dot file that can be used to generate a graph of the indexed files.
$ catcli graph
dot file created under "/tmp/catcli.dot"
create graph with "dot /tmp/catcli.dot -T png -o /tmp/tree.png" (you need graphviz)
$ dot /tmp/catcli.dot -T png -o /tmp/tree.png
Edit storage
Storage entry can be edited with following catcli commands:
rename- rename the storageedit- edit storage metadata
Update catalog
The catalog can be updated with the update command.
Updates are based on the access time of each of the files and on the
hash checksum if present (catalog was indexed with -c --hash and
update is called with the switch -c --hash).
CSV format
Results can be printed to CSV using --format=csv.
Fields are separated by a comma (,) and are quoted with double quotes (").
Each line contains the following fields:
- name: the entry name
- type: the entry type (file, directory, storage, etc)
- path: the entry path
- size: the entry size
- indexed_at: when this entry was indexed
- maccess: the entry modification date/time
- md5: the entry checksum (if any)
- nbfiles: the number of children (empty for not storage or directory nodes)
- free_space: free space (empty for not storage nodes)
- total_space: total space (empty for not storage nodes)
- meta: meta information (empty for not storage nodes)
Examples
Simple example
Let's first create some files and directories:
$ mkdir -p /tmp/test/{a,b,c}
$ echo 'something in files in a' > /tmp/test/a/{1,2,3}
$ echo 'something else in files in b' > /tmp/test/b/{4,5,6}
$ echo 'some bytes' > /tmp/test/c/{7,8,9}
$ tree /tmp/test
/tmp/test
├── a
│ ├── 1
│ ├── 2
│ └── 3
├── b
│ ├── 4
│ ├── 5
│ └── 6
└── c
├── 7
├── 8
└── 9
3 directories, 9 files
First this directory is indexed with catcli as if it was some kind of
external storage:
$ catcli index --meta='my test directory' tmptest /tmp/test
Catcli creates its catalog file in the current directory as catcli.catalog.
Printing the entire catalog as a tree is done with the command ls -r
$ catcli ls -r
top
└── storage: tmptest (my test directory) (nbfiles:3, free:3.7G/3.7G, date:2019-01-26 19:59:47)
├── a [nbfiles:3, totsize:72]
│ ├── 1 [size:24]
│ ├── 2 [size:24]
│ └── 3 [size:24]
├── b [nbfiles:3, totsize:87]
│ ├── 4 [size:29]
│ ├── 5 [size:29]
│ └── 6 [size:29]
└── c [nbfiles:3, totsize:33]
├── 7 [size:11]
├── 8 [size:11]
└── 9 [size:11]
The catalog can be walked with ls as if it was a normal directory
$ catcli ls
top
- storage: tmptest (my test directory) (nbfiles:3, free:3.7G/3.7G, date:2019-01-26 19:59:47)
$ catcli ls tmptest
storage: tmptest (my test directory) (nbfiles:3, free:3.7G/3.7G, date:2019-01-26 19:59:47)
- a [nbfiles:3, totsize:72]
- b [nbfiles:3, totsize:87]
- c [nbfiles:3, totsize:33]
$ catcli ls tmptest/b
b [nbfiles:3, totsize:87]
- 4 [size:29]
- 5 [size:29]
- 6 [size:29]
And files can be found using the command find
$ catcli find 9
c/9 [size:11, storage:tmptest]
When using the -b --script switch, a one-liner is generated
that allows to handle the found file(s)
$ catcli find 9 --script
c/9 [size:11, storage:tmptest]
op=file; source=/media/mnt; $op ${source}/c/9
Archive example
Let's consider a directory containing archive files:
$ ls -1 /tmp/catcli
catcli-0.3.1
v0.3.1.tar.gz
v0.3.1.zip
To enable the indexing of archive contents use
the -a --archive switch
$ catcli index -au some-name /tmp/catcli
Then any command can be used to explore the catalog as for normal
files but, by providing the -a --archive switch, archive content are displayed.
$ catcli ls some-name
storage: some-name (free:800G, total:1T)
- catcli-0.3.1 [nbfiles:11, totsize:80.5K]
- v0.3.1.tar.gz [size:24.2K]
- v0.3.1.zip [size:31.2K]
$ catcli ls -r some-name/v0.3.1.zip
v0.3.1.zip [size:31.2K]
$ catcli ls -ar some-name/v0.3.1.zip
v0.3.1.zip [size:31.2K]
