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
  • 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
  • Tag your different storages with additional information

Quick start:

# install catcli with pip
sudo pip3 install catcli
# index a directory in the catalog
catcli index -u --meta='some description' log /var/log
# display the content
catcli tree
# 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

To install run:

$ sudo pip3 install catcli

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
$ sudo pip3 install -r requirements.txt
$ 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 tree
  • 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> -u <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. See the examples for more.

Display entire tree

The entire catalog can be shown using the tree 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 storage
  • edit - 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. If using -c --hash, only new files are re-hashed.

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 tree

$ catcli tree
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]
