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 ? Well catcli indexes external media in a catalog 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

• Save catalog to json for easy versioning with git

• Command line interface FTW

• Store files and folders sizes

• Store md5 hash of files

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/folders 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 example 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

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.

Four different types of entry are present in a catalog:

• top node: this is the root of the tree

• storage node: this represents some indexed storage (a DVD, an external hard drive, an USB drive, some arbitrary directory, …)

• dir node: this is a directory

• file node: this is a file

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. The -u switch tells catcli to also store (and calculate) the total size of each directory.

Walk indexed files with ls

A catalog can be walked using the command ls as if the media was mounted.

File/folder separator is /

$ catcli ls tmp/a/b/c

See the example for more.

Find files

Files and directories can be found based on their names using the find command.

See the example for more.

Display entire tree

The entire catalog can be shown using the tree command.

See the example 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

Example

Let’s first create some files and directories:

$ mkdir -p /tmp/test/{a,b,c}
$ touch /tmp/test/a/{1,2,3}
$ touch /tmp/test/b/{4,5,6}
$ touch /tmp/test/c/{7,8,9}
$ ls -R /tmp/test
/tmp/test:
a  b  c

/tmp/test/a:
1  2  3

/tmp/test/b:
4  5  6

/tmp/test/c:
7  8  9

First this directory is indexed by catcli as if it was some kind of external storage:

$ catcli index --meta='my test directory' -u tmptest /tmp/test

Catcli has created 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 (free:183.7G, total:200.0G) (my test directory)
    ├── b [nbfiles:3]
    │   ├── 4 [size:0]
    │   ├── 5 [size:0]
    │   └── 6 [size:0]
    ├── a [nbfiles:3]
    │   ├── 1 [size:0]
    │   ├── 3 [size:0]
    │   └── 2 [size:0]
    └── c [nbfiles:3]
        ├── 7 [size:0]
        ├── 8 [size:0]
        └── 9 [size:0]

The catalog can be walked with ls as if it was a normal directory

$ catcli ls
top
- storage: tmptest (free:2.6G, total:2.6G) (my test directory)

$ catcli ls tmptest
storage: tmptest (free:3.7G, total:3.7G) (my test directory)
- a [nbfiles:3]
- b [nbfiles:3]
- c [nbfiles:3]

$ catcli ls tmptest/b
b [nbfiles:3]
- 4 [size:0]
- 5 [size:0]
- 6 [size:0]

And files can be found using the command find

$ catcli find 9
test/c/9 [size:0]

When using the -s switch, a one-liner is generated that allows to handle the found file(s)

$ catcli find 9 -s
test/c/9 [size:0]
op=file; source=/media/mnt; $op ${source}/test/c/9
