tablizer - Manipulate tabular output of other programs

Tablizer can be used to re-format tabular output of other programs. While you could do this using standard unix tools, in some cases it's a hard job.

Let's take this output:

% kubectl get pods -o wide
NAME                        READY   STATUS    RESTARTS      AGE
repldepl-7bcd8d5b64-7zq4l   1/1     Running   1 (69m ago)   5h26m
repldepl-7bcd8d5b64-m48n8   1/1     Running   1 (69m ago)   5h26m
repldepl-7bcd8d5b64-q2bf4   1/1     Running   1 (69m ago)   5h26m

But you're only interested in the NAME and STATUS columns. Here's how to do this with tablizer:

% kubectl get pods | tablizer 
NAME(1)                      READY(2) STATUS(3)  RESTARTS(4)    AGE(5)
repldepl-7bcd8d5b64-7zq4l    1/1      Running    1 (69m ago)    5h26m
repldepl-7bcd8d5b64-m48n8    1/1      Running    1 (69m ago)    5h26m
repldepl-7bcd8d5b64-q2bf4    1/1      Running    1 (69m ago)    5h26m

% kubectl get pods | tablizer -c 1,3
NAME(1)                      STATUS(3)
repldepl-7bcd8d5b64-7zq4l    Running
repldepl-7bcd8d5b64-m48n8    Running
repldepl-7bcd8d5b64-q2bf4    Running 

Another use case is when the tabular output is so wide that lines are being broken and the whole output is completely distorted. In such a case you can use the -o extended | -X flag to get an output similar to \x in psql:

% kubectl get pods | tablizer -X
    NAME: repldepl-7bcd8d5b64-7zq4l
   READY: 1/1
  STATUS: Running
RESTARTS: 1 (71m ago)
     AGE: 5h28m

    NAME: repldepl-7bcd8d5b64-m48n8
   READY: 1/1
  STATUS: Running
RESTARTS: 1 (71m ago)
     AGE: 5h28m

    NAME: repldepl-7bcd8d5b64-q2bf4
   READY: 1/1
  STATUS: Running
RESTARTS: 1 (71m ago)
     AGE: 5h28m

Tablize can read one or more files or - if none specified - from STDIN.

You can also specify a regex pattern to reduce the output:

% kubectl get pods | tablizer q2bf4
NAME(1)                      READY(2) STATUS(3)  RESTARTS(4)    AGE(5)
repldepl-7bcd8d5b64-q2bf4    1/1      Running    1 (69m ago)    5h26m

Sometimes a filter regex is to broad and you wish to filter only on a particular column. This is possible using -F:

% kubectl get pods | tablizer -n -Fname=2
NAME                            READY   STATUS  RESTARTS        AGE
repldepl-7bcd8d5b64-q2bf4       1/1     Running 1 (69m ago)     5h26m

Here we filtered the NAME column for 2, which would have matched otherwise on all rows.

There are more output modes like org-mode (orgtbl) and markdown.

Installation

There are multiple ways to install tablizer:

• Go to the latest release page, locate the binary for your operating system and platform.

  Download it and put it into some directory within your $PATH variable.

• The release page also contains a tarball for every supported platform. Unpack it to some temporary directory, extract it and execute the following command inside:

  sudo make install
  

• You can also install from source. Issue the following commands in your shell:

  git clone https://github.com/TLINDEN/tablizer.git
  cd tablizer
  make
  sudo make install
  

If you do not find a binary release for your platform, please don't hesitate to ask me about it, I'll add it.

Documentation

The documentation is provided as a unix man-page. It will be automatically installed if you install from source. However, you can read the man-page online:

https://github.com/TLINDEN/tablizer/blob/main/tablizer.pod

Or if you cloned the repository you can read it this way (perl needs to be installed though): perldoc tablizer.pod.

If you have the binary installed, you can also read the man page with this command:

tablizer --man

Getting help

Although I'm happy to hear from tablizer users in private email, that's the best way for me to forget to do something.
