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 -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

Installation

Getting help

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