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