  --help                  Show help                      [boolean]

  -r, --row-separator     Row delimiter                  [string] [default: ">"]

Practical Usage Example

In this example, we're going to list all enabled NGINX sites. This assumes that all site configuration files are named according to the site's domain name. We'll also be pulling relevant information from a JSON deployment manifest file.

#!/bin/bash

FILES=(/etc/nginx/sites-enabled/*)
LAST_POS=$(( ${#FILES[*]} - 1 ))
LAST=${FILES[$POS]}
TBL_STR="DOMAIN | VERSION | PATH | LAST DEPLOYMENT>"

for FILE in "${FILES[@]}";
do
  DOMAIN=$(basename "$FILE")
  DEPLOY_DIR=$(grep -m1 -Poe 'root \K[^; ]+' $FILE)
  DEPLOY_MANIFEST="${DEPLOY_DIR}/deployment.json"
  DEPLOY_VER="N/A"
  DEPLOY_DATE="N/A"

  if [ -f $DEPLOY_MANIFEST ];
  then
    DEPLOY_VER=$(jq -r ".version" $DEPLOY_MANIFEST)
    DEPLOY_DATE=$(jq -r ".date" $DEPLOY_MANIFEST)
  fi

  TBL_STR+="${DOMAIN} | ${DEPLOY_VER} | ${DEPLOY_DIR} | ${DEPLOY_DATE}"

  if [[ $FILE != $LAST ]];
  then
    TBL_STR+=">"
  fi
done

asciitable -i "${TBL_STR}"
