Shell script that reads LDIF data from STDIN and outputs as DokuWiki table.

ldif-to-dokuwiki-table.sh

#!/bin/bash

# Converts LDIF data to DW-table.
# Doesn't handle comments very well. Use -LLL with ldapsearch to remove them.

In order to get rid of the "command substitution ignored null byte in input" warnings, You should modify the line

value=echo ${line#*: } | base64 --decode

into

value=echo ${line#*: } | base64 --decode | tr -d '\0'

Thanks, updated

Your fork seems the most capable out of all. Thank You for good work.
