[SOLVED] bash ldapsearch take input from file

Issue

I have a simple ldapsearch bash script to return the user email when searched by ID. I made it take and argument as its input since at the time I only needed to run it once or twice.

I'm wondering can I adapt it and take input from a file like .txt and append the outputs to another file.

This is what i have:

#!/bin/bash

if [ "$1" = "" ]; then
    echo "how to: searchID.sh <userID>"
    exit 1
fi
ldapsearch -x -b '' -LLL -h ldaphost.com -p 255 uid=$1 mail >> outputs.txt

Instead of running it manually like: ./searchID.sh I0FT45

I want it to take input from a file with many ID's like:

I0001F
IGLFK7
I37462
I4593N

And run it for all those entries. Any help is very much appreciated

Solution

if your usernames are xargs "safe" (no space, no quote) then you can do something like this:

xargs -I {} \
    ldapsearch -x -b '' -LLL -h ldaphost.com -p 255 uid={} mail \
    < file.in \
    >> file.out
