Commands Not Found when Passed through SSH

Question

System:

Red Hat Enterprise Linux Server release 7.6 (Maipo), 3.10.0-957.el7.x86_64

GOAL:

Collect configurations for data from multiple servers to validate they are the same.

What Works:

ssh $SERVERNAME 'yum list installed | grep -E "krb|java|libkadm|realmd|oddjob|sssd|adcli"' >> $FILENAME

What Doesn't Work:

ssh $SERVERNAME 'adcli info domain.name' >> $FILENAME
ssh $SERVERNAME 'realm list' >> $FILENAME

Error Received:

bash: adcli: command not found

bash: realm: command not found

Full Script:

#!/bin/bash

DATE=`date '+%Y%m%d'`

SERVERLIST=(
#"server1.com"
"server2.com"
"server3.com"
#"server4.com"
"server5.com"
)

for SERVERNAME in ${SERVERLIST[*]}
do
        FILENAME=${SERVERNAME}-config.${DATE}
        ssh $SERVERNAME 'yum list installed | grep -E "krb|java|libkadm|realmd|oddjob|sssd|adcli"' >> $FILENAME
        ssh $SERVERNAME 'adcli info domain.name' >> $FILENAME
        ssh $SERVERNAME 'realm list' >> $FILENAME
        ssh $SERVERNAME 'cat /etc/sssd/sssd.conf' >> $FILENAME
done

Answer 1

GracefulRestart is almost certainly correct.

No verify, compare the output of $PATH between on-server exec and ssh to server exec:

[server2.com]# echo $PATH [jumpbox]# ssh server2.com 'echo $PATH'

If the path to 'adcli' & 'realm' are missing on the ssh $PATH env variable, then the simplest way to fix is to simply use the full path.
