[SOLVED] Script for SerialNumber

anandrhce · 03-12-2014, 02:54 AM

Can someone help to get the expected output:

Script:
for i in `cat a`; do ssh -q $i -t " /usr/bin/sudo /usr/sbin/dmidecode -s system-serial-number;hostname" ; done

Current Output:

SerialNumber
ServerName

Expected Output:

SerialNumber - ServerName

I assume that by "expected output" you mean "desired output", as the script does exactly what it's supposed to do. It runs two separate commands, and the output from each appears on a separate line.

How about piping the output from dmidecode through tr and have it replace the newline character with a space?

Code:

for i in `cat a`; do ssh -q $i -t "/usr/bin/sudo /usr/sbin/dmidecode -s system-serial-number | tr '\n' ' ' ; hostname" ; done

This will cause the output from the dmidecode and hostname commands to appear on the same line.

You could also do

Code:

for i in `cat a`; do ssh -q $i -t ' /usr/bin/sudo echo "$(/usr/sbin/dmidecode -s system-serial-number) $(/bin/hostname)" '; done
