Problem with for loop/sed ?
I have a hostnames file which has:
$ cat hostnames.txt
serverxx1
serverxx2
serverxx3

My script:
#!/bin/sh
fileA=build.xml
for i in ./hostnames.txt ; do
sed 's/createConfig machine="Machine"/createConfig machine=" '$i' "/g' "$fileA" > ./tmpfile
done

FileA has:
createConfig machine="Machine"

Output should have FileA:
createConfig machine="serverxx1"
createConfig machine="serverxx2"
createConfig machine="serverxx3"

But I am getting error as
sed: -e expression #1, char 58: Unknown option to `s'

If I change '$i' to just $i , it's replacing Machine with $i not it's value.

Can somebody please help me - if I am using the sed/for properly?

Thankyou
chiru_h

SYSTEMD-MACHINE-ID-COMMIT.SERVICE(8)			 systemd-machine-id-commit.service		      SYSTEMD-MACHINE-ID-COMMIT.SERVICE(8)

NAME

       systemd-machine-id-commit.service - Commit a transient machine ID to disk

SYNOPSIS

       systemd-machine-id-commit.service

DESCRIPTION

       systemd-machine-id-commit.service is an early boot service responsible for committing transient /etc/machine-id files to a writable disk
       file system. See machine-id(5) for more information about machine IDs.

       This service is started after local-fs.target in case /etc/machine-id is a mount point of its own (usually from a memory file system such
       as "tmpfs") and /etc is writable. The service will invoke systemd-machine-id-setup --commit, which writes the current transient machine ID
       to disk and unmount the /etc/machine-id file in a race-free manner to ensure that file is always valid and accessible for other processes.
       See systemd-machine-id-setup(1) for details.

       The main use case of this service are systems where /etc/machine-id is read-only and initially not initialized. In this case, the system
       manager will generate a transient machine ID file on a memory file system, and mount it over /etc/machine-id, during the early boot phase.
       This service is then invoked in a later boot phase, as soon as /etc has been remounted writable and the ID may thus be committed to disk to
       make it permanent.
