I wrote a script using 'expect' tool to change the password of my login id, every fortnight. And I had put it as a cron job.
The cron job is throwing an error

This isn't the usual problem that a shell script runs from the command line and not the cron. It's a little different.
Among other things, the shell scrip executes my .profile to set a bunch of variables. It then does an env to ensure that it ran OK.
There are echos in the shell script and... (2 Replies)

Any help would be really appreciated.

systemd-run
SYSTEMD-RUN(1) systemd-run SYSTEMD-RUN(1)NAME
systemd-run - Run programs in transient scope or service units
SYNOPSIS
systemd-run [OPTIONS...] COMMAND [ARGS...]
DESCRIPTION
systemd-run may be used to create and start a transient .service or a .scope unit and run the specified COMMAND in it.
If a command is run as transient service unit, it will be started and managed by the service manager like any other service, and thus show
up in the output of systemctl list-units like any other unit. It will run in a clean and detached execution environment. systemd-run will
start the service asynchronously in the background and immediately return.
If a command is run as transient scope unit, it will be started directly by systemd-run and thus inherit the execution environment of the
caller. It is however managed by the service manager similar to normal services, and will also show up in the output of systemctl
list-units. Execution in this case is synchronous, and execution will return only when the command finishes.
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a short version string and exits.
--user
Talk to the service manager of the calling user, rather than the service manager of the system.
--system
Talk to the service manager of the system. This is the implied default.
--scope
Create a transient .scope unit instead of the default transient .service unit.
--unit=
Use this unit name instead of an automatically generated one.
--description=
Provide description for the unit. If not specified, the command itself will be used as a description. See Description= in
systemd.unit(5).
--slice=
Make the new .service or .scope unit part of the specified slice, instead of the system.slice.
--remain-after-exit
After the service's process has terminated, keep the service around until it is explicitly stopped. This is useful to collect runtime
information about the service after it finished running. Also see RemainAfterExit= in systemd.service(5).
--send-sighup
When terminating the scope unit, send a SIGHUP immediately after SIGTERM. This is useful to indicate to shells and shell-like processes
that the connection has been severed. Also see SendSIGHUP= in systemd.kill(5).
All command-line arguments after the first non-option argument become part of the commandline of the launched process. If a command is run
as service unit, its first argument needs to be an absolute binary path.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
EXAMPLE
The following command will log the environment variables provided by systemd to services:
# systemd-run env
Running as unit run-19945.service.
# journalctl -u run-19945.service
