Yes, I am using the bash, but should I use something else to run the commands?
I did run your script, but it didn't do anything.
Didn't get an error and no output files.
Seems like it didn't do anything.

Apologies, your command does work.
thx very much !!
but is it also possible to echo which command is going to run and date in front of every command in the log file?
I can't tell you what interpreter you should use to run your commands other than to say that the interpreter used has to be an interpreter that recognizes the commands it is being asked to run. You are the one who knows what is in the cmd* files. You are the one who knows if those files have a first line of the form #!interpreter. You are the one who knows if the cmd* files have been marked executable or are just readable. Without this information, I don't know what you should do. It just seemed strange that you were writing this script using bash, but using a Bourne shell to run the cmd* files. (Of course, you haven't said what system you're using; so sh and bash may be the same shell.)

Do you want all of the output from all of the cmd* files in one output file? Do you want the standard output from all of the cmd* files in one output file and standard error output from all of the cmd* files in a different output file? Or, do you want the standard output and standard error output for each cmd* file in separate output files (like the script I gave you currently does)?

Do you want the output showing which cmd* file is being started and the timestamp written to the same file as the standard output for the cmd* file that is about to run, to the standard output of the entire script, or to a different log file?

rancid-run

rancid-run(1)						      General Commands Manual						     rancid-run(1)

NAME

       rancid-run - run rancid for each of the groups

SYNOPSIS

       rancid-run [-V] [-f rancid.conf] [-f rancid.conf] [-m mail_rcpt] [-r device_name] [group [group ...]]

DESCRIPTION

       rancid-run is a sh(1) script to run rancid(1) for a set of rancid group(s).

       rancid-run reads rancid.conf(5) to configure itself, then uses control_rancid(1) to run rancid(1) for each rancid group.  The set of rancid
       groups can either be provided as command-line arguments or via the LIST_OF_GROUPS variable in rancid.conf(5),  if  the  group  argument	is
       omitted.

       A  lock	file  is  maintained  per-group  to  prevent  simultaneous  runs  for a given group by rancid-run(1).  The lock file will be named
       .<group>.run.lock and will be located in /var/lib/rancid.

       A log file is produced under $LOGDIR/logs for each rancid group processed.  The file name will be <group>.YYYYMMDD.HHMMSS (year month day .
       hour minute second).

       rancid-run is normally used to run rancid from cron(8).	For example:

		 0 * * * *	/usr/local/rancid/bin/rancid-run

       The command-line options are as follows:

       -V     Prints package name and version strings.

       -f rancid.conf
	      Specify an alternate configuration file.

       -m mail_rcpt
	      Specify  the  recipient  of  diff  mail,	which  is  normally  rancid-<group>.  The argument may be a single address, multiple comma
	      separated addresses, or -m may be specified multiple times.

       -r device_name
	      Run rancid for a single device, device_name.  device_name should be name, as it appears in a group's router.db.  The device must	be
	      marked  "up".   If  a  group  is	not  specified	on the command-line, rancid will be run against any group in which the device_name
	      appears.

	      The -r option alters the subject line of the diff mail.  It will begin with <group name>/<device name> rather than  just	the  group
	      name alone.

ENVIRONMENT

       rancid-run utilizes the following environment variables from rancid.conf(5).

       BASEDIR
	      Location of group directories, etc.  This is set to the "localstatedir" by the configure script at installation time.

       LIST_OF_GROUPS
	      List of rancid groups to collect.

       PATH   Search path for utilities.

       TMPDIR Directory to hold temporary files.

ERRORS

       If  rancid  fails  to  run or collect a device's configuration, the particular group's log file (mentioned above) should be consulted.  Any
       errors produced by the revision control system (CVS or Subversion) or any of the rancid scripts should be included there, whether they be a
       botched	cvs  tree,  login  authentication failure, rancid configuration error, etc.  If the log file produces no clues, the next debugging
       step should be run the commands manually.  For example, can the user who runs rancid login to the device with 'clogin hostname', and so on.

FILES

       $BASEDIR/etc/rancid.conf
	      rancid-run configuration file.
