[solved] Dsh command : Execution Problems with Cron
Hi,
On linux cluster, i created a script to delete all temp files older than 5 days.
i am able to execute the script "dsh -ea script.ksh" in management node directly
But when i schedule "dsh -ea script.ksh" in crontab in management node it tells dsh command not found.
Hi All,
I have the following requirement. In a directory i get files from external source. I at regular intervals check that directory for any incoming files.
The file name is underscore delimited.
Such as:
aaa_bbb_ccc_ddd_eee_fff.dat
I am using awk and and splitting the file name. ... (4 Replies)
I tried to compare two sorted files with comm command which contain floating values as:
RECT 0 9.8 8.70 7.8 in first file & RECT 0 9.80 8.7 7.80 in second file.
comm -3 first_file second_file should give a empty file but it does not.
Is there a way to compare these two files correctly... (4 Replies)

Hi all!!
I have a nerve-wracking concept (probably for me!!) which is not understood. My crontab entry looks this way.

But cron gets started occasionally. Sometimes it does. Sometimes it does not. And sometimes it hangs in the middle (I... (1 Reply)

So I've been tasked with creating a shell script to run in a cron every few minutes to check duplex settings on my eth0 nic card. I would like for the server to send a wall message to whoever is on the console or in a terminal session. Below is what I have so far.

ganeti-listrunner(8) Version 2.5.2 ganeti-listrunner(8)NAME
ganeti-listrunner - Run commands in parallel over multiple machines
SYNOPSIS
ganeti-listrunner -l logdir {-x executable | -c shell-cmd} {-f hostfile | -h hostlist} [-a aux-file] [-b batch-size] [-u username] [-A]
DESCRIPTION
ganeti-listrunner is a tool to run commands in parallel over multiple machines. It differs from dsh or other tools in that it asks for the
password once (if not using ssh-agent) and then reuses the password to connect to all machines, thus being easily usable even when public
key authentication or Kerberos authentication is not available.
It can run either a command or a script (which gets uploaded first and deleted after execution) on a list of hosts provided either via a
file (one host per line) or as a comma-separated list on the commandline. The output (stdout and stderr are merged) of the remote execution
is written to a logfile. One logfile per host is written.
OPTIONS
The options that can be passed to the program are as follows:
-l logdir
The directory under which the logfiles files should be written.
-x executable
The executable to copy and run on the target hosts.
-c shell-cmd
The shell command to run on the remote hosts.
-f hostfile
The file with the target hosts, one hostname per line.
-h hostlist
Comma-separated list of target hosts.
-a aux-file
A file to copy to the target hosts. Can be given multiple times, in which case all files will be copied to the temporary directory.
The executable or the shell command will be run from the (temporary) directory where these files have been copied.
-b batch-size
The host list will be split into batches of batch-size which will be processed in parallel. The default if 15, and should be
increased if faster processing is needed.
-u username
Username to connect as instead of the default root username.
-A Use an existing ssh-agent instead of password authentication.
--args Arguments to pass to executable (-x).
EXIT STATUS
The exist status of the command will be zero, unless it was aborted in some way (e.g. ^C).
EXAMPLE
Run a command on a list of hosts:
listrunner -l logdir -c "uname -a" -h host1,host2,host3
Upload a script, some auxiliary files and run the script:
listrunner -l logdir -x runme.sh
-a seed.dat -a golden.dat
-h host1,host2,host3
