Checking the status of the script on remote machine
Hi!
I have a script, which calls another script on a remote machine using ssh.
I need to check if the remote running script is succesful. If it is succesful I need to continue the for loop (run it on another machine) or break the loop.
Please let me know if anyone has an idea on checking the status of the script on remote machine .
My script is as below.
./sshlogin.exp $passw $host $username statement would trigger the second script on a remote machine.
Code:
#!/usr/bin/sh
##Take input from the user
c=d=e=0
while [ "$host_name" != done ]
do
echo "Please enter the host_name"
read host_name
if [ "$host_name" = done ] ; then break; fi
store_hostname[$c]=$host_name
#Check if hostname is correct
validHost=`host $host_name | grep 'not found'`
if [ "$validHost" != "" ] ; then
echo "Checking Host" 'Host cannot be resolved. Please check your hostname'
exit 1
fi
c=$(( c + 1 ))
echo "Please enter the username"
read username
store_username[$d]=$username
d=$(( d + 1 ))
echo "Please enter the password"
read -s password
store_password[$e]=$password
e=$(( e + 1 ))
done
echo ${store_hostname[0]}
len=${#store_hostname[*]}
echo $len
for (( i=0; $i < $len; i++ ))
do
host=`echo ${store_hostname[$i]}`
passw=`echo ${store_password[$i]}`
username=`echo ${store_username[$i]}`
ssh -q host@username date
./scplogin.exp $passw $host $username
./sshlogin.exp $passw $host $username
if [ "$?" = 1 ] ; then break; fi
done

cd-hit-para.pl - divide a big clustering job into pieces to run cd-hit or cd-hit-est jobs
SYNOPSIS
cd-hit-para.pl options
DESCRIPTION
This script divide a big clustering job into pieces and submit jobs to remote computers over a network to make it parallel. After
all the jobs finished, the script merge the clustering results as if you just run a single cd-hit or cd-hit-est.
You can also use it to divide big jobs on a single computer if your computer does not have enough RAM (with -L option).
Requirements:
1 When run this script over a network, the directory where you
run the scripts and the input files must be available on all the remote hosts with identical path.
2 If you choose "ssh" to submit jobs, you have to have
passwordless ssh to any remote host, see ssh manual to know how to set up passwordless ssh.
3 I suggest to use queuing system instead of ssh,
I currently support PBS and SGE
4 cd-hit cd-hit-2d cd-hit-est cd-hit-est-2d
cd-hit-div cd-hit-div.pl must be in same directory where this script is in.
Options
-i input filename in fasta format, required
-o output filename, required
--P program, "cd-hit" or "cd-hit-est", default "cd-hit"
--B filename of list of hosts,
requred unless -Q or -L option is supplied
--L number of cpus on local computer, default 0
when you are not running it over a cluster, you can use this option to divide a big clustering jobs into small pieces, I suggest you
just use "--L 1" unless you have enough RAM for each cpu
--S Number of segments to split input DB into, default 64
--Q number of jobs to submit to queue queuing system, default 0
by default, the program use ssh mode to submit remote jobs
--T type of queuing system, "PBS", "SGE" are supported, default PBS
--R restart file, used after a crash of run
-h print this help
More cd-hit/cd-hit-est options can be speicified in command line
