Problem with writing into a file through shell script
Hi all,

I have a shell script which I use to login to the server from the client and then from the server I run a bunch of other scripts to complete my task. I am having problems with the script below-
Code:
#!/bin/bash

while read line
do
connections=`echo $line | cut -d " " -f 1`
period=`echo $line | cut -d " " -f 2`
testcaseid=`echo $line | cut -d " " -f 3`

ssh  192.168.1.202 <<EOF
sudo ./collectlcpu.sh $period $connections $testcaseid&
#sudo ./oprofile.sh $period $connections $testcaseid
sudo ./interrupt.sh $period $connections $testcaseid
#sleep 10
exit
EOF

./httperf1.sh $period $connections $testcaseid&
sleep 12

ssh  192.168.1.202  <<EOF
sudo killall collectl
sudo killall collectlcpu.sh
sudo killall interrupt.sh
sudo opcontrol --shutdown
sudo killall oprofile.sh
#killall pfmon.sh
#killall pfmon
exit
EOF
done  <  "/home/joydeep/input.txt"

sleep 30

The interrupt script is given below-
Code:
#!/bin/bash

dt=`date +%m%d%l%M`
dtstring=`echo $dt|sed 's/ //g'`

period=$1
connections=$2
testcaseid=$3
echo "STARTING THE INTERRUPT SCRIPT"
outputfile0="output_period_""Core2_""$period""_""connections""_""$connections""_""$testcaseid""_""$dtstring"".txt"
outputfile2="output_period_""Core0_""$period""_""connections""_""$connections""_""$testcaseid""_""$dtstring"".txt"
for i in 1 2 3 4 5 6 7 8 9 10 11 12
do
line1=`cat /proc/interrupts | grep eth3-TxRx-0`
line2=`cat /proc/interrupts | grep eth2-TxRx-0`
nohup echo $line1 >> /home/joydeep/results/interrupt/samesocket/data_cache_misses/"$outputfile0"&
nohup echo $line2 >> /home/joydeep/results/interrupt/samesocket/data_cache_misses/"$outputfile2"&
sleep 1
done
echo "END OF THE INTERRUPT SCRIPT"

The problem is that the script is not writing the files in /home/joydeep/results/interrupt.

Thanks,
Joydeep

uudemon.cleanu

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
