[root@oracle ~]# sh /root/test/tests/test/sysos.sh
/root/test/tests/test/sysos.sh: line 9: /usr/sbin/sendmail: Text file busy

Post the contents of your /root/test/tests/test/sysos.sh?

Thanks unspawn, here it is :

[root@oracle ~]# cat /root/test/tests/test/sysos.sh
#!/bin/bash

set -xv

LOGFILE=/home/oracrp/test/sysos.log

echo "Logging system log at $(date)" >> "$LOGFILE"
# log vmstat. 3 * 5 second interval. Probably better than 1 second as it
# gives more time to average out the load analysis.

sar 1 5 >> $LOGFILE

#/usr/sbin/sendmail user@company.com << EOM
#From

BA
#To:Yusuf
#Subject:$(date +%d-%b-%Y) Alert Log Error

#EOM

# make a blank line between commands to help readability.
echo "" >> "$LOGFILE"

top -b -n 1 >> "$LOGFILE"
echo "" >> "$LOGFILE"

w >> "$LOGFILE"

#netstat -tap >> "$LOGFILE"
echo "" >> "$LOGFILE"
echo "" >> "$LOGFILE"

#/usr/sbin/sendmail user@company.com << EOM
#From

BA
#To:Yusuf
#Subject:$(date +%d-%b-%Y) SYSOS

#EOM

cat $LOGFILE | mail -s "Contents of my LOGFILE" user@company.com

Thanks
Yusuf

I would edit your post and remove your email unless you like spam.

I can't edit it - only mods can edit other peoples posts

You just need to use the edit button under your post and delete it.

Maybe wrong use of sendmail command? Here's my annotated version of your script:

Code:

#!/bin/sh --
# Set debug and or error mode when testing:
# set -xe
# Logfile name.
LOGFILE=/home/oracrp/test/sysos.log
# Subject of e-mail.
MAILSUBJ="Contents of ${LOGFILE//*\//}"
# Hostname in e-mail subject
MAILHOST=`hostname`
# E-mail recipient
MAILRCP="user@company.com"
# Function to echo a blank line, shorter than echoing all the time.
blank() { echo >> "$LOGFILE"; }
# Function to make message go to stderr.
error() { echo "$*" > /proc/self/fd/2; }
# No need to check logfile existence or clean up afterwards since we append to it.
echo "Logging system log at $(date)" >> "$LOGFILE"
# SAR likes a binary output file. Log to it, then read from it.
sar -o /tmp/sar.out 1 5 >/dev/null 2>&1 && sar -f /tmp/sar.out >> $LOGFILE; blank
top -b -n 1 >> "$LOGFILE"; blank; w >> "$LOGFILE"; blank
# Using '-n' with netstat makes it not resolve IP addresses which is faster.
# netstat -ntp >> "$LOGFILE"; blank
# Check if the logfile is in use which shouldn't happen.
/sbin/fuser "$LOGFILE" >/dev/null 2>&1; case "$?" in
 0) # Log who is bugging us.
    /sbin/fuser "$LOGFILE" | while read line; do
     error "Process using "${LOGFILE//*\//}": $line"; done; exit 1;;
 *) # Don't rely on /bin/mail ('mailx' package), use default MTA location.
    (echo "Subject: $MAILSUBJ on $MAILHOST"; \
    echo; cat "$LOGFILE") | /usr/sbin/sendmail -t $MAILRCP;;
esac
# Always exit
exit 0

It's untested so YMMV(VM) as usual. Notice that if you do

Code:

(echo "Subject: $MAILSUBJ on $MAILHOST"; echo; sar -f /tmp/sar.out; echo; top -b -n 1; echo etc etc) | /usr/sbin/sendmail -t $MAILRCP

you don't even need a logfile to write to unless you need to save, append or edit results before sending.

Thanks a lot unspawn,, that really helped me..
