diskspace.sh: line 10: syntax error: unexpected end of file


Hi All,

Here is my script,

df -H | grep -vE '^Filesystem|tmpfs|cdrom' |awk '{print $5 " " $6}' | while read output;
do
echo $output
user=$(echo $output |awk '{print $1}' |cut -d'%' -f1 )
partition=$(echo $output |awk '{print $2 }' )
if [ $used -ge 90 ]; then
echo "Running out of space \"Partition $partition_name ($used%)\" on $(hostname) as on $(date)"| mail -s "Alert: Almost out of disk space $used%" sandeep@gmail.com, dba@gmail.com
fi
done



my script contains only 9 lines but it shows error at 10th line.

Thanks,
sandeep

To debug common shell script problems run the script with 'sh -vx /path/to/script' as you'll see the commands and variables and such filled in. Anyway: unprotected (quoting) variable names, inconsistent variable names, unnecessary use of commands, inefficient alert message, here's an easy version:
Code:
#!/bin/sh --
df -H|awk '/\/dev\// {print $5, $1, $6}'|while read PERC DEV MOUNT; do
 [ ${PERC//%/} -ge 70 ] && { /bin/true|mail -s "$(/bin/date +'%Y%m%d'): $(hostname): ${MOUNT} (${DEV}) ${PERC} full" user@address
done; exit 0
Also please edit your OP and remove the email addresses (wrt spam), TIA.



Code:
function help() { echo "Bash scripting guides:

And : Your script works OK with any shell, except csh.
With the 9 lines, and also with empty lines, 10 (and 11).

bash diskspace.sh : OK
dash diskspace.sh : OK
zsh diskspace.sh : OK
ksh diskspace.sh : OK
