you need square brackets around your test, like this:

if $used -ge $threshold ;
then
echo stuff
fi

the open bracket is actually an alias for the test command.

sorry - I see the square brackets are getting swallowed by the web page...

Put in an echo $threshold and echo $used just before the if statement. If either one is blank, that's the problem.

You probably need to check each one for the case where it's blank, such as "if ; " and take appropriate action.

ok, web page broke my post again...

if [

Hi,

When I tested your script, but with the lines:

print 
"<$used> <$threshold>" 

if $used -ge $threshold ; # at 

this point am getting error#

the following was displayed:

<Iused 4645> <70>

It would appear the "used" calculation is incorrect.

Personally, I prefer the double-brackets, for an if expression, since it is far more forgiving with minor errors.

Regards,
George

Try:

used=`df -k /opt | awk 
'NR==2{print $5}'`

and

if [[ $used -ge $threshold ]]; then
