Shell Programming and Scripting

Hi namishtiwari and zaxxon and all,
I really appreciate your patience...

Thank You ur code worked.

but it was just a sample code given.my actuall program is NOT working.
i wanted/used the same concept in one of my module of a Huge program.

here is my actual code,i wonder y it's not working.
the concept is same as our sample code.

#!/bin/sh
egrep '(Latch Hit)...' /oracle/zaheer/parts/part4 | awk '{print "Latch Hit "$9 " %"}'
set value=99
if [ $9 -lt $value ] ;
then
echo "Your latch it is $9 It is very is Low"
else
echo "You Have $9 latch hit which is Very Good"
fi

output:
$ ./latch.sh
Latch Hit 100.00 %
Your latch it is It is very is Low
Again wrong loop,again witout $9 value. YYYYY?i dont know...IM GOING MAD.

Please help me here....

why are you using set here remove set and give a try.

set value=99 -> remove set

Thanks
Namish

Hi namishtiwari,

If i remove set im getting the error..
and if i put "set" it's executing wrong loop...Oh God.

code:
egrep '(Latch Hit)...' /oracle/zaheer/parts/part4 | awk '{print "Latch Hit "$9 " %"}'
value=99
if [ $9 -lt $value ] ;
then
echo "Your latch it is $9 It is very is Low"
else
echo "You Have $9 latch hit which is Very Good"
fi
output:
$ ./latch.sh
Latch Hit 100.00 %
./latch.sh: test: argument expected

PLS HELP ME....
It's Urgent.. and Im going MAD hour after Hour....

Thanks

you are using the arguement $9 but where you are passing the value of that to the script.

Thanks

Nearly there. The $9 to awk means the 9th field in the input stream to awk. It is not the same as $9 in shell - the 9th parameter in the shell call.
Just save the percentage value, then format the output. Note the left sloping quotes around the egrep command sequence.
I've also deleted a ";" from the "if" statement.
(Script is untested but should show you the way).

#!/bin/sh
latch_hit=`egrep '(Latch Hit)...' /oracle/zaheer/parts/part4 | awk '{print $9}'`

set value=99

if [ ${latch_hit} -lt $value ]
then
echo "Your latch it is ${latch_hit} It is very is Low"
else
echo "You Have ${latch_hit} latch hit which is Very Good"
fi


Footnote:
Awk purists will be able to set $latch_hit with just awk commands.

Hi Methyle and All,
if u execute the following code:
i get the following error:

$ l.sh
l.sh: test: argument expected

Please HELP

You should play around testing your with your shell and the test command, if you better use 1 or 2 brackets on each side, which kind of arithmetic operators you can use (-eq, -gt, <=, ==, =, <>, ...) and if you can use something similar to typeset to declare variable values as integer for example, which your shell doesn't seem to know.

I tried sh/bash, ksh and each of them knows "typeset" for example. What OS are you on and what kind of shell are you using (I saw the shebang, but check the package's/binary's version maybe)?
