Why do I get the error on the second example?.

This works:
if [[ "a" = "a" ]];then
> echo "true"
> else
> echo "false"
> fi
true
This doesn't, and gets the error shown:
if [[ "a" = "a"...

I think profile variables need to be exported and are not getting to your script. Can you do an echo "Output=$OUTPUT" inside your script to check?

Things inside brackets are a "test". -z tests "$name" to see if its length is zero.

from "man test":
-z String1
Returns a True exit value if the length of the String1...

if [ $a = $b ]; then echo "variables are equal"; fi
Worked for me.

Go here and look in the sample chapter for diffdate. (Hi Chris)

awk '{print "blah bli" $0 "blu"}' readfile.txt > outfile.txt
This is how I would do it.

You could change your print... to:
print substr($9,index($9,".")+1)

That answers it. Thank you very much!

awk '{A=$1;B=$2;C=C+A*B;print A" x "B" = "A*B};END{print "Total = "C}' filename

awk '{A=$1;B=$2;print A" x "B" = "A*B}' filename

But not in cygwin or aix.

Are you familiar with awk?
You could try
awk '{print $1" x "$2" = "$1*$2}' filename
$1 would be the first field, $2 would be the second, etc.

$ ksh
$ echo "\047"0"\047"
result:
8'

for f in `cat listoffiles`
do
grep "specific pattern" "$f"
done

depending on what you want from the grep, you might want a "grep -l..."

You are very close! Try putting "lines", "chars" and "words" in quotes.
