Shell Programming and Scripting

OK this one sounds like it should be a natural...

it must be possible to send a number say 200 to a text file and later use it as a variable?

yada yada > file.txt

how would I retrieve that number to use as a variable? Is this possible?

looking for something like this ...

just a pointer

Code:

> echo "200" > ert
> var=`cat ert`
> echo $var
200

ah thanks... I'd tried that but not with quotation marks!!!

quotes is not at all needed

Code:

echo 200 > ert
var=`cat ert`
echo $var
200

I've sat here for an hour trying to get that variable to show up in an awk...

Code:

cat gzipsize.txt | awk '{print "echo",$1,$2} > master.txt

I've got a variable in my script called $size and i want to print it after the second field from the text file.

Could you please give me a clue on how to effectively insert variables from my script into the awk?

My book seems to have no examples of this and the many ways I've got from googling has led down blind paths that didn't work.

just to display the command line

Code:

wc -l < zom.c | awk '{ print "echo " $1 " > 1.txt" }'

and execute it in the run

Code:

wc -l < zom.c | awk '{ print "echo " $1 " > 1.txt" }' | ksh
