Yes, you are right, with the "w" you can write the output to a file.
but the syntax should be as follows:
Code:
w TEMPLATE $FILENAME
Where "TEMPLATE" will be the outputfile.
Did yo realize that you have used the FILENAME variable at both, the "read" as well as the input file name?
Well... guess I'll try "w" next time now I know how it works ... does it have any difference to > after all?
As for the FILENAME var... I actually read it from the CSV archive (it is one of the columns) and then I apply it as the name of the output file (that's what I did on my finished script... but right, at my first example it was (wrongly) on the input file). That "while read" now reads:
Code:
while read VAR1 VAR2 VAR3 FILENAME; do
sed -n -e "s/VAR1/$VAR1/g"\
-e "s/VAR2/$VAR2/g"\
-e "s/VAR3/$VAR3/g"\
TEMPLATE > $FILENAME
done < $CSV
Again, this is just an example on who it looks now... I'll post the actual script later

One last thing...
one of the columns on the csv file has values with spaces on it (i.e: interface name) but sed brings that around quotes (i.e: "interface name") and in some cases, it brings in quotes and adds a string to the end (i.e: "interface name"ESS).
What gives? Is there a way to tell sed not to do that?
By the way.... as promissed, here is the script that is working now:
Code:
#!/bin/bash
current_ifs=$IFS; #backup original IFS
IFS=,
echo "reading $1"
# while and sed are broken down for readability
