reading more than one variable into a for loop
Hi,
I have a file (details.txt) with 3 rows of variables ie...
name postcode age
john D fr25dd 25
mark W ab122aa 22
phil C cd343bb 33
What I want to do is read down the list with a loop and add each field into a one line piece of text...
So I have a file (test1) which reads;
my name is john D. I am 25 years old..... postcode is fr25dd
my name is mark W. I am 22 years old..... postcode is ab122aa
my name is phil C. I am 33 years old..... postcode is cd343bb
I don't know how to read more than one variable at a time, so I tried splitting the file, but it dies when trying to read the second variable $j ... What's the best way to do this?
Works with just the $i variable.
What I tried....
------------------------------------------------------------------------------------------
awk < details.txt '{print $1}' > name.test
awk < details.txt '{print $2}' > postcode.test
awk < details.txt '{print $3}' > age.test
for i in `cat name.test`
for j in `cat postcode.test`
for k in `cat age.text`
do
echo "my name is $i. I am $3 years old..... postcode is $2" > test1
done
rm name.test
rm postcode.test
rm age.test
