Hello Everybody,

I have a file with data like this

Code:
8z:1
15y:0
7x:0
12w:1
...
...

I would like read each line through a loop and will needing to get the input from each line like this
Code:
For 8z:1; a=8,b=1
    15y:0; a=15,b=0
      7x:0; a=7,b=0

Hi,

Not sure about your output, but try this:
Code:
$ perl -aF: -ne '$input = join(":", @F); chomp $input; print "For $input", "; ", "a=", int($F[0]), ",", "b=", int($F[1]), "\n";' infile
For 8z:1; a=8,b=1
For 15y:0; a=15,b=0
For 7x:0; a=7,b=0
For 12w:1; a=12,b=1

Regards,
Birei

Try something like:
Code:
while IFS=: read a b
do
  a=${a%?}
  echo $a
  echo $b
done < file

Try something like...
Code:
$ echo '8z:1
> 15y:0
> 7x:0
> 12w:1' | while read my_row
> do
> eval $(echo $my_row|awk -F '[^0-9]:' '{print "a=" $1 ORS "b=" $2}')
> echo do something with $a and $b
> done
do something with 8 and 1
do something with 15 and 0
do something with 7 and 0
do something with 12 and 1

here is the basic logic . here you can get two variables $a and $b for every line. You can modify it as per your requirement

PHP Code:
while read line
do
a=`echo $line |awk -F: '{print  $1 }'`
b=`echo $line |awk -F: '{print  $2 }'`
a=`echo $a | tr -d '[:alpha:]'`
b=`echo $b | tr -d '[:alpha:]'`
echo "a=$a,b=$b"

done < $inputfilename
