Question
To interactively get input variable through awk programming
How do I input a variable interactively through awk programming in a shell script
Just to brief more on this question...
I was just trying to find the size of the files that is created or modified on January
my script goes like this
ls -ltr|awk '{$6="Jan" sum+=$5}'
Now I thought of entering the month value interactively instead of setting it to "Jan". Is that possible???

Don't quite understand what you want, as awk works on files, but if you mean say, get awk to read for standard input and out put the awk formatted text to a file, then something like the following should work (to reverse two strings)
awk '{print $2" "$1}' - >outfile (to file outfile)
awk '{print $2" "$1}' - (to screen)
you can then input 2 strings, press return, then CTRL D to exit.
If that's not exactly what you want, please gives some more details.
