Hi

Can anyone does the scripting by using AWK? or other ways in shell scripting?

if I have input as "I love shell scripting ", I want to get output as "scripting shell love I "

Thanks

james

Code:

$ echo "I love shell scripting" | awk '{for (j=NF;j>0;j--) {printf "%s ", $j}}'
scripting shell love I

As long as we're calling external programs:

Code:

echo I love scripting | python -c "import sys; a = sys.stdin.readline().split(); a.reverse(); print ' '.join(a)"

Code:

echo I love scripting | ruby -e "puts STDIN.read.split.reverse.join(' ')"

I'm sure there's a one-liner in bash, but I got tired of salting/peppering and gave up :<
