Hello,

Following may help in same.
Code:
awk '{for(i=1;i<=NF;i++){{if(i%2 != 0){print "for pa in " $i ORS "do" ORS "blah blah" ORS "done\n"} else {print "for pb in " $i ORS "do" ORS "blah blah" ORS "done\n"}}}}' Input_file

Output will be as follows.
Code:
for pa in 14.5
do
blah blah
done
 
for pb in 16.7
do
blah blah
done
 
for pa in 7.8
do
blah blah
done
 
for pb in 9.5
do
blah blah
done
 
for pa in 5.6
do
blah blah
done
 
for pb in 3.6
do
blah blah
done
 
for pa in etc
do
blah blah
done
 
for pb in etc
do
blah blah
done

EDIT: Adding more solutions for same.

Code:
awk '{for(i=1;i<=NF;i++){V=i%2 != 0?(V="pa "):(V="pb "); {print "for " V "in " $i ORS "do" ORS "blah blah" ORS "done\n"}}}'  Input_file
OR
awk '{for(i=1;i<=NF;i++){{if(i%2 != 0){V="pa "} else {V="pb "}; print "for " V "in " $i ORS "do" ORS "blah blah" ORS "done\n"}}}' Input_file

Thanks,
R. Singh
