Hi there,

I want to compare the output of two variables from two gawk command,
for example, v1=1221.73, v2=1441.33. I want to write a script or
anything that's conveient to do to compare these two variables and tell
which is bigger. I found that bash can only handle integers/characters.


My knowledge of script programming is quite limited. Could anyone give
me a little bit idea of what to do?

Thanks,
Maggie

Try this:

[mark@hotspur ~]$ echo '3.14159 2.71828 - p' | dc
..42331
[mark@hotspur ~]$ echo '2.71828 3.14159 - p' | dc
-.42331

dc is a RPN command line calculator, and is in the bc rpm. You can grep
the output for '-' and use the result of grep.
