Shell Programming and Scripting

Hi,

I need to compare and get an output for values greater than "X10" (values contain both characters and numbers) using if loop...

FOR EG:

I want to export values greater than X10, i.e., in-case if the value is X11 and greater than the "if" part to be executed if the value is X9 and less than that "else" part to be executed.

I tried the below code, when i passes A as X9 or X11 also the "ELSE" part is only executed

Code:

if [ $A -gt X10 ];then
    export "$A is correct"
else
    export "$A is incorrect"
fi

Can any one correct me where i went wrong???

Thanks
Shiva

How to use code tags

Hi,

when comparing string (sorting) order replace the if..else conditional statement with:

Code:

[[ "$A" > "X10" ]] && echo "$A is correct" || echo "$A is incorrect"

Which basically means:
if the test inside the double square brackets returns true, display "$A is correct" else display "$A is incorrect".

You can find more about [[ ]] tests in bash man page, section 'Compound Commands'.

Keep in mind that you are comparing strings, so "X9" is actually > (that is, greater than) "X10".
