Agree to that, But would more keen on bash scripting for learning purpose
I have already stated that bash ONLY has integer maths, so let's see its limitations:
(<CR> is the ENTER key.)
Try this example in bash: echo $(( 3/4 ))<CR> and see the result as 0, ZERO, NOT 0.75!
Now try this in bash: NUM=$(( 3/4 )); if [ "${NUM}" -le "0.75" ]; then echo "True!"; else echo "False!"; fi<CR>
Do you see where the next step goes?
Utilities are needed for any floating point requirements.
Now try this utility, which I guess you already have: NUM=$( python -c "print(3.0/4.0)" ); echo "${NUM}"<CR> ; yes this works on Python 2.x.x and 3.x.x.
You now have your floating point number - BUT - how do you compare knowing there is an error report saying: -bash: [: 0.75: integer expression expected ...
Now ksh is a different animal, similar to bash but has full floating point and integer maths capability and with a little work can create something like this little beauty: DFT using pure ksh ONLY!

Reason: Correct error report...
Here you go in bash, this REQUIRES integer number input for salary:
You will have to work out how to use floating point for input, it would be tedious but a draft so far...

Thanks a lot for your inputs, I would like to sort into descending order based one Avg Q while displaying the table
While using above code i am not able to sort based on Avg Q. Instead the header is also getting sorted
You wanted the python code in bash so don't run before you can walk!
The code, (#11), CAN be improved, it also has no error detection nor reporting, it has no means of going over a persons wrongly inputted data and it WILL overwrite the file on every (re)run.
I left those those anomalies out for you to to learn by working them out.
And line 3 of your python code does NOT do what you expect: av1 = float(sum / 4)
As your example always shows integer values for q1 to q4 the let's see what happens...
As you can see, the float is a conversion of integer division.
Either that is a bug or q1 to q4 MUST be, for example, sum = 5.0+6.0+7.0+7.0 to arrive at 6.25...

If there are 2 records for an Employee, How can I choose the one with eff_status = ‘Active' and ignore the eff_status ='Terminated'. if there is only one record, then just write that record regardless of the eff_status.

About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix.

Hi ,
this is the first time i use bc to calculate and i would have decimal result , i use the following :
toto=400;scale=1 echo $toto / 1000|bc
scale to adjust the numbers after the command would have in this case 0.4 as result and i wonder why i have always 0 as result.
Somebody can... (2 Replies)
