I am complete noob in this and I have to write a program which:
Calculates the modulus of two numbers which the user enters with keyboard. Number interval 1-9. These two numbers that were entered and modulus which was calculated are stored in a separate file.
When the modulus equals 0, two previously entered numbers along the the calculated modulus (which is zero) are printed on the screen to the user.
The only constraint about the code - no conditionals should be used writing the program (if, while, etc.).
Please help me to do this. Cannot think of it myself.
I know little and we just started learning bash scripting so it should be simple I guess.
I tried to play with "sed" "grep" "read" commands without much success. Cannot fullfill all the requirements.
Please help. This is a very brief example what I have managed to do. :/

else
LIBS =
endif
Its amazing that this works when invoked... (4 Replies)

Hi there, I have a table that stores multiple records for many different servers, each of which is timestamped ... I wanted to write a query that would enable me to only output the "latest" record (based on timestamp) for each "unique" server. So for example my main table looks like this

Hi was wonderring about the syntax for the following peice of code:
while ] ; do
This is apparently incorrect. I want the loop to continue WHILE $life is not equal to zero or $mask is not equal to $word. Should ONE of these conditions fail to be met, loop should break out. Any ideas? ... (8 Replies)

Pardon the pseudo code below, but I'm wondering how I would do something along the lines of this...
#!/bin/sh
excludeList="A B"
theItem="C"
if
then
echo $theItem
fi
I know I could loop through the array and check against each value, but was wondering if there was an alternate way... (1 Reply)
Yet another question. I want to make something like this:
if ||&&
then

fi
but that apparently is not right. I want either the first condition to be true OR the second AND third conditions to be true for the "then" to be processed. How can I do this? (1 Reply)
