Still has not validated my two test questions:
I may reverse-engineer and recreate the OTDB database structure and create our own database for this, so we can submit and build our own questions and answers without waiting for that site to validate and approve.
Hello guys!
Can say me anybody about operatios with unix, I don't to make operations, only inside in a variable, like this
#y=4
#x=2
#let z=$y-$x
#echo $z
# 2
but I can't to make mathematical operations with decimal like this
#y=3.2
#x=1.5
#let z=$y-$x
#echo $z
# 3

Hello all!
I used to use expr for doing simple mathematics, but has a main advantage and a main disadvantage:
The advantage is that it can take variables for numbers
(e.g.{1}: echo "Give me first"
read lol
echo "Give other"
read lil
sum=`expr $lol + $lil`
echo "The sum of $lol and $lil =... (5 Replies)
Hi,
I haven't posted on the forums for a while now, I tried to find the most appropriate section for this post, but if this is in the wrong section please forgive me.

The UNIX and Linux Forums now has over 1000 TRUE / FALSE computer science and computer related trivia question in our database. These questions are of relatively high quality (compared to similar sites on the web) and are fun (according to feedback by users). In the first week during the... (1 Reply)

Only a few days after I coded this new feature from scratch, we are seeing over 3000 entries in the database from members (mostly guests) playing CS trivia.
I have spend a lot of time coding this (from scratch) and testing the API. From the logs, it seems to have an API bug which appears... (31 Replies)

TEST(1) General Commands Manual TEST(1)NAME
test - condition evaluation utility
SYNOPSIS
test expression
DESCRIPTION
The test utility evaluates the expression and, if it evaluates to true, returns a zero (true) exit status; otherwise it returns 1 (false).
If there is no expression, test also returns 1 (false).
All operators and flags are separate arguments to the test utility.
The following primaries are used to construct expression:
-b file
True if file exists and is a block special file.
-c file
True if file exists and is a character special file.
-d file
True if file exists and is a directory.
-e file
True if file exists (regardless of type).
-f file
True if file exists and is a regular file.
-g file
True if file exists and its set group ID flag is set.
-h file
True if file exists and is a symbolic link.
-n string
True if the length of string is nonzero.
-p file
True if file is a named pipe
-r file
True if file exists and is readable.
-s file
True if file exists and has a size greater than zero.
-t [file_descriptor]
True if the file whose file descriptor number is file_descriptor (default 1) is open and is associated with a terminal.
-u file
True if file exists and its set user ID flag is set.
-w file
True if file exists and is writable. True indicates only that the write flag is on. The file is not writable on a read-only file
system even if this test indicates true.
-x file
True if file exists and is executable. True indicates only that the execute flag is on. If file is a directory, true indicates
that file can be searched.
-z string
True if the length of string is zero.
string
True if string is not the null string.
s1 = s2
True if the strings s1 and s2 are identical.
s1 != s2
True if the strings s1 and s2 are not identical.
n1 -eq n2
True if the integers n1 and n2 are algebraically equal.
n1 -ne n2
True if the integers n1 and n2 are not algebraically equal.
n1 -gt n2
True if the integer n1 is algebraically greater than the integer n2 .
n1 -ge n2
True if the integer n1 is algebraically greater than or equal to the integer n2 .
n1 -lt n2
True if the integer n1 is algebraically less than the integer n2 .
n1 -le n2
True if the integer n1 is algebraically less than or equal to the integer n2 .
These primaries can be combined with the following operators:
! expression
True if expression is false.
expression1 -a expression2
True if both expression1 and expression2 are true.
expression1 -o expression2
True if either expression1 or expression2 are true.
(expression)
True if expression is true.
The
-a operator has higher precedence than the -o operator.
GRAMMAR AMBIGUITY
The test grammar is inherently ambiguous. In order to assure a degree of consistency, the cases described in the IEEE Std 1003.2
("POSIX"), section D11.2/4.62.4, standard are evaluated consistently according to the rules specified in the standards document. All other
cases are subject to the ambiguity in the command semantics.
RETURN VALUES
The test utility exits with one of the following values:
0 expression evaluated to true.
1 expression evaluated to false or expression was missing.
>1 An error occurred.
BUGS
Named pipes are not implemented in 2.11BSD.
STANDARDS
The test function is expected to be IEEE Std 1003.2 ("POSIX") compatible.
