You don't need to run ID 5 times to get 5 different pieces of data from it. Run it once, get all the data from it the first time.
You are using single quotes, which take their contents literally, where you need backticks, which run their contents. But you don't even need that statement.
You don't need to do \( all the time, just use quotes. Variables will expand inside double-quotes, even, so you don't need to end the quotes to use a variable.
Whenever you're doing if [ `... | wc -l` -gt somevalue ] to check something, you've probably missed a simpler way. Here, since I've overwritten the $1 ... arguments, I use the special "$#" variable, the number of arguments instead.

Hi
what's the correct way of writing if
1)if "$time_diff" -gt 5
then
echo "killing hung process \n"
fi
2)if test $time_diff -gt 5
then
echo "killing hung process \n"
fi
where -time_diff=$(($Sam - $current_min))
and current_min=`date +%M`
infact both are giving Syntax... (1 Reply)
This is the code:

I read a command on every loop an execute it.
I check if the string equals the word stop to end the loop,but it say that I gave too many arguments to test.
For example echo hello.

I'm calling the following if-else from nawk. But I keep getting an error at the "else". I've tried putting more brackets and ; but still I get complaints about the "else".
Any ideas ?

atf-test-program
ATF-TEST-PROGRAM(1) BSD General Commands Manual ATF-TEST-PROGRAM(1)NAME
atf-test-program -- common interface to ATF test programs
SYNOPSIS
atf-test-program [-r resfile] [-s srcdir] [-v var1=value1 [.. -v varN=valueN]] test_case
atf-test-program -l
DESCRIPTION
Test programs written using the ATF libraries all share a common user interface, which is what this manual page describes. NOTE: There is no
binary known as atf-test-program; what is described in this manual page is the command-line interface exposed by the atf-c, atf-c++ and
atf-sh bindings.
In the first synopsis form, the test program will execute the provided test case and print its results to the standard output, unless other-
wise stated by the -r flag. Optionally, the test case name can be suffixed by ':cleanup', in which case the cleanup routine of the test case
will be executed instead of the test case body; see atf-test-case(4). Note that the test case is executed without isolation, so it can and
probably will create and modify files in the current directory. To execute test cases in a controller manner, you need a runtime engine that
understands the ATF interface. The recommended runtime engine is kyua(1). You should only execute test cases by hand for debugging pur-
poses.
In the second synopsis form, the test program will list all available test cases alongside their meta-data properties in a format that is
machine parseable. This list is processed by kyua(1) to know how to execute the test cases of a given test program.
The following options are available:
-l Lists available test cases alongside a brief description for each of them.
-r resfile Specifies the file that will receive the test case result. If not specified, the test case prints its results to stdout. If
the result of a test case needs to be parsed by another program, you must use this option to redirect the result to a file
and then read the resulting file from the other program. Note: do not try to process the stdout of the test case because
your program may break in the future.
-s srcdir The path to the directory where the test program is located. This is needed in all cases, except when the test program is
being executed from the current directory. The test program will use this path to locate any helper data files or utilities.
-v var=value Sets the configuration variable var to the value value.
