Write a shell script (to run on the Bourne shell) that runs an infinite loop to check every 5 seconds to report on who logs into and who logs out of a UNIX system. Without loss of practical significance of this little utility, we can ignore multiple logins from the same user during a time period of... (1 Reply)
Hi,
I wanted to know if i can write a program using switches and signals, etc to trace execution of other unix program which calls c program internally.
If yes how? If not with signals and switches then are there any other methods apart from debugging with gdb/dbx. (3 Replies)
Hello Geniuses of the unix world. please help, stupid chemist. I have the following script that I need to create a file.

I have made use of 'valgrind' and -finstrument-functions compiler option for debugging / analyzing code. Both the options lets us know the line / file being executed to some extent.
Is there a generic way that lets program dump the file:line it is getting executed dumped to a log file during... (3 Replies)

Here's the assignment. I'll bold the parts that are rough for me. Unfortunately, that's quite a bit lol. The syntax is, of course, where my issues lie, for the most part.

cxref-cpp
cxref-cpp(1) General Commands Manual cxref-cpp(1)NAME
cxref-cpp - A modified C preprocessor to use with cxref.
SYNOPSIS
cxref-cpp ...
DESCRIPTION
To improve the output that is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
(named cxref-cpp).
This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler. In
a standard preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
not important.
With cxref-cpp, there are some features that are different to the standard GNU CPP:
Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include lines from the source
file. In version 2.8.0 and later this option is present.
Comments trailing a #include or a #define are not preserved by all versions of gcc even if the -C option is used. This is not
important while compiling, but is useful for documenting.
The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed. This
means that it includes the same default include directory paths and macro definitions. The file that contains these definitions is
called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by the -cxref-cpp-defines command line
option.
OPTIONS
The same as for gcc, apart from '-cxref-cpp-defines' described above.
