I have a program which I wish to modify. It used to be run from the command line, but now I wish to change this so it can be used as a function.
The program has complex argument processing so I want to pass my paramters to as if it were being called by the OS as a program.
I have tried to... (2 Replies)
I searched on the forums. No advises.
I am using a previous source code. I changed the main function main(int argc, char **argv) in a function misc(int argc, char **argv). How do you use the argc and argv parameters? This is how I am calling the function :
char param;
strcat(param,"wgrib ");... (4 Replies)
I have a script that asks a bunch of questions using the following method for input:
print "Name:";
while(<>){
chomp;
$name=$_;
}
So for example, if the questions asked for name, age, & color (in that order)... I want to be able to easily convert $ARGV into the input expected by... (2 Replies)
Hi C experts,
I have the following code for adding command line option for a program
int main (argc, argv)
int argc;
char *argv;
{
char *mem_type; //memory type
char *name; //name of the memory
int addr; //address bits
int data; ... (5 Replies)
this is in one of my scripts...
if ($#argv == 0) then
echo 'blah bla'
exit 0
endif
I want it to be something like this...
if ($#argv == 0 OR $argv >=3)
echo 'blah bla'
exit 0
endif
so when the arguments are none, or greater than three I want this "if then" to take over. how? I... (5 Replies)
Hello all,
Had a quick question:
In a typical csh script should inputting via stdin (i.e. set i = $< ) increase the value of $#argv ?
echo enter an value:
set val= "$<"
if($#argv == 0) then
echo No args
else
echo The arg is $argv
so if a value is inputted #argv... (1 Reply)

I'm working on my own pow function and I need to make a copy of *argv but
I think that I am having trouble with the size of *argv and the size of any array that I
make. The code below isn't working for me. and I want to accept any number no
matter the size with pow -f 2 2. I was working out... (16 Replies)
All of my machines (various open source derivatives on x86 and amd64) store argv above the stack (at a higher memory address). I am curious to learn if any systems store argv below the stack (at a lower memory address).
I am particularly interested in proprietary Unices, such as Solaris, HP-UX,... (9 Replies)

pkgsync
PKGSYNC(8) System Manager's Manual PKGSYNC(8)NAME
pkgsync - Automated package synchronization tool
SYNOPSIS
pkgsync
DESCRIPTION
pkgsync is a tool for keeping multiple machines reasonably similar and clean. Packages can either be in a `must be installed', `may be
installed' or `must not be installed' list (which is presumed to be distributed separately using a tool such as rdist or cfengine).
pkgsync will take care of meeting the demands put down in the lists, and then removing everything that is not in the `must' or `may' list
and is not necessary for their operations (as determined by aptitude).
OPTIONS -h, --help
Print a short help text and exit.
-s, --simulate
Do everything as usual, but put aptitude in simulation mode, causing it to never do any changes (except update and autoclean, which
should both be harmless) to your system. This is especially useful on a new system to make sure pkgsync behaves as expected.
Note that aptitude prints out its intended actions _before_ running the conflict resolver. If there's a conflict somewhere, chances
are that the results on your system will be different from what aptitude prints out.
-k, --keep-unused
Instruct aptitude to not remove cruft (ie. unused packages); this is morally equivalent to having an "*" entry in mayhave.
-d, --dpkg-glob
When encountering a wildcard pattern, pkgsync tries to `un-glob' it. Traditionally, this was done using dpkg -- however, in later
versions one can use aptitude instead. Using aptitude is a little slower, but the syntax is a lot more flexible, supporting regular
expressions and various searches on fields. Giving --dpkg-glob makes pkgsync use dpkg, which is not very useful except for backwards
compatibility.
-a, --aptitude-glob
Use aptitude's globbing instead of dpkg's globbing (see above). This option is the default.
