For some reason, the array paths is getting destroyed after alias does its job. Atleast thats what I observed.. My alias code is something like this:

Code:

if(aliasoption == 1)  {
            strcpy(buff, "csh -c \"alias ");
            strcat(buff, command);
            strcat(buff, wordclose);
            /*printf("%s",final);*/
            fp = popen(buff,"r");
            if(fp == NULL)
            {
                  printf("Handle Error");
            }
            /*else printf("Opened\n");
            printf("You asked for an alias\n");*/
            printf("alias %s= ",command);
            while(fgets(buff,sizeof(buff),fp) != NULL)
                  printf("%s",buff);
            pclose(fp);
            printf("\nNew Line");
        }

Edit: I tried defining paths[] as a Global Variable but no luck...

NAME

       profil - execution time profile

SYNOPSIS

DESCRIPTION

       controls profiling, by which the system maintains estimates of the amount of time the calling program spends executing at various places in
       its address space.

       The buff argument must point to an area of memory whose length (in bytes) is given by bufsiz.  When profiling is on, the process's  program
       counter	(pc) is examined each clock tick times per second), offset is subtracted from the pc value, and the result is multiplied by scale.
       If the resulting number corresponds to an element inside the array of to which buff points, that element is incremented.

       The number of samples per second for a given implementation is given by which is defined in

       The scale is interpreted as an unsigned, sixteen bit, fixed-point fraction with binary point at the left: 0177777 (octal) gives	a  one-to-
       one  mapping  of  pc's to words in buff; 077777 (octal) maps each pair of instruction words together.  02(octal) maps all instructions onto
       the beginning of buff (producing a non-interrupting core clock).

       Profiling is turned off by giving a scale of 0 or 1.  It is rendered ineffective by giving a bufsiz of 0.  Profiling is turned off when one
       of  the	functions  is executed, but remains on in child and parent both after a Profiling is turned off if an update in buff would cause a
       memory fault.

RETURN VALUE

       No value is returned.
