+Example 7 : Show the effect of using the execv series
+
+ ****************************************************************
+
+ Answer :
+
+ INSTRUCTIONS :
+
+ 1.These programs are part of systems programming PURELY in Unix and the commands have NO EQUIVALENT IN SCILAB
+
+ 2.However the .c files which are displayed here are also made into a seperate file.If you are a unix user then try compiling and
+ running the programme with gcc or cc compiler
+
+ 3.The outputs displayed here are just MOCK OUTPUTS which are DISPLAYED IN THE TEXTBOOK
+
+ 4.The inconvenience is regretted.
+.............Press [ENTER] to continue..... UNIX SHELL SIMULATOR(DEMO VERSION WITH PRELOADED COMMANDS)
+
+
+
+
+$ cat execv.c # to open the file emp.lst /* Program: execv.c -- Stuffs all command line arguments to an an array to be used with execv */
+
+#include <stdio.h>
+int main(int argc, char **argv) {
+ char *cmdargs[] = { "grep", "-i", "-n", "SUMIT", "/etc/passwd", NULL };
+ execv("/bin/grep", cmdargc); /* Execute another program*/
+ printf("execv error\n");
+}
+ $ cc execv.c $ a.out 15:sumit:x:102:10::/users1/home/staff/sumit:/usr/bin/bash
+
+
+$ exit #To exit the current simulation terminal and return to Scilab console
+
+........# (hit [ENTER] for result)
