This line of code is invalid
Code:
return system("/tmp/lab5.sh ", argv[count]);

The system() API takes one argument only. Man system for more information.

Hint - create a buffer using an array or malloc(). strcpy "/tmp/lab5.sh " to buffer. strcat argv[count] to the buffer. Use buffer as argument to system API.

NAME
PCRE - Perl-compatible regular expressions SYNOPSIS
#include <pcre.h> int pcre_copy_named_substring(const pcre *code, const char *subject, int *ovector, int stringcount, const char *stringname, char *buffer, int buffersize); int pcre16_copy_named_substring(const pcre16 *code, PCRE_SPTR16 subject, int *ovector, int stringcount, PCRE_SPTR16 stringname, PCRE_UCHAR16 *buffer, int buffersize); int pcre32_copy_named_substring(const pcre32 *code, PCRE_SPTR32 subject, int *ovector, int stringcount, PCRE_SPTR32 stringname, PCRE_UCHAR32 *buffer, int buffersize); DESCRIPTION
This is a convenience function for extracting a captured substring, identified by name, into a given buffer. The arguments are: code Pattern that was successfully matched subject Subject that has been successfully matched ovector Offset vector that pcre[16|32]_exec() used stringcount Value returned by pcre[16|32]_exec() stringname Name of the required substring buffer Buffer to receive the string buffersize Size of buffer The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string name is invalid. There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page. PCRE 8.30 24 June 2012 PCRE_COPY_NAMED_SUBSTRING(3)
