Try this if you don't want to change your c program

#!/usr/bin/perl -w

my $timeout = 5; # 5 sec timeout

eval {
local $SIG{ALRM} = sub { die "alarm\n" };
alarm $timeout;
qx(./mah.ksh);
alarm 0;
};

if ($@) {
die unless $@ eq "alarm\n";
print "timeout\n";
qx(ps -ef | grep mah.ksh | egrep -v " grep | vi | more | cat | pg | egrep " | awk '{print \$2}' | xargs kill );
}
else {
print "no timeout \n";
}

replace mah.ksh with your c program name.

zgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
