I need to take the latest month hdfs folder while passing date as parameter.
For eg . if i pass as Feb month i.e. 20190201(YYYYMMDD), then i need the output as 2019_01_31 by reading the above hdfs direcotories. I also need to check if there are any data then get the dte as 2019_01_31. For eg /user/home/dte=2019_01_31/part_1 should be more than 0 KB file
Dear All,
I am going to examine SA202 but I got SA-202-S10 revision A.1 so it might be out of date.
Who has "Solaris 10 Advanced System Administration(SA-202-S10)" latest revision document? Could you share it ?
Thank you in advance (2 Replies)

system
SYSTEM(3) BSD Library Functions Manual SYSTEM(3)NAME
system -- pass a command to the shell
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
int
system(const char *command);
DESCRIPTION
The system() function hands the argument command to the command interpreter sh(1). The calling process waits for the shell to finish execut-
ing the command, ignoring SIGINT and SIGQUIT, and blocking SIGCHLD.
If command is a NULL pointer, system() will return non-zero if the command interpreter sh(1) is available, and zero if it is not.
RETURN VALUES
The system() function returns the exit status of the shell as returned by waitpid(2), or -1 if an error occurred when invoking fork(2) or
waitpid(2). A return value of 127 means the execution of the shell failed.
SEE ALSO sh(1), execve(2), fork(2), waitpid(2), popen(3)STANDARDS
The system() function conforms to ISO/IEC 9899:1990 (``ISO C90'') and is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
