Top Forums Shell Programming and Scripting The scope of the shell/perl script is to read the input text file. Validate the expiry date of each Post 302516013 by Skrynesaver on Thursday 21st of April 2011 11:06:25 AM

To read throug the file a line at a time:
Code:
#!/usr/bin/perl
open(my $cert_file, '<' , 'PATH_TO_FILE');
while(<$cert_file>){

To get the current time
Code:
@now=localtime(time); # see time_t structures to see how this can be turned into your desired format.

To extract the date (4th field) from the record
Code:
my ($host, $cert,$start,$end)=split / | /, $record);

Try stringing that lot together and come back with any issues you are having

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
