Actually in my case always there are always some server.log file present with timestamp. So I would always like to check the if statement with timestamp.
I tried after your suggestion like the below:
This is also failed to find the files so the else block is executing.
Hi,
I have a shell script Scp_1.sh for which I have to pass 2 arguments to run.
I have another script Scp_2.sh which in turns calls script Scp_1.sh inside.
How do I make Scp_1.sh script to read arguments automatically from a file, while running Scp_2.sh?

pmgetarchiveend
PMGETARCHIVEEND(3) Library Functions Manual PMGETARCHIVEEND(3)NAME
pmGetArchiveEnd - locate logical end of file for an archive log
C SYNOPSIS
#include <pcp/pmapi.h>
int pmGetArchiveEnd(struct timeval *tvp);
cc ... -lpcp
DESCRIPTION
Assuming the current PMAPI context is associated with an archive log, pmGetArchiveEnd will attempt to find the logical end of file (after
the last complete record in the archive), and return the last recorded timestamp via tvp. This timestamp may be passed to pmSetMode(3) to
reliably position the context at the last valid log record, e.g. in preparation for subsequent reading in reverse chronological order.
For archive logs that are not concurrently being written, the physical end of file and the logical end of file are co-incident. However if
an archive log is being written by pmlogger(1) at the same time an application is trying to read the archive, the logical end of file may
be before the physical end of file due to write buffering that is not aligned with the logical record boundaries.
pmGetArchiveEnd returns an error less than zero if the context is neither valid, nor associated with an archive, or the archive is seri-
ously corrupted. Otherwise, the return value is 0 if there has been no change of state since the last call, or 1 if the logical end of
file has advanced since the last call.
In the absence of an error, the result returned via tvp is well-defined.
pmGetArchiveEnd preserves the positioning state of the log file prior to this function call.
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura-
tion file, as described in pcp.conf(5). Values for these variables may be obtained programmatically using the pmGetConfig(3) function.

DIAGNOSTICS
PM_ERR_NOCONTEXT
the current PMAPI context is either invalid, or not associated with an archive log
PM_ERR_LOGREC
the archive is sufficiently damaged, that not a single valid record can be found
