I am trying to find the difference in days between 2 dates.
I have to extract the 1st date from a filename, which i did using the awk command.
I have to compare this date to today's date and if the difference is greater than 30 days, do something, else do something else.
This is what i wrote
The result that I got was
The difference between the dates is not 105 days, but 34 days.
What am i doing wrong - I am pretty new to Shell programming and am learning through this site.

# Set Prompt
typeset -RZ2 _x1 _x2 _x3
let SECONDS=$(date '+3600*%H+60*%M+%S')... (5 Replies)

Hi all,
Sorry for the title because I didn't find a proper name for it. My question is about POSIX functions, such as timer_create(), mq_open() and pthread_create().
void test_queue()

Hi,
So I have a very simple script which loops over 5 times and prints the iterator value.
#!/bin/sh
START=1
END=5
for i in $(eval echo "{$START..$END}")
do
echo "$i"
done
If I save this script in a .sh file and run it in the terminal, the output I get is

linux::distribution
Linux::Distribution(3pm) User Contributed Perl Documentation Linux::Distribution(3pm)NAME
Linux::Distribution - Perl extension to detect on which Linux distribution we are running.
SYNOPSIS
use Linux::Distribution qw(distribution_name distribution_version);
if(my $distro = distribution_name) {
my $version = distribution_version();
print "you are running $distro, version $version
";
} else {
print "distribution unknown
";
}
Or else do it OO:
use Linux::Distribution qw(distribution_name distribution_version);
my $linux = Linux::Distribution->new;
if(my $distro = $linux->distribution_name()) {
my $version = $linux->distribution_version();
print "you are running $distro, version $version
";
} else {
print "distribution unknown
";
}
DESCRIPTION
This is a simple module that tries to guess on what linux distribution we are running by looking for release's files in /etc. It now looks
for 'lsb-release' first as that should be the most correct and adds ubuntu support. Secondly, it will look for the distro specific files.
It currently recognizes slackware, debian, suse, fedora, redhat, turbolinux, yellowdog, knoppix, mandrake, conectiva, immunix, tinysofa,
va-linux, trustix, adamantix, yoper, arch-linux, libranet, gentoo, ubuntu, scientific, oracle enterprise linux and redflag.
It has function to get the version for debian, suse, fedora, redhat, gentoo, slackware, scientific, oracle enterprise linux, redflag and
ubuntu(lsb). People running unsupported distro's are greatly encouraged to submit patches :-)
EXPORT
None by default.
TODO
Add the capability of recognize the version of the distribution for all recognized distributions.
