Hey everyone, just entering the linux world, I need some help with a shell script i'm trying to write, the purpose is to check every 10 minutes what was the last time a certain file was modified, and if there is a connection to the server at this moment send an email with the date of the modification, if there is no connection, wait till there is - send the mail and wait another 10 minutes.
This is what I got:
it seems that the mail is sent 10 minutes after the connection was established (which is not what im trying to achieve)
any help and suggestions would be much appreciated!

If I want a script to sleep for less than a second, would I use a decimal? In other words, if I wanted my script to sleep for 1/4 of a second, would I say, SLEEP .25 ?? (5 Replies)
Does anyone know a way to sleep less than 1 second?
Sometimes when I write scripts that iterates a loop many times it would be
nice to slow things down, but sometimes 1 second is too much. (9 Replies)
This is a very crude attempt in Bash at something that I needed but didn't seem to find in the 'sleep' command. However, I would like to be able to do it without the need for the temp file. Please go easy on me if this is already possible in some other way:

LEARN ABOUT MINIX
mail
MAIL(1) General Commands Manual MAIL(1)NAME
mail - send and receive electronic mail
SYNOPSIS
mail [-dpqrv] [-f file] [user]
OPTIONS -d Force use of the shell variable MAILER
-f Use file instead of /usr/spool/mail/user as mailbox
-p Print all mail and then exit
-q Quit program if SIGINT received
-r Reverse print order, i.e., print oldest first
-v Verbose mode
EXAMPLES
mail ast # Send a message to ast
mail # Read your mail
DESCRIPTION
Mail is an extremely simple electronic mail program. It can be used to send or receive email on a single MINIX system, in which case it
functions as user agent and local delivery agent. If the flag MAILER is defined in mail.c, it can also call a transport agent to handle
remote mail as well. No such agent is supplied with MINIX.
When called by user with no arguments, it examines the mailbox /usr/spool/mail/user, prints one message (depending on the -r flag), and
waits for one of the following commands:
<newline> Go to the next message
- Print the previous message
!command Fork off a shell and execute command
CTRL-D Update the mailbox and quit (same as q)
d Delete the current message and go to the next one
q Update the mailbox and quit (same as CTRL-D)
p Print the current message again
s [file] Save message in the named file
x Exit without updating the mailbox
To send mail, the program is called with the name of the recipient as an
argument. The mail is sent, along with a postmark line containing the date.
For local delivery, a file named after the recipient in the directory
/usr/spool/mail must be writable.
If the directory /usr/spool/mail does not exist then the mail is
dumped on the console, so that system programs have a way to notify
a user on a system that does not have a mail spool.
