Loop for file existence
I wasn't sure if I should post it here of in the Shell Script category, but I figured it was definitely a newbie question.
I'm trying to write a script that will check for the existence of a specific file (or for any files within the directory) and then take specific actions. I've removed all the extra processing in the loop, comments, and variables. I'm just trying to get my basic loop to work.
I did check the FAQ's but I think this is even too basic a question for there. Anyone's assistance with this would be appreciated.
#!/bin/sh
if (test.dat exists in current directory)
then
echo "test.dat exists!" |mail
noone@domain.com
else
echo "test.dat does not exist!" |mail
noone@domain.com
fi

mailping
0.0.4
MAILPING-STORE(1) Mailping MAILPING-STORE(1)
NAME
mailping-store - store email from stdin to a mailping incoming maildir
SYNOPSIS
mailping-store
DESCRIPTION
mailping-store reads an email from standard input and writes it into a maildir chosen according to following logic:
1. If EXTENSION is not set, select Maildir.
2. If EXTENSION is set, ensure its value is safe to use, and select EXTENSION/incoming.
mailping-store is usually run from a .forward file, and thus the filenames above are relative to the home directory of the account in
question.
Normal use
Normally, mailping-store is used to ease the setup of new circuits to probe from mailping-cron. This is done with a system account mailping
using <mailping@yourhost.example.com> as the from address, and <mailping+circuitname@yourhost.example.com> (or some remote address aliased
to that) as the to address. In fact, these are the default values for from and to, so you can just skip creating those configuration files.
This allows adding new test circuits without any changes to the email configuration.
FILES
/var/lib/mailping/state/circuit/incoming
Maildir to store the email to.
/var/lib/mailping/state/Maildir/
Maildir to store the email to, if no extension was given.
ENVIRONMENT
MAILPING_STATEDIR
Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories
named after the circuit name. Default: /var/lib/mailping
EXTENSION
Name of the current circuit to store the mail for.
