The Oracle Import process can be a good example of this. If you put the password
in the command, then you can see it when you use the "ps -ef | grep impdp".

Code:
impdp system/change_on_install ...

But if you use the echo command and pipe to the impdp command, then you won't
see the password when you do "ps -ef | grep impdp"

Code:
echo "system/change_on_install" | impdp  ...

Another option would be to put a delimited text file under the ~/.ssh directory.
You can then grep for the line that you want and use the cut command to grab
the password.

~/.ssh/pw
Code:
user:this_pwd
user1:this_pwd
user2:this_pwd
user3:this_pwd

You script that needs a password would have the following. Including the carrot
and colon will make sure that the line starts with the username and does not
accidentally pick up more than one line if you have similar usernames. You do
need to make sure that each username is unique in the file.
Code:
THIS_PWD=`grep "^user1:" | cut -d":" -f2`

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES

/etc/lirc/lircd.conf Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave- form details. DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics: "irsend: could not connect to socket" "irsend: Connection refused" (or "Permission denied"). SEE ALSO
The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory. lircd(8), mode2(1), smode2(1), xmode2(1), irrecord(1), irw(1), http://www.lirc.org. irsend 0.8.7pre1 May 2010 IRSEND(1)
