Full Discussion: Set +A usage
Top Forums Shell Programming and Scripting Set +A usage Post 302341465 by kshji on Thursday 6th of August 2009 03:51:44 AM

set -A or set +A works only in ksh, not in bash.
Code:
set -A arrayname list of values

Add echo before cmdline = see the result = howto shell expand commandline = after
that has done command.

You can make the list so many ways
- using some variable like $*
- cmd like $(who)
- give valuelist val1 val2 val3 "val4 is longer" val5


Code:
# number of elements in array
${#array[*]}

# all elements
${array[*]}

1st element index is 0
Code:
echo "1st:${array[0]}"
#
last=${#array[*]}
((last -= 1 ))
echo "last:${array[$last]}"

And last, shift array - remove 1st element
Code:
set -A array "${array[@]:1}"

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
