Sorry, but I don't believe that this line is syntactically correct (because of the "%" character) - but I could be wrong.
What Operating System and version you you have? There is much variation in the "ps" command.

Assuming that the syntax is correct on your system (which I do not believe), the "-o" parameter to "ps" allows you to display the parameters in any order.
We don't need "awk" to change the order of the fields. I note that "purdym" knows this.

Code:
ps -eo %cpu,pid,comm | sort -nr | head -10


My version of the HP-UX "Top 10 CPU users" includes:
Code:
UNIX95= ps -e -o pcpu -o ruser -o args|sort -nr|grep -v %CPU|head -10

This can equally be:
Code:
UNIX95= ps -e -o pcpu,ruser,args|sort -nr|grep -v %CPU|head -10


The "UNIX95" variable is specific to HP-UX and causes certain commands to behave with Berkeley unix syntax rather than Unix System V syntax. The manual suggests that the default "ps" syntax is "Posix" but that version is inferior to the Berkeley version.

NAME
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 0.9.0-pre1 October 2010 IRSEND(1)
