Top Forums Shell Programming and Scripting Grep final set of parameters from fit.log gnuplot file Post 302789185 by Don Cragun on Wednesday 3rd of April 2013 08:38:07 AM

In your original problem, each entry in fit.txt contained 3 lines that contained the string +/- and the awk script I supplied plucked a value from each of these lines and added a new line after find the 3rd matched line in each entry:
Code:
awk -F' *=* +' '/[+]\/-/{printf "%s%s",$2,(++i%3)?" ":"\n"}' fit.txt

Now fit.txt contains entries each of which has 4 lines that contain the string +/- and guess what: the awk script:
Code:
awk -F' *=* +' '/[+]\/-/{printf "%s%s",$2,(++i%4)?" ":"\n"}' fit.txt

will do what you want. With you new fit.txt sample file, it produces:
Code:
0.498062 -0.00287463 -0.017153 -0.0145765
0.497897 -0.00459203 -0.0162969 -0.0139438
0.49692 -0.00889774 -0.0210222 -0.0182511

See the pattern? This pattern will work as long as the number of variables you're concerned about is a constant for any given input file. The logic would be more complex if the number of fields were to vary between entries.

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
