So in my shell i execute:
{ while true; do echo string; sleep 1; done } | read line This waits one second and returns.
But
{ while true; do /bin/echo string; sleep 1; done } | read line continues to run, and doesn't stop until i kill it explicitly.
I have tried this in bash as well as zsh,... (2 Replies)
Bit of a weird one i suppose, i want to use an echo inside an echo... For example...
i have a script that i want to use to take users input and create another script. Inside this script it creates it also needs to use echos...
echo "echo "hello"" >$file
echo "echo "goodbye"" >$file

I want to print:
WELCOME TO MY WORLD
Where "WELCOME TO MY WORLD" will be in green (32) and the underline will be in yellow (33). How can i do the above using printf.
printf "`tput smul`\033
leaves both the text and the underline in green. (3 Replies)
echo `echo ` doesn't echoes anything. And it's logic. But
echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo"

Any way to get

This may be little confusing. I have Script1, which pulls data from the system and creates another script(lets say script2). While I run script1 I need to add printf/echo statements for script2, so that when I run script2 I see those statement.
eg: script1 765

Hello script guru's
as i write more and more code i always block at managing output... either writing to standard out, writing to files via std out (log, temp file, etc). Don't get me wrong 99% of the time it DOES the job but maybe there is more efficient.

Hello
I want to check whether certain arguments were passed to the script, and when those are, not doing a log entry.
If those arguments are not passed, always do a log entry (*new call*).
What currently i have is this:

Hello,
For some reason i dont remember, i currently believe (but beeing unsure) that printf is available on more diffrent systems (unix, bsd, linux, ??) than echo is.
Could someone please enlighten me, whether this is true or not?
Thank you

I just found pages about the diffrences of... (3 Replies)

IRSEND(1) FSF IRSEND(1)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

-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
irsend LIST DenonTuner ""
irsend SEND_ONCE DenonTuner PROG-SCAN
irsend SEND_ONCE OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
irsend SEND_STOP OnkyoAmpli VOL-DOWN
irsend SET_TRANSMITTERS 1
irsend SET_TRANSMITTERS 1 3 4
irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"
FILES
/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").
