I have a router with linux firmware and attached to it a USB modem with which I can do both data and voice.Any other command send through echo method works ok. I was able to send SMS, edit phonebook and many many other stuff, but not make a call.So what is different from sending the call command within Minicom 2.5 and echo it?
View 1 RepliesI am writing an expect script that will automate flashing an embedded device through minicom using a serial connection and am running into problems sending backspaces.The script catches the configuration prompt on startup and can flash the device, but setting the MAC addresses in the fconfig are being problematic.For example, when I run the script, I can set the variables that are defaults by just pressing enter or enter new directives when prompted.. the problem arrises when I need to enter a new MAC address and there is already one set - I need to overwrite it somehow.
If I manually go through fconfig using minicom (minicom version 2.3 (compiled Dec 3 2008)), I can use backspace on my keyboard to remove the old MAC address and enter a new one - no problem.. but with expect.. I am having issues.I tried sending , ^H,10 177. These do not work. Minicom has BS set for the backspace key though.I tried setting it to DEL - no luck.On the other hand, I can send control-C with send "send 03".
I'm trying to use system to call echo and pass variables to it. That was a success. The problem is the variables inside the while-loop i wrote cannot be manipulated. what I'm doing wrong here? here's the code:
Code:
#include <iostream>
#include <stdlib.h>
#include <string>
#include <sstream>

I have to run "pppd call idea" command from root shell every time to connect to internet from mobile. Now I want a script so that I just run it to connect. Something like :
#!/bin/sh
echo "password" --stdin | su -
pppd call idea
But its showing error that "standard in must be a tty". Why is this. Using CentOS 5.5
In practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab
View 4 Replies View RelatedI am testing the serial ports on a Single Board Computer(SBC) running Linux kernel 2.6.29. I usually do this by connecting the serial port to another PC serial port, then doing "cat /dev/ttyS0" on PC and "echo hello > /dev/ttyS0" on the SBC. However in the current system, "echo hello > /dev/ttyS0" command does not return at all! Also no characters appear on the destination port. I am running the echo command as root. The system boot messages show that the serial port in indeed /dev/ttyS0.
View 2 Replies View RelatedIn a script, when I enter "echo $1" the first argument is outputted. When I enter:
a=1
echo "$$a"
The output is just "$1", not the first argument. If I enter:
a=1
b=$$a
echo $b
The output is still "$1" and not the first argument. How can I get echo to output the first argument without use "$1" directly?

command will just execute and exit with a status of "0" -"Every command returns an exit status (sometimes referred to as a return status ). A successful command returns a 0, while an unsuccessful one returns a non-zero value that usually may be interpreted as an error code. Well-behaved UNIX commands, programs, and utilities return a 0 exit code upon successful completion, though there are some exceptions."[URL]With the command . . .
Code:
# dosfsck -v /dev/sdb
it could be very helpful (and decide my next move) to see the exit code as 0, 1, or 2 . the man page suggests the command exit code will specify if the message I get - "Cluster size is zero" (I think it is a "1")is a recoverable or fixable error by the utility. or is non-recoverable - a pretty nifty feature if I understand this right. [URL] is there anything like this script COMMAND_LAST used in the following link. [URL] that can be entered in the terminal window after - or at end of - my dosfsck command or any command. just to see if it has a 0, 1, or 2 status ?
How can i enable caps lock by using echo command. I know that by using syntax echo -e "33[3q" this only turns the capslock led to glow. but the capslock is not working i.e. the words are typed in small case only.
Then by using xmodmap command i.e. syntax xmodmap -e "remove lock = Caps_Lock" or xmodmap -e "add lock =Caps_Lock" doesn't work. On running this it shows unable to display.
can anyone tell me how can one enable capslock by using echo command. ofcourse we can glow the led by using the echo command.
Its syntax is echo -e "33[3q"
On searching i found that by using $xmodmap -e "add lock=Caps_Lock" we can enable capslock. but its not working.
Can any body tell me where can i found the source code for echo command. so that i can download it such that it can help me for further studies on echo command
View 8 Replies View RelatedI logged into my Red Hat Enterprise Linux machine at work (use it for software development) and the primary GUI does not load. Instead, widgets appeared for xclock, xterm, and Firefox. In the terminal, I start typing in commands to try to figure out what's going on, but all commands are not found except pwd and echo. I 'echo $PATH' and that returns just an empty, blank line. 'echo $SHELL' lets me know I'm using cash.
The likely cause was my attempt to install Adobe Reader Firefox plugin yesterday. After it downloaded, I ran the binary but Firefox didn't seem to recognize that I had installed it, so I went into my .cshrc file and added the adobe folder to the path. That didn't seem to work, so I gave up, deleted the binary and the folder I installed to, and removed that directory from the path in the .cshrc file. This last thing (the export PATH line in that file) I'm certain is back exactly as it was before.
I have successfully added the /bin and /usr/bin back to the path from command line via
setenv PATH /usr/bin:/bin
but of course it doesn't stick after reboot nor does it magically load the primary GUI. I'd rather not go through the effort of creating a ticket for our company's Global Service Desk cuz there's no telling how long that could take to resolve. In the meantime, I can't do any programming.
I faced a issue with updating a file contents with echo command which fails with error as below:
echo "foo" > bar //to create a file named "bar"
echo "foobar" > bar //to edit its contents
The latter fails, it prompts "File exists" i.e.
~>echo "foo" > bar
~>echo "foobar" > bar
bar: File exists.
~>cat bar
foo
~>
What is the difference between
$echo cat
$cat echo

I came across an interesting site and I'm curious if I could make a private webpage to call some shell commands or just open a terminal.Yes, i know this could potentially be malicious and possibly illegal.

I'm using Linux 11.04 and just installed the most recent version of Postfix. I'm trying to send a simple email (through a relay) but when I run the command
sendmail davea@mydomain.com FROM: fromemail@gmail.com SUBJECT: hello world this is a test email .
It just hangs there. There is nothing in /var/log/mail.log or in any of its accompanying files.
I just have one question that is it possible to send same command at the same time to all windows in screen on Linux.

View 5 Replies View RelatedI'm installing a 10.04 server remotely - it's basically an RSYNC host for backups. I've got one minor issue - it's really more of an annoyance, but I would like to have it solved.When sending e-mails, the messages come in addressed to three destinations - when it's only supposed to be sent to one. What's worse is that the two additional addresses are based on the hostname of the machine.Let me explain: I use this command:Code:mail -s Testing email@somedomain.comI then compose the e-mail and send it. The mail arrive a few seconds later but addresed to the following:Code:from@hostname.domain.com;email@somedomain.com;hostname@hostname.domain.comThe "from@hostname.domain.com" has the actual word "from" in the address. I've installed many, many servers like this in the past and this is the first time that anything wonky with email has happened that I couldn't fix or explain. The machine is running postfix and I installed the bsd-mailx package to get the command line "mail" command (I used to install "mailx", but this seems to work just like the old package).
