[LINUX_Newbies] Re: Linux lost all sound

 

Inside alsamixer there is an auto-mute button. I reset that thing to disable auto-mute several times. Nothing happened. But when I was running a video that was silent because my sound is not working, disabling the auto-mute button suddenly worked fine. So, I think it's fixed, but I'll know for sure after a couple of reboots.

Is there a way to repair without reinstalling Linux and wiping out the hard drive?

Re: [LINUX_Newbies] Cant launch IRAF

 

Thanks, Scott. I have just been able to get on to the IRAF discussion
group. Maybe they can resolve this. I will submit your thought, without
your identity of course.

It seems to assume that you are using a C based shell, usually tcsh. That
has different syntax than bash. Depending upon your distribution, you
should be able to install csh or tcsh, then change to that shell to run it.

I don't know C shell at all, I would guess that the -e means exist, that
is, if this file exists, then source it.

[LINUX_Newbies] Cant launch IRAF

 

I installed a program called IRAF. It came back and said:
Congratulations! IRAF has been successfully installed on this system.

It then said:
To begin using IRAF you can simply type
% source ~/.login
% cl

However, when I executed the first line, i.e. source ~/.login, it came
back and said:
-bash: /home/stanlepast/.login: line 6: syntax error: unexpected end of
file.

The .login file has the following statement:
# add iraf setup commands
if ( -e /home/stanlepast/.iraf/setup.csh) then
source /home/stanlepast/.iraf/setup.csh
endif

The first line in .login is a blank line and so the sixth line is after
endif. What does this conditional statement do? It seems to be dependent
on what -e does.

I can alternate between two command prompts:
stanlepast@Sky:~$
and
stanlepast@sky:/$

The install program to install IRAF was run in a folder I created called
iraf.v2161 in the directory(right word?) controlled by the
stanlepast@Sky:/$ prompt, the one without the tilde. It lists the
iraf.v2161 folder when I enter the command 'ls'. The .iraf folder in the
file path in the .login file is in the stanlepast@Sky:~$ directory, the
one with the tilde. When I entered the command
source ~/.login
it was done in from the iraf.v2161 folder which is in the
stanlepast@Sky:/$ directory, the one without the tilde.

Should I should have installed IRAS in a folder in the stanlepast@Sky:~$
directory? Is that the reason I cannot get IRAF to run? I'm confused as
to which is the home directory, the one with the tilde or the one
without. The one with the tilde comes up when I boot the machine.
However, when I enter 'cd /' it is supposed to take me to the home
directory and it takes me to is the one without the tilde.

Re: [LINUX_Newbies] Changing file-folder colors and screen output

 

Scott,
I could see that the 'source' command is like an 'execute'. I know there
is a way to permanently mount the USB port (if port is the right word),
but after copying one file from the thumb drive to a file in linux I
have no immediate need to access it now. Remembering
mount /dev/sdb1 USB-1
is not possible and so I created a file with this line in it. I ran
source usbmount.stan
and it mounted the USB port. Very neat.

Re: [LINUX_Newbies] Changing file-folder colors and screen output

 

Thanks, Ken. There is a lot of detailed information in the link you
gave. Some day I might change the colors with the method they give. The
dark blue color for files is hard to see, but for now the following got
me back to where I was.
alias ls='ls --color'
source .bashrc
