General :: Why Can't .cshrc File Be Sourced Automatically
Mar 22, 2010When I SSH to a certain Linux host, although my default shell is tcsh, the .cshrc file under my home directory is not sourced at all. I can't understand why this happens because from my understanding, if I'm using the tcsh, the .cshrc should be sourced anyway!
View 1 Replies View RelatedGeneral :: Clear Screen Command For BASH Shell
Jan 21, 2010I am unable to use clear or cls command on bash shell. I have recently installed Cygwin and am using that for practicing unix commands.
I see that I can use Ctrl + L to clear the screen. I created an alias in my .bashrc to do the same as
alias cls='^L'
This is how i defined other aliases e.g.
And they work. Hence I assume cls will work too but this is what I get when I try to give cls on command prompt. Am i missing something? Is there a way to do this?
Then someone suggested, You cannot alias keystrokes to commands or vice versa. You could just alias cls to an echo command: echo -en "x0c"
And I added the following to .bashrc,
Sourced the .bashrc file. No errors but cls still does not clear the screen. Infact when I typed the echo -en "x0c on command prompt as well, nothing happened. What does this command do?

Aug 13, 2009I want to use ssh to execute a command and to wait endlessly to log everything (in file) that comes as a stream of the connected server. But unfortunately, in the manual its written "If command is specified, it is executed on the remote host instead of a login shell"
So what happens is that when I specify my command:
ssh user@server "my_command"
It executed the command and the flow of execution returns to bash shell. So basically my session ends right after the command is executed. This happens only in case I specify command in the command line. If I login into ssh manually and then type "my_command", then the session doesn't end. I want the ssh not to exit, because after "my_command" executes, I want to capture everything in the session.

something like: -printfunction -printername < file*

Apr 13, 2010I'm relatively experienced with UNIX and Linux, but this has me thrown for quite a loop, and it seemed like such a simple question. How would I go about finding the newest file in a file system? I thought something like:
Code:
ls -ltr `find /usr -type f`
would work, but I seem to be exceeding the argument maximum for ls:
ksh: 0403-029 There is not enough memory available now
I thought something involving xargs might work, but I really suck with that command.
Ubuntu :: Bash Shell Implements Version Of The Command?
Mar 19, 2011I'm used to being able to put a script in ~/bin and having it overrule the system version of a command. However for "time" or "kill" since the bash shell implements a version of the command (i.e. /bin/ version is not used) doing this is not enough. How can I get the shell to run my own version instead of the version in the shell.I understand the implications of doing this. I know what I'm doing, I can always /bin/whatever if I want to get the old version (or just chmod -x ~/bin/whatever).

Programming :: Perl About System Command / Fails If The Standard Shell Is Dash And Not Bash?
Jun 30, 2011I am trying to fix a perl script, and I really suck at perl. But I think this problem will be easy for people who know it.
The problem is, I have an old setup script someone wrote many years ago. It fails if the standard shell is dash and not bash. The only way I've gotten it to work is to point /bin/sh to bash. I looked thru the script and it uses "system" many places, and I think that's the problem.
I searched for it and found this link:url
My plan is to include this function:
Code:
sub system_bash {
my @args = ( "bash", "-c", shift );
system(@args);
}
Then I could simply change all calls to system into system_bash and it should work?
The parameter to the system calls is usually some variable. What if the parameter is a list already? Do I need to test for it somehow, and if it's a list, prepend "bash" and "-c" to the list? How do I do that?
In the script there are lots of places like this:
my $error = system($cmd);
if ($error) {
die/warn "some error message";
}
Shouldn't there be a return in the system_bash function?

SUSE / Novell :: Bash File Corrupt, And Sh And Init Went Down With It?
May 23, 2010Yesterday afternoon, I was playing around with updating my system with RPMs from the openSUSE RPM Search. I had bash v 4.0.18 (I'm running a decaboot, the primary OS being openSUSE 11.2, where the issue is) and I installed a package that was bash 1.0.36. I restarted my Yakuake terminal to see the new bash. Immediately, I noticed the Yakuake terminal flashing rapidly, and the terminal wouldn't go down when I used the key that brings up and down, so I controlled-alt-escaped it and killed it off. Then I wondered if it was just me, so I hit ALT-F2 and logged in as root. It quickly said some symbol file (Something)_(Something)_REWRITE(maybe) then disappeared, giving my the login prompt. I though, well, OK maybe I have to restart it to get it to work. Init said "there is no more processes left on this runlevel" and I had to Power-Button it and reboot. When it rebooted, or tried to, I was greeted with "KERNEL-PANIC Tried to kill init"
I panicked with the kernel, and I went into my 11.3 Milestone 4 installation, tried to chroot it, but I received the same error as when I tried to log into root and was returned to my 11.3 session.
I later tried to do a mock update with the 11.2 DVD, and tried with the YaST package manager to downgrade BASH, but the RPM installation failed, even on good DVDs. I tried the rescue, but it said BASH wasn't a "critical file" while things I don't even use were checked (like openssh)
From 11.3, I tried linking sh from bash to ksh (Korne Shell). For all I know, it is just like bash. It didn't work. Same kernel error.
I relinked sh and bash together, and I am using SUSE 11.1 in the meantime, but does anybody know how to fix this without reinstalling my SUSE 11.2 completely.
Fedora :: Create A Shell Script File With Two Functions - Bash Scripting & /etc/bashrc
Oct 6, 2010how come I can create a shell script file with two functions, I can execute the file, but when running declare -f, the functions are not on memory, and when invoking the function bash returns invalid. In the other hand, I can copy & paste the two functions at the end of my /etc/bashrc file.... then I can called the function by name.... and the commands within that function run on my session. here is a print of all my bash packets:
