I just needed some help with running the bash shell. I think I might have accidentally corrupted a file when I was looking through the /bin dir. Anyways, whenever I login to my server via SSH I get the following output:
View 1 RepliesYesterday 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.
I want to change my default shell to tcsh. I used
Code:
usermod -s /bin/tcsh username
command as given at url
But if I open a new shell, it is still a bash shell.
How do I make my default shell as tcsh?
Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
today I upgraded (yum update) one of my Dell Poweredge Server from 5.2 to 5.3. After rebooting the system first seems to start normal but then the following Error Messages appear:
Apr 5 14:28:26 srv_1 kernel: I/O error in filesystem ("dm-0") meta-data dev dm-0 block 0x668000008 ("xfs_trans_read_buf") error 5 buf count 4096
Apr 5 14:28:26 srv_1 kernel: attempt to access beyond end of device
Apr 5 14:28:26 srv_1 kernel: dm-0: rw=0, want=27514634256, limitfs]
[code]....
Booting with a rescue disk and doing a xfs_repair solves the file system Problems but moved a lot of files ( at least /usr/bin and /usr/lib completly) to "lost+found"... I tried the update with a spare 5.2 Server (different Hardware), and ended up with exactly the
same effect and error message. Both systems are running XFS as root File system on an LVM Disk.
Does it use Bash or some other shell?

One of the useful command I used frequently is foreach.> foreach a (`cat list`)>> echo $a need to use bash shell now instead, and realized that I can't use foreach anymore. The command is not found. Does anyone knows if there is similar command / function in bash shell?
View 9 Replies View RelatedSo I open firefox from my bash shell with:
Code:
firefox google.ca
it opens firefox, I can browse, etc.
Now if I alt-tab back into my shell, i can't enter any commands in the shell.
I know that i can do this if I close firefox, but I want to keep working in my shell with firefox still open.
Is this possible?
I use ":!shell_command<enter>" OR ":sh<enter>" in gvim to execute shell commands or to get a shell. But I am getting an 'sh' shell. Is there a way to get the 'bash' or 'csh' shell from within gvim?

i've finally got a NIX environment...yipee! Installed opensuse 11.2 in a dual boot with windoze with no problem whatsoever. unfortunately, my NIX skills are sadly dated or maybe things have changed or both. in any case, i have a rather trivial problem that i have not been able to figure out.
i go to gnome terminal to get to the bash shell, no problem except when i do things like cat, less and so on. the commands do what they do then when done the last line output is "some text" and "(END)" - at the completion of the command it does not return to the bash shell. i've tried ctrl-everything, enter, escape, actually all keystrokes i can think of to get back to the bash shell...no luck. man and docs have not been helpful or i simply missed the answer (i'm a little saturated at this point).the only thing i've been able to do to solve my dilema is close the terminal an start a new instance, not elegant but works.
I changed the default SUSE prompt setting by modifying the shell variable PS1 to display the following information:
u : the username of the current user
h : the hostname up to the first '.'
w : the current working directory, with $HOME abbreviated with a tilde
I used export command to setup a new shell prompt:
export PS1="[u@h: w]$ " To add colors to the shell prompt and make a regular user prompt blue I used the following command syntax:export PS1="e[0;34m[u@h: w]$ e[m "

I am wondering if there is an easier way? I suspect, a custom script is in order, but perhaps someone else has done something similar before.

In linux how do I to get the ascii decimal/hex/oct code from a char or a ascii char from a decimal/hex/oct code. I see from the gnu sed user manual that I can use the d# o# x# to specify a character but I am not sure how to use that. If some one has a better way to get the the ` and ' chars through I want to sed with the backtick '`' character and ''' single quote character.
sed '/`/p'
these don't work

I would like to create some aliases for bash shell. On other Unix/Linux machines I have done this using the alias command like this: alias rm rm -i
When I type that into a terminal on Ubuntu, it looks like alias is not installed. I get this:
bash: alias: rm: not found
bash: alias: rm: not found
bash: alias: -i: not found
I tried adding the alias to .bashrc instead, but then I get the same error message every time I start terminal. Just for fun I tried apt-get install alias, just to see what would happen, and it installed something called libperl-alias instead, and alias still doesn't work.
Whats the difference, and when do you use which?
View 2 Replies View RelatedI am working on a simple script that should take two command line arguments, a [number] and a [name]. The first thing the script should do is check to make sure that no more and no less than two command line arguments have been entered when calling the script - an error message should be delivered if the condition is not true.
If two args have been entered, then the message 'processing "scriptname"' should appear, where scriptname is the name of the script being called. The script should then write to the screen "Hi [name]!", and should write this phrase [number] of times. For example, the command $ myscript 2 joe would produce the output: I have read the manual many times looking for examples, and I am very close by virtue of my own efforts. Further, I have searched these forums and others for good examples, which have also gotten me very close. Still my script is not completing the objective, and I am wondering if someone could point me in the right direction. Script:
