I am familiar with bash, but my works require csh. in my .cshrc, I created this alias:alias cd 'cd !:1; ls -l' It works very well except for one case: when I cd without any parameter:
cd In which case, I get the "Bad ! arg selector" error. How do I eliminate this error?
I got the following modprobe scripts modprobe -k -q streams what does the -k parameter mean?. is it exist in older modprobe? I don't see -k parameter in recent modprobe.

I am very new to shell scripting.How does one pass a command-line parameter to a shell script?for the below program
#/bin/bash
mount -t cifs -o user=ramkannan,password=Linux123@ //10.200.1.125/ramkannan /MT
cd /MT/test
date=`/bin/date "+\%Y-\%m-\%d-\%H-\%M-\%S"`
mysqldump -uroot -pram2@ employeedb > $date.sql
gzip $date.sql
I want to pass parameter for everything,i tried in google and did but iam getting error while passing parameter to all
#/bin/bash
mount -t cifs -o user=$1,password=$2 //10.200.1.125/ramkannan /MT
cd /MT/test
date=`/bin/date "+\%Y-\%m-\%d-\%H-\%M-\%S"`
mysqldump -uroot -pram2@ employeedb > $date.sql
gzip $date.sql
i was getting error while passing parameter to all.
This started happening about 2-3 weeks ago when i noticed our backups weren't running anymore. whenever i try to run ANY type of scp command I get the following error: warning: Unrecognized configuration parameter permitlocalcommand ssh: FATAL: Illegal -o parameter "PermitLocalCommand no" lost connection
I checked the /etc/ssh/ssh_config file and there was a command PermitLocalCommand commented out, but for testing I even totally removed that line and then in scp forced the use of that file via scp -F /etc/ssh/ssh_config ......
and I still get the same error. This command is nowhere is any of my ssh config files so im at a loss here on how im supposed to fix this!! I even checked my home directory for maybe a ssh config file that might be overridding the system config but nothing.
Whenever I login to a certain server using SSH I get a very long delay before a prompt appears. Everything I looked up on this issue says that it's a DNS issue and that I should disable reverse DNS lookups on the server.
But, the remote server is a shared webhosting server. I e-mailed the sysadmins but they say they have no DNS issue and that they won't change the server configuration. So, how can I fix this issue from my side (client side)? I have a static IP address and a hostname that points to it.
Every time kubuntu updates its headers/boot image I get another version on disk in /boot. These also show up in menu choices when I boot. I currently have 7 or 8 versions and would like to get down to three or four.
In the past I just deleted the files of related versions from /boot but is this the preferred method? Is there a better/safer way to get rid of old kernels?
I need a simplistic explanation of positional parameter. Have read all I can get my hands in, I kinds of understand to an extent, but I want to get. Full grasp of it. Oils like to know what is does, its functions, when to use it, and all its functions. Thanks in anticipation. Distro Red hat.

I recently enabled noapic on my laptop because it was experiencing strange input freezes on several distros that I tried.Ok, so it does not use the ioapics. My question is, what does this mean for the system? If it used apics before, what happens now? I am a freshly graduated computer science major, and I have worked with basics pics on projects before, but I am curious how this effects the running system.

I have a backup schedule running a full backup everyday. I'm using webmin to manage these backup now. The problem is when the dump command sends a prompt asking if we want to rewrite the tape, Webmin does not display this prompt and we end up having to terminate the backup -> erase the tape(which takes a long time) and then run the backup again.I was wondering if there is a technique that could be used to pass "Yes" as a parameter to the dump command, much like in windows? or if there is a more efficient way of getting this done.

I'm trying to install a Konica-Minolta M5670en printer. The printer is not found in the standard list so I got the ppd file(s) from Konica. There are two potential files: M5670opn.ppd and M5670PX.PPD. As downloaded, they are packaged as either a zip file or as a directory with the zip files unzipped.
Don't, laugh! This is the first time I've had to deal with a printer not already in the database. Which files do I need to use and where the heck do I copy them? When I run Yast printer->add the printer is found on the network and I try to specify the driver - but does it need the .zip file, the expanded directory, or what? So far, I'm not having much luck pointing to the downloaded files - either the zipped or unzipped versions. Yast copies the selected file to /usr/cups/model/download but then complains about file content and dies!

View 4 Replies View RelatedI've done the usual edit of /etc/sysctl.conf to include the parameter, but it just tosses errors. I haven't had to tune a kernel in a very long time, what's different about it nowadays (or have I simply forgotten how)?
edit: Added "kernel.semmni = 2048" to the tail of /etc/sysctl.conf and then ran "sysctl -p". End result is an unknown key error (apparently kernel.semmni isn't the valid name anymore?).
First off all, I'm booting from a large MEMDISK using PXE (900MB) . Due to our environment, I cannot decrease the size, nor move files to a nfs/iSCSI/... environment. Everything needs to be in that MEMDISK.
Now, when I try to run the OS, I get out of vmalloc space. How do I increase it to a number which allows such a large image to be mapped? I tried the parameter "vmalloc=1280M", but with that parameter, I don't get past the Booting the kernel screen.
Memory should not be an issue, since the machine(s) have at least 2GB RAM. (900MB MEMDISK + 256MB for other kernel stuff + 768MB for user stuff). The machine(s) have a Pentium 4 Extreme Edition processor, with hyperthreading and SSE2, but no EM64T.
How can I boot the system, and get past that message? Decreasing the MEMDISK size is not possible too. It is at the smallest we can get with our userland + kernel + modules.
I am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

View 11 Replies View RelatedI need to shift the positional parameters of a script inside a function, but any call to "shift 1" inside a function shifts only the parameters of that function. Is there some way of accomplishing that? I tried another approach using an alias. The problem is that I have to take the result of the alias. So I call in my script:
Code:
var=$(shiftalias)
At first time, it works correctly, but after that it does not shift the parameters anymore.
I have an issue that is fixed by changing the lpfc driver to run using MSI interrupts. This is done by adding "options lpfc lpfc_use_msi=2" /etc/modprobe.conf.local file.
Is there a way to make this change using kernel boot parameters?
