There are weird commas after the real-name parameter of some lines in my /etc/password file.
kye:x:1000:100:Kye,,,:/home/kye:/bin/bash
What gives? Why are they there? Can I remove them?
Using sed, I am trying to append four commas ',,,,' at the end of lines containing the pattern 'Response' in a text file with lines such as these:

When I ls -l /etc/passwd, -rw-r--r-- 1 root root /etc/passwd When I login as myself, and rm /etc/passwd, it asks: rm: remove write-protected file '/etc/passwd'? If I say yes, will it actually delete the passwd file?

View 2 Replies View RelatedI'm guessing this problems came with one of the recent updates but I have no idea what it might be. I can "su" to the root user no problem in bash. However, I can't login to root through gnome on startup, nor can I login when asked to for things like allowing updates through the gui. Basically the root user is unavailable through the gui but is accessible through the command line.
I've had this system for over year and it just started doing this. Does anyone have a clue what I could do to fix this? I have already done the obvious of using "passwd" to change the root password to see if that action would correct whatever went awry without success.
The last update I was able to do, which must be close to the last time I was able to log in as root user was on 24 Feb. 2010 and it installed gmime, mozilla-xulrunner190, libgmime-2_0-3, mozilla-xulrunner190-gnomevfs, mozilla-xulrunner190-devel, gmime-sharp.
I'm on Ubuntu 11.04. I have read around about how to use curl to download a list of URLs from a text file, and everyone says to use Code:curl -K URLlist.txt. This is what the curl man page says as well. However, for even a simple file with one URL, this command outputs a bunch of weird symbols for me instead of downloading the file.For example, I have a text file "test.txt" with one line in the following format:
Code:
url = "http://www.example.com/image.jpg"

I wrote a hack script that outputs the following every so often: Code: 01/04/11 10:33:02: 97,1413,1447,2860 I must leave the data format the same --but I want a special number from it. In this case it's 97 and it's always going to be the first in the 4 columns of comma delimited items. I can extract with this:
Code: cat datafile | awk -F" " {'print $3'} | awk -F"," {'print $1'} But that's really sloppy. Can someone point out a better way of doing this (with awk) and tell me why?

I know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:
1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.
What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.
So I just turned my computer on and it was beeping rapidly, and it would stop if I hit "Enter". Also this came on my screen: Cannot set Fray", something like that. It boots fine..just what is that?

I've been installing/tweaking F12, and I've found something that I can't say I've ever seen or expected to find before: the contents of my ~/Documents folder has lost its permissions and ownership info. I restored it from a backup last night/this morning, and I've rebooted a few times since then. Other folders from the backup are OK, just Documents.I don't know what my options are. I could try to blow it away and restore it, but that doesn't answer what caused it. If there's a "relabel" or something, that might help... though I've never had to do it before. Could it be that after these two-and-some-change years, my hard drive is giving out? Good thing I have a recent backup... but it'd be a shame to lose all my work getting F12 to work again.

They finally stop and this could mean only two things my security measures are working "NOT" or they actually got in. In any case browsing around my system for suspicious changes I found a file"agent.4015" on my tmp folder. This file denies read privileges to root and I?m afraid to chmod until I know for sure what it is.

I have got certain files which somehow contain abnormal character "Del" "0x7f" or 177 which represents Del. And this is causing SVN to reject these files and abruptly end the process.

and further want to replace "Max" by line number so that i can plot the resulting file. i searched in forum, but couldn't do what i wanted to do. e.g. i used
1)grep command
grep -v "Max" inputfile >outputfile
deletes whole line,and hence whole text.
2) sed command
cat inputfile |sed 's/ .{1,12} //g' >outputfile
gives output

When i want to remove particular lines containing a specific word in from entire document at a time,i am using the following command.
awk '$columnno !~/specificword/' inputfile > outputfile
But here, coulmn no is my problem, because iam having this in different columns. So i need a solution for it.
How to write such removal command without mentioning column no. , ie irrespective of column no, it has to remove all lines having that specific word.
