My purpose is to have a different history file for each directory. Because, it would be usefull for me to access only to commands executed in each directory. In this context, is there any way to update the HISTFILE variable every time I go in a directory?
View 1 Replies'readonly HISTFILE'
but the user could tamper with the histfile itself. Like:
rm -f $HISTFILE;
rm -f $HISTFILE; mkdir $HISTFILE;
rm -f $HISTFILE; ln -s /dev/null $HISTFILE;
I'm experimenting with PROMPT_COMMAND to execute a command each time the user executes a command and so log it somewhere else.This post was pruned from the 2009 Is there a way to prevent users from changing or unset their HISTFILE variable? thread. Please do not resurrect old threads but instead create your own (and maybe provide a link to the old one).
I use rsyc for synching files that I type with a server and every time I have to enter the server's password. Right now in my .bashrc file there is an alias like this code...
but can't find such a thing in rsync or ssh man pages. Does anybody know what I should do?
Code:
wh1sk3yj4ck@valkyrie:~/.vmware$ ls -l
total 32
drw-rw-rw- 2 wh1sk3yj4ck wh1sk3yj4ck 4096 2010-08-05 08:06 BT4-R1
It would seem as if I own that dir, yea?
Well.
Code:
wh1sk3yj4ck@valkyrie:~/.vmware$ cd BT4-R1/
bash: cd: BT4-R1/: Permission denied
Also, what does the '2' mean after the permissions?
My question might sound pretty nooby - still having my first Ubuntu cup after a Windose life Every time at logon i have to enter my wireless key - is there a way to save it so I dont have to enter it every time?
View 3 Replies View RelatedIt seems that karmic has changed the behavior of Gnome's cpufreqselector, so that it requires root authority to make changes, and those changes don't persist after a reboot.
Is there a way to make changes persistent? Is there a way to let admin users change the setting without having to enter a password every time?
i'm trying to get everything working ok. i have installed ubuntu using wubi and i've found that i can access my files on my windows partition from ubuntu. to do this i have to mount the disk and enter the password each time i boot up, and i would like this to be done automatically. i was wondering if this was possible? i put in a link directly to the music folder on windows into my 'places' but it only appears once i have put the password in. its not a huge thing, but its one of those things which would make starting up my ubuntu a lot more conveniant.

View 14 Replies View RelatedI use ext4 for the lvm2 home partition on Fedora 11. Yesterday, I must shrink my home partition and the operation crashed. Then a new ext4 partition becomes a backup "cp -R /mnt/backup/* /home" + chown + chgrp and boot Fedora again.
The login failed and the message of Fedora is "Cannot enter home directory. Using /."
What is the problem?
I've installed F14 to replace another distribution on my PC. I chose to use KDE. I used to have a separate partition for my user home to be mounted as /home. During the installation I instructed the installer to do so (without formatting of course). At the first boot I created a use with the very same name as I used to have. I got the warning about the home being already there and I said "yes, convert that ownership and selinux stuff so I can use that very directory as my home". At the graphical login I get a dialog saying I cannot enter my home and that it will use / instead. Of course the login process fails. If I switch to the character console (CTRL-ALT-F2) and do a login I actually get the very same error. But, if I hit "cd" (change directory to $HOME), then I get in the proper directory.
Update 1. I guessed it was a SELinux problem. And I manually disabled it into /etc/selinux/config. Now I'd like to fix this issue, because I'd like to have SELinux working.
I get this error when I boot opensuse default and fail safe. It takes me to a console log in, which works. This happened after new kernel install in Linux Mint, which is unbootable atm. I can boot windows, bsd but no Linux.

And I wanna enter that dir from another Linux machine using Terminal or Virtual Console. In Windows it would start (if I'm not wrong) with "\...". Then a machne name and so on. But if I wanna do it in Linux, I personally only can use Gnome DE with its network..

I have a problem from time to time. Now is such a time. Nautilus is not able to read/enter my own home directory. It can enter/read ANY other directory, but my own home directory. Killing the Nautilus process, doesn't help. Logging out doesn't help. I need to reboot to get nautilus to read my home directory. Sometimes, it suddenly appears after a couple of minutes, but not always. What is taking so long time or causing the hanging? What should I do?
View 4 Replies View RelatedI was reading that if I want to do a one time scheduled command, I should use at, which I've never done, as opposed to cron, which i'm kinda familiar with. But what I want to do is reboot my server at 3am tomorrow and force it to check the file systems with a shutdown -rF. For this do I even need to use "at" or could I just say shutdown -rF 3:00.Will that also know that I mean 3am tomorrow and not say in 3 minutes from now or 3pm?

How do you set current directory (full path) in an environment variable?
View 10 Replies View RelatedI was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:
init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?
I modified files in several directories, and need to run a diff on the backup I created before modifying the file.
I'm trying to compose a simple shell script to speed up the task, but getting a syntax error.
Here is what I have:
for i in DIR1 DIR2 DIR3 DIR4 DIR5 do;
diff /maindir/subdir/subdir/$i/filename.txt.old /maindir/subdir/subdir/$i/filename.txt;
done
I know the paths are valid, and if I run just the diff command with the actual DIR1 instead of $i it works.
The declaration for directory record length in ext2 filesystem is as follows:
Code:
#define EXT2_NAME_LEN 255
struct ext2_dir_entry_2 {
__u32 inode; /* Inode number */
__u16 rec_len; /* Directory entry length */
__u8 name_len; /* Name length */
__u8 file_type;
char name[EXT2_NAME_LEN]; /* File name */
};
Some say because the record is not in a fixed length so rec_len is the real record length. Why is the length of the array `name' not fixed? I thought C arrays like this should be fixed length. C99 has variable-length arrays, does this structure count on C99?
I am pasting sudo commands without problems as a user (ales in my case) and then immediately the ask the user password.
The keyboard seems to be dead, no keys work, not allowing me to enter the password.
Succeeded in connecting to internet using my wll phone. I can now connect using 'wvdial' command in root terminal. But I want to connect through terminal. I tried 'sudo wvdial' command. Then I am asked for my password. But I cannot type my password there. When I type, nothing appears on the terminal window. Ofcourse there's no problem with my keyboard.
View 5 Replies View RelatedI'm still pretty new to linux, and burning through a unix/linux course offered at the local JC. I'm working on an assignment for shell scripting and I need to make a script that displays a bunch of junk (pwd, date, yadda yadda) and then prompts the user to enter a directory so they can view the contents. If it's valid, then it displays the contents. If it isn't then it throws an error message and the script stops. This is done using if, then and else. The problem is, my script always shoots straight to the else, even if the subdir entered IS a valid subdirectory.Here's what I have:
Code:

In my script, I need to get execution time of a command (say 'ls') in mili seconds level. For this i tried using "time" command to retrieve the total execution time in milli seconds. But, the problem is that, how to save the output of time command in a variable. The format of the command is like "time ls -R /opt" Going further, the o/p of 'time' command is:
real 0m0.003s
user 0m0.004s
sys 0m0.000s
Here, in my script, I would like to use only middle line "user 0m0.004s" saved to the variable but unable to find out the way.
I've tried Ubuntu, Arch, and most recently Fedora but the SUSE GNOME environment blows everything else away!
The only problem (so far) is that Network Manager requires you to enter your password every time you login to unlock the password keyring. I want to disable this.
I think some distros disable the prompt by using the login password to unlock the keyring, but I use auto-login (if that makes a difference).
when i use ubuntu one ,i want to upload the whole Directory one time,how can i?there are 200 files in the Directory,if i upload one file one time,it waste my time.
