In Linux, Is there a way to remember/change a path to a USB device? In my case, I need linux to remember that my USB serial adapter will stay on /dev/ttyUSB0, but when I unplug it and plug it back in, it switches to /dev/ttyUSB1. I'm using a debian-based distro(mint)

How shall i go about changing the absolute path to relative path, so that /home/git/mirror/android/adb/ndk.git gets converted to /mirror/android/adb/ndk.git //echo <command> "$prefix$PWD.git" ?? - anything for relative path?
I need to set the default input device to be the microphone on my webcam for when I skype, but it seems to keep resetting itself, so I keep going in and changing it.

I was changing my sudoers file to give permission of using "sudo" command to all root commands, asking for the password. It works, it's fine. The problem I'm having is with the variable PATH to my user, I think.
In terminal:
normal user:
Code:
ataias@ataias-notebook:~/Downloads$ echo $PATH
/usr/local/bin:/bin:/usr/bin
super user:
Code:
root@ataias-notebook:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin
As many commands are in /sbin/, root can use them without writing "/sbin/" but I can't do the same cause it's not in my path.
while root do this:
Code:
shutdown -h now
I should do:
Code:
sudo /sbin/shutdown -h now
and I want to use only
Code:
sudo shutdown -h now
I want to change my user's path variable to make it equal to root's path. how to change it? I don't know many things of shell still.

I want to be able to change the root device, say from sda to sdb, so that I am able to remove sda. I don't believe this is possible with chroot, as I am changing the root folder to a mount point that exists on sda (sdb is not on fstab), so removing it would lock up the system.
Any thoughts how I can do this?
I use this command:
Code:
find ./ -atime +360
to figure out the files that haven't been accessed since 360 days. The command above will return results like this:
Code:
/uploads/2010/02/some-file-name.ext
/uploads/2009/08/another-file-name.ext
... etc
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
Code:
mv /uploads/2010/02/some-file-name.ext /old-files/uploads/2010/02/some-file-name.ext
But I want the executed command to create this path
Code:
/old-files/uploads/2010/02/
If it doesn't exist.
I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?
Experimenting with shell variables, accidentally deleted the path variable how could I return to the original path value. What kinds of problems will I have if I don't have a path variable.

View 1 Replies View RelatedI currently have 3 drives installed to be used as a file server.
1 holds the Ubuntu OS
The other is the file server drive with 1 additional for backup using raid1.
2 Questions:
1) How do I get to the drive or Raid device to put files on the drive using command line (the 2 drives are sda & sdc that are connected to the raid1 device)?
2) How do I set the path in Samba to connect to this RAID drive.
Currently I have 5 HID's I would like to use on the system at any given time. However, I have the problem of them using different device paths depending on what order I plug them in... Which wreaks havoc on qjoypad and also my music software which looks for a specific device number, which may or may not be the same as it was last time.
For example, I have 2 rock band drum controllers which I use to send MIDI signals. I need them always assigned to the same device path, so that I don't have to change the settings in my music software every time I run it, to make sure it's looking at the right controller
Or if I am going to play games with a gamepad, but I also have the drums hooked up, the gamepad may be assigned to /dev/input/js2, so I create my qjoypad profile.... Let's say the next day I reboot with the drums not plugged in, the gamepad is now /dev/input/js0, and the qjoypad profile won't work because it is looking for that gamepad at /dev/input/js2... So I would either have to create a new profile, or hook the drums back up in the same order ... Or something
It's just a mess...
Is there any way to tell Ubuntu to say "/dev/input/js0 is always Playstation gamepad", "/dev/input/js1 is always drum pad 1", etc.?
Or some way to do away with /dev/input scheme altogether and somehow link directly to the name of the device?
I have a dual boot Win 7 and Ubuntu 11.04 I just started setting up - and know almost nothing about Linux - I have all my data on separate drives from my OS drives, and would like to "arrive" at my "My Documents" file when i choose "Documents" in Ubuntu.
The location of "My Documents" is - /media/New Volume/My Documents (which I found by dragging the folder onto the terminal) not quite sure how to put in the right command - something like ln -s /media/New Volume/My Documents ~Documents - (but that isn't right and didn't work).I also want to do the same with Music, Pictures and Videos.

View 2 Replies View RelatedI just set up an internal mail server for my office using Postfix, Dovecot and Squirrelmail. It works great except for one tiny problem. When I send mail, I address it to user@myoffice (no .com, .net, etc) and it works perfectly. However, somewhere in my work, I screwed up and for whatever dumb reason put myoffice.net somewhere in there and now the return-path always shows up as user@myoffice.net instead of just user@myoffice. Does anyone know how to fix the return-path so that when someone clicks reply it goes to user@myoffice?

View 1 Replies View RelatedWe have a custom app that runs on boot on some older hardware running DSL linux, and their startup manager was quite simple. We purchased some newer Asus eeebox's which run xandros and things are quite stable and run nice with 1 exception.The application only runs from the root (/) location. This box auto logs in as 'user' and there is a /home/user/.kde/Autostart folder where you can stick scripts to run at boot. So I have a start.sh script, and with little bash programming tried things such as;
sudo cd /
sudo /startapp.pl
but the errors start spewing with the basic;can't find data/xyz as it's looking in the local.I thought there was a basic cwd (change working directory) but everything I try just forces the run from that location.Any ideas or suggestions are appreciated, but things like can you change the code, etc. can't be done, so it must be a programming thing. The only other thought I had but not sure, can you do a cronjob with @boot or something, that when the box starts, it can run this job as root and fire off?
Can I change the default path for any or all of the different crontab files?
Can they be changed independently? for example can the user mark get one path for cron jobs, Lynn get another, and root get yet a third, or are they always going to be the same?
How do I change them?
Hello fellow Linux users:
I know there are several crontab files on my computer. One each for each user, and it looks like one for root, maybe others?
I think there is only one cron handler that reads all the different crontab files and does what it is told.
If I do from my command line, I get:
Code:
mark@server:~$echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
If I schedule a similar command in my own crontab file by using
Code:
mark@server:~$crontab -e

View 2 Replies View RelatedI'm writing an application with a plugin architecture and would like modify (specifically add to) the dynamic library search path while the main executable is running.
The plugin paths are not known until the application is running so I can't set LD_LIBRARY_PATH ahead of time.
My understanding (although I haven't tested it) is that the executable will only parse the LD_LIBRARY_PATH once, early on, so modifying this environment variable at runtime will have no effect.
(Note - on Windows the solution is to modify the PATH environment variable)
I know it's possible to specify the full path to load a dynamic library, and this would work if the plugin(s) only had a single library to load, but some of them will have a bunch of libraries with their own inter-dependencies, so I'd like the plugin folder(s) to get added to the search path to pick up the dependant libs.
