I recently installed Cygwin. Its default home directory is
/cygdrive/c/Users/<username>/AppData/Roaming/SPB_Data
[Editor's note: this also applies when the directory is /cygdrive/c/SPB_Data.]
I have tried changing the db_home setting in /etc/nsswitch.conf according to this post, but that doesn't make any difference.
How do I change the home directory to /cygdrive/c/Cygwin64/home?
With high likelyhood you have installed some software from Allegro (now owned by cadence) after installing cygwin.
Allegro overwrites the windows system variable 'HOME' and sets it to 'C:\SPB_Data'
To fix this delete the enviroment variable, then the home folder can be set according to the linked stackoverflow question.
Alternatively you could set the correct home folder path in the enviroment variable, but this is not reccomnended according to cygwin documentation.

I registered to reply to this old question since it is the top result on google (for me at least) when searching for 'cygwin SPB_data'. And this question sendt me in the right direction, but did not contain the correct answer.
see https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch
and set on /etc/nsswitch.conf
db_home: /home/%U
Don't use notepad as it will set the line end to windows default CRLF
After changing the file, close all cygwin processes, as its value is read at
cygwin start.

I recently installed cygwin, and have been unable to find my passwd/etc file in order set to HOME. Is there any way to force cygwin to generate the file?
The /etc/passwd and group files are no longer generated by default, starting with Cygwin 1.7.34.
You can still generate them. Cygwin will use these files preferentially if present, by default, but only to cater to existing installs and special situations.
When these files are not present, Cygwin now uses the native Windows user management mechanisms: Active Directory where present, or SAM where not.
It is therefore recommended that you use this new mechanism to change your home directory. The easiest way I know of to do this is to add a line like this to your /etc/nsswitch.conf file:
db_home: /%H
That will change your Cygwin home directory to be equal to your Windows user profile directory. There are many other legal % tokens you can use here to achieve different results. See the previous link for details.
In my case, I set db_home: /%H in /etc/nsswitch.conf file, and change permission of my .ssh dirctory to "full control".
I am quite new to Linux so I'm sorry for my newbie question,
but for about and hour now I'm trying to add Node.js to $PATH with no luck :(
I've used the following line to add Node
PATH=$PATH:node-v0.10.24-linux-arm-armv6j-vfp-hard/bin
it worked, but when I logged off the terminal and logged in again, the path disappeared.
Later I tried adding the same line to .profile , .logins.defs and .bashrc.
All didn't work so I removed the line.
Please help me with this!
P.S , when I added the line to .profile I was able to call Node, but when I changed my directory in order to navigate to a Node project directory, I received the following error:
-bash: node-v0.10.24-linux-arm-armv6j-vfp-hard/bin/node: No such file or directory
You should add an absolute path, not a relative one. You added this to your path: node-v0.10.24-linux-arm-armv6j-vfp-hard/bin. That's a relative path, not an absolute one (absolute paths start with a /). You can change your line to:
PATH=$PATH:DIR/node-v0.10.24-linux-arm-armv6j-vfp-hard/bin
where DIR is the full path of the directory containing node-v0.10.24-linux-arm-armv6j-vfp-hard.
It's probably a good idea for you to read a bit on how this all works - it's not that complicated once you see it explained. See https://superuser.com/questions/238987/how-does-unix-search-for-executable-files for an example.
You have $HOME already set to your home directory.
So you can use this in your .profile:
PATH="$PATH:$HOME:$HOME/bin:$HOME/node-v0.10.24-linux-arm-armv6j-vfp-hard/bin"
If you set it as an absolute path you will not be able to copy that .profile to another user who is set up similarly.
I see there is another question that deals with installing node.js on Debian - and must admit I am surprised it is installed per-user. So if you do the install for another login you might want to copy your .profile to the new login to solve this same issue. There would be no per-user editing required if you use the $HOME variable like this. Just a simple copy or cut and paste.
For reference, here is that other question/answer: install node.js on debian
The current directory on cygwin is home/myuser. I navigated to cygwin and found it has a directory called home/myuser and could not figure out how I would navigate to the desktop. I did not want to add a desktop directory there and I could not navigate above the root folder (cygwin). Any idea on how I could do this?
This is essentially covered in the Cygwin FAQ under "How can I access other drives?". No, you're not trying to access another drive, but you are trying to access a folder outside of the Cygwin tree. As the FAQ item says, Cygwin maps your Windows drives as /cygdrive/<drive-letter>, so your desktop is likely something like /cygdrive/c/Users/<username>/Desktop. Note that the path has changed over the years with various versions of Windows and you didn't specify what version you're running, so it may not be exactly that.
Anyway, what I would do, would be to create a symbolic link to that from my Cygwin home folder. Something like this:
ln -s "/cygdrive/c/Users/<username>/Desktop" Desktop
I put the quotes in because depending on what version of windows you have, this path may include spaces.
You'll probably notice from the FAQ that the Cygwin version of bash accepts DOS-style pathnames, so you can actually do the following:
cd "C:/Users/<username>/Desktop"
But I recommend avoiding such syntax. Not all Cygwin apps understand DOS-style paths, and you'll only end up confusing yourself if you have to try to figure out whether what you're doing will work with a DOS-style path or not. It's best to just use the Unix-style paths for everything when in the Cygwin environment, unless you have a very good reason not to.
Add
cd "/cygdrive/c/Users/<username>/Desktop"
to .bashrc file located in <cygwin install directory>/home/<username>. This will change working directory to desktop every time you open Cygwin terminal.
I have msysgit installed in my PC. I want to change the path of / using environment variables. Currently it is pointing to c:\program files\git. How can I change this?
Note: I am able to change path of ~ directory using HOME environment variable. I am looking for similar solution for this.
The software package that installs git bash is similar to Cygwin (I think it may be based on Cygwin, but I'm not sure of that). It's designed to emulate a UNIX-like environment under Windows.
As far as I know, the location of the / directory (referred to as the root directory) is fixed when you install the software. If you want / to refer to a different location in the Windows filesystem, you'll need to reinstall the software and, if possible, specify a different location. It can't be changed by setting an environment variable.
What exactly are you trying to do? There may be some way to accomplish your goal other than changing the location of /.
I've just been setting up a Ubuntu workstation and wanted to add some settings to eclipse.ini. When I searched for the file I found:
/etc/eclipse.ini
/usr/lib/eclipse.ini
My questions are:
Does Eclipse actually use both files?
If so, in what order does it read them?
How does it merge them?
Both of the files I found are system wide, is there a location in my home directory I could put one that would effect only my instances?
Here's how to determine which eclipse.ini file you should use (joomla.org):
If you downloaded Eclipse IDE manually from internet the "eclipse.ini" file is just inside the unpacked folder
If you installed Eclipse via terminal or software center the location of the file is "/etc/eclipse.ini"
In some Linux versions the file can be found at "/usr/share/eclipse/eclipse.ini". Do not use this file if you found a config file at "/etc/eclipse.ini".
To be sure where your Eclipse folder is, check $ECLIPSE_HOME, and if not specified (these directions at least work for Juno):
Open Eclipse as you normally do.
Click Help -> About Eclipse SDK
Click Installation Details
Go to the Configuration tab
Find "eclipse.home.location=file:PATH". PATH is where eclipse is installed.
sources:
http://docs.joomla.org/Configuring_Eclipse_IDE_for_PHP_development/Linux:
There is only one file.
lrwxrwxrwx 1 root root 16 Aug 8 2012 /usr/lib/eclipse/eclipse.ini -> /etc/eclipse.ini
You probably have already found this out, chances are when you installed Eclipse the installation created (or you did manually) a file /usr/bin/eclipse which if you check it probably looks like the following:
#!/bin/sh
export ECLIPSE_HOME="/opt/eclipse"
$ECLIPSE_HOME/eclipse $*
especially if you followed instructions similar to the ones like these on If-not-true-then-false
On the other hand if you have installed from a package, I suspect you will find that eclipse ends up in /usr/bin, most likely a symbolic link to /usr/lib/eclipse/eclipse (or at least I found it on my Fedora system after using yum to install eclipse).
I have Ubuntu 18 and eclipse installation is squashed in a file
/var/lib/snapd/snaps/eclipse_40.snap
which is mount on /snap/eclipse/40 as read only. Just run
mount | grep eclipse*.snap
This eclipse.ini file is really read only, that means, you cannot modify it, even with sudo. However, I also have a eclipse.ini.ignored file in HOME/.eclipse/some number/configuration. This is being by default ignored, but you can change the "launcher.ini" in the eclipse launcher command.
According to https://wiki.eclipse.org/Eclipse.ini
Eclipse startup is controlled by the options in
$ECLIPSE_HOME/eclipse.ini. If $ECLIPSE_HOME is not defined, the
default eclipse.ini in your Eclipse installation directory (or in the
case of Mac, the Eclipse.app/Contents/MacOS directory) is used.
The certain way to make sure is to run strace on eclipse. In the output you'll see where is eclipse actually trying to pull the file from.
