UTF-8 Character map file - utf-8

I have a new installation of Arch -- within the past month -- and somehow recently my $LANG variable has gotten messed up. After some searching, trying to run locale-gen it appears somehow the UTF-8 file has disappeared.
[ryan#ARCHER /]$ locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory

en_US.utf8
[ryan#ARCHER /]$ ls usr/share/i18n/charmaps/
[ryan#ARCHER /]$ uname -a
Linux ARCHER 4.1.6-1-ARCH #1 SMP PREEMPT Mon Aug 17 08:52:28 CEST 2015 x86_64 GNU/Linux
I want to simply find somewhere to download or otherwise regenerate the UTF-8 encoding file.

You have to open the file /etc/locale.gen and uncomment the line with the language and encoding options that you want to generate. In my file I have line 163 uncommented, which holds "en_US.UTF-8 UTF-8".
After this you should be able to run locale-gen
This is as decribed on:
https://wiki.archlinux.org/index.php/Locale
I apologize if I misunderstood the question and this is what you have already tried.

How could GMT commandline not be working from one directory (but working from all others fine)?

I have been using a script launching GMT (General Mapping Tool) commandlines from a directory for a while. But now, the GMT commandline is not working in this directory anymore. It just enters and does not output anything, even informations on the version of the commandline.
/media/data/user/weird_directory/child_directory
This weird behavior is only located in the script directory though (weird_directory), and the commandline is working in the child (child_directory) and parent directories (user). I can thus launch my script only from those parent and child directories.
Do you have any idea what I did? What can I do to undo it?
The commandline which gives me problem is:
gmt --version
My path is:
/usr/local/src/SW/BIN/bin:/usr/lib64/qt-3.3/bin:/usr/local/src/SW/QT5/5.1.1/5.1.1/gcc_64/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/media/data/STUD/aargentin/bin
My .bashrc only has inside:
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
Here is my directory content when I use ls -a:

How can I get the builder name of the linux kernel

When the linux kernel booting up,it will print the kernel version and builder, and toolchain infomation. Just like below:
Booting Linux on physical CPU 0
Linux version 3.4.24 (whobuilderthis#cl-builder23)
So how to get the builder whobuilderthis string (using shell)? Where does it store?
Thanks in advance.
You could query /proc/version which should contain the builder string.
shell#android:/ $ cat /proc/version
Linux version 3.0.31-g9f818de (android-build#vpbs1.mtv.corp.google.com) (gcc version 4.6.x-google 20120106 (prerelease) (GCC) ) #1 SMP PREEMPT Wed Nov 28 11:20:29 PST 2012
dmesg gives the kernel log, so you should be able to grep/sed it from there:
dmesg | grep 'Linux version ' | sed 's/[^(]*(\([^)]*\)).*/\1/'
(There are smarter ways of doing this.)
According to Documentation/kbuild/kbuild.rst:
KBUILD_BUILD_USER, KBUILD_BUILD_HOST
These two variables allow to override the user#host string displayed during
boot and in /proc/version. The default value is the output of the commands
whoami and host, respectively.
So "/proc/version" will output the result of current running kernel.
If you want to change the content, you need override the above 2 vars on your kernel build machine.

system(): why do I not have the same permissions when using R in EMACS as I do in the bash terminal?

update: the error only occurs when logged into R from within emacs
what works:
When I ssh into a remote server and run
$ ./foo.rb
from the bash shell, it works. Furthermore, if I launch R and execute
$ R
system('./foo.rb')
I am in a group with permission to read/write/execute the file. File permissions are -rwxrwx---
what doesn't work:
Launch emacs and start an R session:
M-x R
ssh-myserver:.
system('./foo.rb')
I get the following error:
ruby: Permission denied -- foo.rb (LoadError)
why is this? Is there a way to work around this?
I can not find any information from ?system or ?system2

Assuming you started up R as the same user, you do. You error is not coming from a permissions problem for foo.rb, however, or else your shell would be giving the error. (i.e. sh: ./test.rb: Permission denied; see example below). Here, ruby itself is giving the error. Without knowing exactly what is in your foo.rb, I would suggest digging in there to see what it is trying to load/source, and checking the permissions on those.
#!/usr/bin/env ruby
puts 'Hello world'
Now in R....
> system('ls -l test.rb')
-rw-r--r-- 1 jcolby staff 40 Oct 21 08:23 test.rb
> system('./test.rb')
sh: ./test.rb: Permission denied
> system('chmod a+x test.rb')
> system('./test.rb')
Hello world
I presume the M ODULEPATH in the Emacs-derived output is simply a copy and paste typo.
The differences between the two env outputs is much greater than I expected; I've selected the ones that look slightly suspicious to me:
$ diff -u works fails

In the emacs-derived session, your LD_LIBRARY_PATH environment variable may be changing specifics of which dynamically linked libraries are being used when executing ruby. If you ssh in to your server and execute your foo.rb with the changed LD_LIBRARY_PATH, does it work or fail?
LD_LIBRARY_PATH=/usr/lib64/R/lib:/usr/local/lib64:/usr/lib/jvm/jre/lib/amd64/server:/usr/lib/jvm/jre/lib/amd64:/usr/lib/jvm/java/lib/amd64:/usr/java/packages/lib/amd64:/lib:/usr/lib ./foo.rb
The PATH environment variable between the two sessions is different; perhaps you have permission to execute /usr/local/bin/ruby (or the libraries in /usr/local/lib/ruby/) but not /usr/bin/ruby (or the libraries in /usr/lib/ruby/). Does your script use #!env ruby or does it use #!/usr/bin/ruby (or some other fixed path)?
Your pwd in one instance is /home/dleb, the other /home/a-m/dleb/pecan -- but HOME is set to /home/a-m/dleb on both systems. Is /home/dleb a symbolic link or does it actually exist separate from /home/a-m/dleb? (This really is grasping at straws -- I don't think this is it, but this problem is baffling.)
One last thing to consider: is your server confined with a tool such as AppArmor, SELinux, TOMOYO, or SMACK? Any of these mandatory access control tools can prevent an application from writing in specific locations, perhaps they aren't yet configured for your site. Check dmesg(1) output to see if there are any rejection messages, most or all these tools log to dmesg(1) if auditd(8) isn't running.

Getting U-boot's Version from Userspace

Does anyone know of a way to get U-boot version installed from userspace? There is the fw_printenv command that provides access to U-boot's environment variables, but not the version.
If U-boot is located in mtd0, you can get version info as follows:
root#SUPERWIFI:/proc# strings /dev/mtd0 | grep U-Boot
U-Boot 1.1.4-g1c8343c8-dirty (Feb 28 2014 - 13:56:54)
U-Boot
Now running in RAM - U-Boot at: %08lx
Just an update for this.
In our version of U-Boot we changed the code for main_loop() in main.c to this:
#ifdef CONFIG_VERSION_VARIABLE
char *oldver=getenv("ver");
if(oldver==0 ||strcmp(oldver,version_string))
{
setenv("ver", version_string); /* set version variable */
saveenv();
}
#endif /* CONFIG_VERSION_VARIABLE */
So setenv/saveenv is only called, if needed by an update.
In our firmware we added
/sbin/fw_printenv -n ver > /var/config/u-boot.ver
to make the u-boot version public available.
There's no defined way to do this. Once Linux boots, u-boot is no longer running and it's RAM is reclaimed for Linux's use. Linux doesn't even know about u-boot. Nor does it have to have been booted by u-boot.
If you really want to do this, the only way to do it is to add the u-boot version to the kernel's command line, write code to scan the u-boot image in flash for it's version, or something even nastier.
An alternative solution is to read the version directly from the u-boot binary file (can be even embedded in an image file containing other binaries as well like e.g. the first stage bootloader) with e.g. mmcblk0boot0 as partition (of device mmcblk0) the bootloader resides in:
sudo grep -a --null-data U-Boot /dev/mmcblk0boot0
Site note: Does work not only for Arch Linux but e.g. Ubuntu as well.
In my devices UBoot automatically creates a "ver" environment variable containing its version:
U-Boot > printenv
baudrate=115200
ethact=FEC ETHERNET
ethaddr=24-db-ad-00-00-08
bootdelay=3
bootcmd=bootm fc080000 - fc060000
bootargs=console=ttyCPM0,115200n8 rdinit=/sbin/init
stdin=serial
stdout=serial
stderr=serial
ver=U-Boot 2009.03-svn9684 (Mar 08 2010 - 17:08:32)
Environment size: 253/131068 bytes
U-Boot >
I don't use fw_printenv, but I would imagine that this variable gets passed along as well. Maybe you already have something similar in your system?
UPDATE (5/23/2012):
I added fw_printenv to my linux image and can confirm that I do see the "ver" variable:
[root#ST600 /]# fw_printenv
baudrate=115200
ethact=FEC ETHERNET
ethaddr=24-db-ad-00-00-08
stdin=serial
stdout=serial
stderr=serial
ver=U-Boot 2009.03-svn9684 (Mar 11 2010 - 09:43:08)
bootcmd=bootm fc080000 - fc060000
bootdelay=3
bootargs=console=ttyCPM0,115200n8 rdinit=/sbin/init panic=10 mem=32m
[root#ST600 /]#
Try to read uboot version this way:
Find uboot partition, eg. for MTD device:
cat /proc/mtd
For /dev/mtd5:
cat /dev/mtd5 | hexdump -C -n 64
You can't rely on fw_printenv if you want to know u-boot version.
fw_printenv just looks for the printenv partition and dumps its data. So it's OK for normal variables, but it's not OK for the "ver" variable, which is dynamic, and whose value is initialized by u-boot when it boots. The value of this variable doesn't remain after u-boot exit, except if you manually save it to environment.
For example, on my board, if I print the "ver" variable from u-boot prompt:
U-Boot > printenv ver
ver=U-Boot 2009.11-00393-g5ca9497-dirty (Nov 26 2012 - 11:08:44)
This is the real version of u-boot, coming from u-boot itself.
Now, if I boot my board and use fw_printenv:
el#board # fw_printenv | grep ver=
ver=U-Boot 2009.11-00323-gbcc6e0e (Sep 21 2012 - 11:07:19)
As you can see, it's different. Because it happens that I have a "ver" variable defined in my environment. And it doesn't match the real u-boot version.
Of course, I could go back to u-boot, use "saveenv" to update the "ver" value in the environment. Then the two values would match. But then, I should always update the environment after changing u-boot.
So, my conclusion is that using fw_printenv to get u-boot version is definitely not a good idea.
If u-boot is residing in an MTD partition then this will work:
U_BOOT_VER=$(for part in `grep u-boot-[01] /proc/mtd | cut -f 1 -d ':'`; do strings /dev/${part} | grep "^U-Boot.*("; break; done)

Problem with Ant's AnsiColorLogger in Snow Leopard

I have Ant configured to use the AnsiColorLogger. In Mac OS 10.5, everything was fine. Since upgrading to Snow Leopard, the AnsiColorLoggger no longer works. I see the Ant output (uncolorized) for a second then it just disappears. Has anyone else gotten this working in Snow Leopard? Other ANSI colors are working fine in Terminal.app (colored ls output, colors in my prompt).
Also, would this be a better question on SuperUser?
UPDATE: I have sorted out the issue. It has to do with ANT giving escape sequences that while appropriate for a linux xterm, are NOT correctly interpreted by Mac OS X. It is possible to filter the ANT output to convert these sequences and restore colorized output.
The moral of the story is that this wrapper script will achieve colorized output:
# cat /workspace/SDK/bin/ant-wrapper.sh
/usr/bin/ant -logger org.apache.tools.ant.listener.AnsiColorLogger "$#" | perl -pe 's/(?&lt=\e\[)2;//g'
# alias ant='/workspace/SDK/bin/ant-wrapper.sh'
# ant publish
(output has lots of pretty colors; well, maybe not so pretty, more like an easter egg)
Original Post (and debugging steps):
I'm having similar issues with regard to AnsiColorLogger not displaying colors at all. I'm not sure what the author means by "[output appears] for a second then it just disappears". That seems like a strange problem to occur on the Terminal.
My Box:
# uname -a

This is the ANT Logger we are using:
http://ant.apache.org/manual/listeners.html#AnsiColorLogger
Here's a related forum post (tried the advice given, to no avail): http://ant.1045680.n5.nabble.com/Macosx-and-AnsiColorLogger-td1355310.html
I did "ant | less", and I DO see escape sequences, but still no colors:
Buildfile: /workspace/Words/words_blackberry/build.xml
ESC[2;32m
publish:ESC[m
Still blocked on this, and would love advice if anyone has gotten it to work on OSX
GOT IT!
So here's the output of colorized ls:
# CLICOLOR_FORCE=exfxcxdxbxegedabagacad ls -lGF | less
total 112

lrwxr-xr-x 1 ddopson admin 36 May 23 21:20 ESC[35mimagesESC[mESC[m# -> ../artwork/output/blackberry/images/
Notice how the escape sequences are subtly different; they don't have the '2;' like ANT did...
So to test this theory:
ant -logger org.apache.tools.ant.listener.AnsiColorLogger publish | sed 's/2;//g'
... and the output is COLORIZED! Victory!
I've take ddopson's knowledge and crammed it into a single line:
ant () { command ant -logger org.apache.tools.ant.listener.AnsiColorLogger "$#" | sed 's/2;//g' ; }
This works by using a Bash Function. Place this in your ~/.profile file and it will do the same thing as ddopson's ant-wrapper.sh, but without needing a second file to make it work. Slightly more elegant and less fragile.
