I create the container useing golang reexec， golang executable binary can work, but python (pyinstaller -F ) executable binary not work.
python binary can work on host machine(ubuntu).
-[container]- # ls
123-file functionA functionA-mark python-test test test22
-[container]- # ./python-test
[16] INTERNAL ERROR: cannot create temporary directory!
-[container]- # df -h
df: cannot read table of mounted file systems: No such file or directory
I expect the Python binary to run inside the container.
I`m beginner and don't know where to set it in the container.
I sincerely hope to get your help， thanks

I am pretty new to yocto, I am trying to build a partitioned image using wic command for qemuarm ( Not for a real hardware ).
Steps I followed:
Created a core-image-minimal image for machine qemuarm.
bitbake core-image-minimal
Using wic command to generate a partitioned image
wic create mywksImage -e core-image-minimal
I use a custom wks file whose first line is as below
part /boot --source bootimg-partition --ondisk mmcblk1 --fstype=vfat --label boot --active --align 4 --size 64
Query:
When I run the wic create command above, i get below error
"ERROR: No boot files defined, IMAGE_BOOT_FILES unset for entry #1"
What files should be set for IMAGE_BOOT_FILES when the machine is qemuarm?
Please help.
Had the same problem and found the solution here: https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#conditional-metadata
With the newest Yocto version you need to use : instead of _.
As qemu doesn't seem to use these files you can use any file name existing in DEPLOY_DIR_IMAGE which is build/tmp/deploy/images/qemuarm. In your case your have to add this to the local.conf.
IMAGE_BOOT_FILES:qemuarm = "bzImage"
Running the final image should work with (https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#qemu-dev-command-line-syntax):
runqemu wic

I have a cypher script file and I would like to run it directly.
All answers I could find on SO to the best of my knowledge use the command neo4j-shell which in my version (Neo4j server 3.5.5) seems to be deprecated and substituted with the command cyphershell.
Using the command sudo ./neo4j-community-3.5.5/bin/cypher-shell --help I got the following instructions.
usage: cypher-shell [-h] [-a ADDRESS] [-u USERNAME] [-p PASSWORD]
[--encryption {true,false}]
[--format {auto,verbose,plain}] [--debug] [--non-interactive] [--sample-rows SAMPLE-ROWS]
[--wrap {true,false}] [-v] [--driver-version] [--fail-fast | --fail-at-end] [cypher]
A command line shell where you can execute Cypher against an
instance of Neo4j. By default the shell is interactive but you can
use it for scripting by passing cypher directly on the command
line or by piping a file with cypher statements (requires Powershell
on Windows).
My file is the following which tries to create a graph from csv files and it comes from the book "Graph Algorithms".
WITH "https://github.com/neo4j-graph-analytics/book/raw/master/data" AS base
WITH base + "transport-nodes.csv" AS uri
LOAD CSV WITH HEADERS FROM uri AS row
MERGE (place:Place {id:row.id})
SET place.latitude = toFloat(row.latitude),
place.longitude = toFloat(row.latitude),
place.population = toInteger(row.population)
WITH "https://github.com/neo4j-graph-analytics/book/raw/master/data/" AS base
WITH base + "transport-relationships.csv" AS uri
LOAD CSV WITH HEADERS FROM uri AS row
MATCH (origin:Place {id: row.src})
MATCH (destination:Place {id: row.dst})
MERGE (origin)-[:EROAD {distance: toInteger(row.cost)}]->(destination)
When I try to pass the file directly with the command:
sudo ./neo4j-community-3.5.5/bin/cypher-shell neo_4.cypher
first it asks for username and password but after typing the correct password (the wrong password results in the error The client is unauthorized due to authentication failure.) I get the error:
Invalid input 'n': expected <init> (line 1, column 1 (offset: 0))
"neo_4.cypher"
^
When I try piping with the command:
sudo cat neo_4.cypher| sudo ./neo4j-community-3.5.5/bin/cypher-shell -u usr -p 'pwd'
no output is generated and no graph either.
How to run a cypher script file with the neo4j command cypher-shell?
Use cypher-shell -f yourscriptname. Check with --help for more description.
I think the key is here:
cypher-shell -- help
... Stuff deleted
positional arguments:
cypher an optional string of cypher to execute and then exit
This means that the paremeter is actual cypher code, not a file name. Thus, this works:
GMc#linux-ihon:~> cypher-shell "match(n) return n;"
username: neo4j
password: ****
+-----------------------------+
| n |
+-----------------------------+
| (:Job {jobName: "Job01"}) |
| (:Job {jobName: "Job02"}) |
But this doesn't (because the text "neo_4.cypher" isn't a valid cypher query)
cypher-shell neo_4.cypher
The help also says:
example of piping a file:
cat some-cypher.txt | cypher-shell
So:
cat neo_4.cypher | cypher-shell
should work. Possibly your problem is all of the sudo's. Specifically the cat ... | sudo cypher-shell. It is possible that sudo is protecting cypher-shell from some arbitrary input (although it doesn't seem to do so on my system).
If you really need to use sudo to run cypher, try using the following:
sudo cypher-shell arguments_as_needed < neo_4.cypher
Oh, also, your script doesn't have a return, so it probably won't display any data, but you should still see the summary reports of records loaded.
Perhaps try something simpler first such as a simple match ... return ... query in your script.
Oh, and don't forget to terminate the cypher query with a semi-colon!
The problem is in the cypher file: each line should end with a semicolon: ;. I still need sudo to run the program.
The file taken from the book seems to contain other errors as well actually.
I’m trying to run/load sql file into mysql database using this golang statement but this is not working:
exec.Command("mysql", "-u", "{username}", "-p{db password}", "{db name}", "<", file abs path )
But when i use following command in windows command prompt it’s working perfect.
mysql -u {username} -p{db password} {db name} < {file abs path}
So what is the problem?
As others have answered, you can't use the < redirection operator because exec doesn't use the shell.
But you don't have to redirect input to read an SQL file. You can pass arguments to the MySQL client to use its source command.
exec.Command("mysql", "-u", "{username}", "-p{db password}", "{db name}",
"-e", "source {file abs path}" )
The source command is a builtin of the MySQL client. See https://dev.mysql.com/doc/refman/5.7/en/mysql-commands.html
Go's exec.Command runs the first argument as a program with the rest of the arguments as parameters. The '<' is interpreted as a literal argument.
e.g. exec.Command("cat", "<", "abc") is the following command in bash: cat \< abc.
To do what you want you have got two options.
Run (ba)sh and the command as argument: exec.Command("bash", "-c", "mysql ... < full/path")
Pipe the content of the file in manually. See https://stackoverflow.com/a/36383984/8751302 for details.
The problem with the bash version is that is not portable between different operating systems. It won't work on Windows.
Go's os.exec package does not use the shell and does not support redirection:
Unlike the "system" library call from C and other languages, the os/exec package intentionally does not invoke the system shell and does not expand any glob patterns or handle other expansions, pipelines, or redirections typically done by shells.
You can call the shell explicitly to pass arguments to it:
cmd := exec.Command("/bin/sh", yourBashCommand)
Depending on what you're doing, it may be helpful to write a short bash script and call it from Go.
I am getting this error with GT.M:
%GTM-E-GDINVALID, Unrecognized Global Directory file format: /home/blah/gt.m/example/mumps.gld, expected label: GTCGBDUNX007, found: GTCGBDUNX006
Here is what I did so far:
get the version http://sourceforge.net/projects/fis-gtm/
tar -xzf gtm_V55000_linux_i686_pro.tar.gz
chmod +x semstat2 mupip mumps lke gtmsecshr gtcm_shmclean gtcm_server gtcm_play gtcm_pkdisp gtcm_gnp_server geteuid ftok dse
Now we start like this in Bash:
mkdir example; cd example
...and invoke the mumps from the parent dir:
../mumps -r GDE
The output is this:
%GDE-I-GDUSEDEFS, Using defaults for Global Directory
/home/blah/gt.m/example/mumps.gld
Now we set the working dir to create the gld file.
GDE> change -s DEFAULT -f=/home/blah/gt.m/gt.m/example/
GDE> exit
The output from the command is this :
>%GDE-I-VERIFY, Verification OK
>%GDE-I-GDCREATE, Creating Global Directory file
> /home/blah/gt.m/example/mumps.gld
Now this creates a v6 version of gld, which mupip does not like:
strings mumps.gld | head -1
Which contains this string:
GTCGBDUNX006H
But mupip expects a 7 not a 6!
../mupip create
>%GTM-E-GDINVALID, Unrecognized Global Directory file format: >/home/blah/gt.m/example/mumps.gld, expected label: GTCGBDUNX007, found: GTCGBDUNX006
If I just edit the file and replace the 6 with a 7,
../mupip create.
This works!
Now I have a dat file, and go to gtm to save something :
GTM>s ^foo("blah")=1
%GTM-E-GDINVALID, Unrecognized Global Directory file format: >/home/blah/gt.m/example/mumps.gld, expected label: GTCGBDUNX006, found: GTCGBDUNX007
Oh so that wants a v6, so good thing i backed up the old, one, i replace it .
GTM>s ^foo("blah")=1
that works
GTM>zwr ^foo(*)
>^foo("blah")=1
So the data is stored.
Can anyone please explain this? In detail? Why does mupip operate with a different version number?
Note, I did not run any other commands, I am just learning and don't want to execute any huge install routines a root that I don't understand.
In your steps you don't show whether you installed GT.M or not.
That is only the unziped version, first:
chmod 777 configure
./configure
The installation will produce new files in the gtm_dist directory.
You either have GT.M already installed (and I would guess it is an older version) on your system somewhere else and have some environment variable defined for it in your bash/tcsh/*sh environment, or you didn't provide all the step you did to get to that error.
My guess is that you already have GT.M installed somewhere and your above commands uses part of that installation. You can easily verify this using this command : env | grep gtm.
If I follow your steps mentioned above, I get this result :
laurent#laurent /tmp/test $ tar -zxf ~/Projects/gtm_V55000_linux_i686_pro.tar.gz
laurent#laurent /tmp/test $ chmod +x semstat2 mupip mumps lke gtmsecshr gtcm_shmclean gtcm_server gtcm_play gtcm_pkdisp gtcm_gnp_server geteuid ftok dse
laurent#laurent /tmp/test $ mkdir example; cd example
laurent#laurent /tmp/test/example $ ../mumps -r GDE
%GTM-E-GTMDISTUNDEF, Environment variable $gtm_dist is not defined
So, I as said, you either did something else, or have a different GT.M version already installed and this is why some commands expect different versions of GLD.
As Bhaskar has noted in your cross post on Hardhats. Make sure you follow the installation instructions for GT.M. Instructions can be found in Chapter 2 of the UNIX Administration and Operations Guide
