I have installed mongoDB successfully and now I am trying to setup it so that I can use it through hyper.
Using hyper terminal in my home directory I have created a file .bash_profile
And by using vim editor I edited it as,
alias mongod = "/c/Program\ Files/MongoDB/Server/4.4/bin/mongod.exe"
alias mongo = "/c/Program\ Files/MongoDB/Server/4.4/bin/mongo.exe"
and saved it using the cammand :wq! enter.
Now the terminal is showing,
bash: alias: mongod: not found
bash: alias: =: not found
bash: alias: /C/Program\ Files/MongoDB/Server/4.4/bin/mongod.exe: not found
bash: alias: mongo: not found
bash: alias: =: not found
bash: alias: /C/Program\ Files/MongoDB/Server/4.4/bin/mongo.exe: not found
How can I fix it?
Huh! finally got the solution, removing spaces around the equal sign worked for me.
alias mongod="/c/Program\ Files/MongoDB/Server/4.4/bin/mongod.exe"
alias mongo="/c/Program\ Files/MongoDB/Server/4.4/bin/mongo.exe"

I was just wondering what’s the best way to configure codecov for a monorepo setting. For example, let’s say I have packages A and B under my monorepo. The way I’m currently using codecov is by using a github action codecov/codecov-action#v1, by using multiple uses statement in my GitHub workflow YAML file like the following:-
- uses: codecov/codecov-action#v1
with:
files: ./packages/A/coverage/lcov.info
flags: flag_a
name: A
- uses: codecov/codecov-action#v1
with:
files: ./packages/B/coverage/lcov.info
flags: flag_b
name: B
I know it's possible to use a comma-separated value to upload multiple files, but I have to set a separate flag for each package, and doing it that way doesn't seem to work.
Thank you.
If anyone wants to know my solution, heres what I came up with.
I ended up replacing the github action with my own bash script.
final code
#!/usr/bin/env bash
codecov_file="${GITHUB_WORKSPACE}/scripts/codecov.sh"
curl -s https://codecov.io/bash > $codecov_file
chmod +x $codecov_file
cd "${GITHUB_WORKSPACE}/packages";
for dir in */
do
package="${dir/\//}"
if [ -d "$package/coverage" ]
then
file="$PWD/$package/coverage/lcov.info"
flag="${package/-/_}"
$codecov_file -f $file -F $flag -v -t $CODECOV_TOKEN
fi
done
this is what the above bash script does
Downloading the bash uploader script from codecov
Moving to the packages directory where are the packages are located, and going through all the 1st level directories
Change the package name by removing extra slash
If the directory contains coverage directory only then enter into it, since only those packages have been tested.
Create a file and flag variable (removing hypen with underscore as codecov doesn't support hypen in flag name)
Executed the downloaded codecov script by passing the file and flag variable as argument
I am trying to do the following tutorial:
https://itnext.io/docker-mongodb-authentication-kubernetes-node-js-75ff995151b6
However, in there, they use raw values for the mongo init.js file that is placed within docker-entrypoint-initdb.d folder.
I would like to use environment variables that come from my CI/CD system (Gitlab). Does anyone know how to pass environment variables to the init.js file? I have tried several things like for example use init.sh instead for the shell but without any success.
If I run manually the init shell version, I can have it working because I call mongo with --eval and pass the values, however, the docker-entrypoint-blabla is called automatically, so I do not have control of how this is called and I do not know what I could do for achieving what I want.
Thank you in advance and regards.
you can make use of a shell script to retrieve env variables and create the user.
initdb.d/init-mongo.sh
set -e
mongo <<EOF
use $MONGO_INITDB_DATABASE
db.createUser({
user: '$MONGO_INITDB_USER',
pwd: '$MONGO_INITDB_PWD',
roles: [{
role: 'readWrite',
db: '$MONGO_INITDB_DATABASE'
}]
})
EOF
docker-compose.yml
version: "3.7"
services:
mongodb:
container_name: "mongodb"
image: mongo:4.4
hostname: mongodb
restart: always
volumes:
- ./data/mongodb/mongod.conf:/etc/mongod.conf
- ./data/mongodb/initdb.d/:/docker-entrypoint-initdb.d/
- ./data/mongodb/data/db/:/data/db/
environment:
- MONGO_INITDB_ROOT_USERNAME=root
- MONGO_INITDB_ROOT_PASSWORD=root
- MONGO_INITDB_DATABASE=development
- MONGO_INITDB_USER=mongodb
- MONGO_INITDB_PWD=mongodb
ports:
- 27017:27017
command: [ "-f", "/etc/mongod.conf" ]
Now you can connect to development database using mongodb as user and password credentials.
Use shell script (e.g mongo-init.sh) to access variables. Can still run JavaScript code inside as below.
set -e
mongo <<EOF
use admin
db.createUser({
user: '$MONGO_ADMIN_USER',
pwd: '$MONGO_ADMIN_PASSWORD',
roles: [{
role: 'readWrite',
db: 'dummydb'
}]
})
EOF
Shebang line is not necessary at the beginning as this file will be sourced.
Until recently, I simply used a .sh shell script in the docker-entrypoint-initdb.d directory to access ENV variables, much like #Lazaro answer.
It is now possible to access environment variables from javascript files using process.env, provided the file is run with the newer mongosh instead of mongo, which is now deprecated.
However, according to the Docs (see 'Initializing a fresh instance'), mongosh is only used for .js files in docker-entrypoint-initdb.d if using version 6 or greater. I can confirm this is working using the mongo:6 image tag.
You can use envsubs.
If command not found : here. Install it on your runners host if you use shell runners, else, within the docker image used by the runner, or directly in your script.
(NB: Your link isn't free, so I can't adapt to your situation :p )
Example:
init.js.template:
console.log('$GREET $PEOPLE $PUNCTUATION')
console.log('Pipeline from $CI_COMMIT_BRANCH')
gitlab_ci.yml:
variables:
GREET: "hello"
PEOPLE: "world"
PUNCTUATION: "!"
# ...
script:
- (envsubst < path/to/init.js.template) > path/to/init.js
- cat path/to/init.js
Output:
$ (envsubst < init.js.template) > init.js
$ cat init.js
console.log('hello world !')
console.log('Pipeline from master')
At the end the answer is that you can use a .sh file instead of a .js file within the docker-entrypoint-initdb.d folder. Within the sh script, you can use directly environment variables. However, I could not do that at the beginning because I had a typo and environment variables were not created properly.
I prefer this method because it allows you to keep a normal .js file which you lint instead of embedding the .js file into a string.
Create a dockerfile like so:
FROM mongo:5.0.9
USER mongodb
WORKDIR /docker-entrypoint-initdb.d
COPY env_init_mongo.sh env_init_mongo.sh
WORKDIR /writing
COPY mongo_init.js mongo_init.js
WORKDIR /db/data
At the top of your mongo_init.js file, you can just define variables you need
db_name = DB_NAME
schema_version = SCHEMA_VERSION
and then in your env_init_mongo.sh file, you can just replace the strings you need with environment variables or add lines to the top of the file:
mongo_init="/writing/mongo_init.js"
sed "s/SCHEMA_VERSION/$SCHEMA_VERSION/g" -i $mongo_init
sed "s/DB_NAME/${MONGO_INITDB_DATABASE}/g" -i $mongo_init
sed "1s/^/use ${MONGO_INITDB_DATABASE}\n/" -i $mongo_init # add to top of file
mongo < $mongo_init
I am trying to create a directory structure in Unix. I made the directory using mkdir command with -p option but when i use "touch" to create files i get hit with the "No such file or directory error"
The code i tried .
mkdir -p livingthings{birds/{flyingbirds,nonflyingbirds},plants,animals/{mammals,reptiles}}
touch livingthings/{birds/{flyingbirds/{stork,eagle,eider},nonflyingbirds/{kiwi,ostrich,penguin}},plants/{carrot,cabbage,daisy},animals/{mammals/{jaguar,dog,tiger},reptiles/{alligator,skink,turtle}}}
This is the error which pops out
Help much appreciated.
UPDATE :
After adding the "/" i get one error now that is telling
touch: cannot touch 'livingthings/animals/reptiles/turtle': No such file or directory .:
The issue is you missed the slash after livingthings in mkdir -p livingthings/{birds..... not mkdir -p livingthings{birds.... Because of this it creates a directory named livingthingsbirds instead of livingthings/birds. But then in your touch command u r using livingthings/ so thats why it cant find that directory.
I have written the following code:
#!/bin/bash
#Simple array
array=(1 2 3 4 5)
echo ${array[*]}
And I am getting error:
array.sh: 3: array.sh: Syntax error: "(" unexpected
From what I came to know from Google, that this might be due to the fact that Ubuntu is now not taking "#!/bin/bash" by default... but then again I added the line but the error is still coming.
Also I have tried by executing bash array.sh but no luck! It prints blank.
My Ubuntu version is: Ubuntu 14.04
Given that script:
#!/bin/bash
#Simple array
array=(1 2 3 4 5)
echo ${array[*]}
and assuming:
It's in a file in your current directory named array.sh;
You've done chmod +x array.sh;
You have a sufficiently new version of bash installed in /bin/bash (you report that you have 4.3.8, which is certainly new enough); and
You execute it correctly
then that should work without any problem.
If you execute the script by typing
./array.sh
the system will pay attention to the #!/bin/bash line and execute the script using /bin/bash.
If you execute it by typing something like:
sh ./array.sh
then it will execute it using /bin/sh. On Ubuntu, /bin/sh is typically a symbolic link to /bin/dash, a Bourne-like shell that doesn't support arrays. That will give you exactly the error message that you report.
The shell used to execute a script is not affected by which shell you're currently using or by which shell is configured as your login shell in /etc/passwd or equivalent (unless you use the source or . command).
In your own answer, you say you fixed the problem by using chsh to change your default login shell to /bin/bash. That by itself should not have any effect. (And /bin/bash is the default login shell on Ubuntu anyway; had you changed it to something else previously?)
What must have happened is that you changed the command you use from sh ./array.sh to ./array.sh without realizing it.
Try running sh ./array.sh and see if you get the same error.
Instead of using sh to run the script,
try the following command:
bash ./array.sh
I solved the problem miraculously. In order to solve the issue, I found a link where it was described to be gone by using the following code. After executing them, the issue got resolved.
chsh -s /bin/bash adhikarisubir
grep ^adhikarisubir /etc/passwd
FYI, "adhikarisubir" is my username.
After executing these commands, bash array.sh produced the desired result.
im trying to set the environment path to run pintos command like this in my home floder under ubuntu
set path = ($path /home/pintos/src/utils)
and I type terminal command try to compile this
:~$ source .tcshrc
but it seems get error like this
bash: .tcshrc: line 1: syntax error near unexpected token `('
bash: .tcshrc: line 1: `set path = ($path /home/pintos/src/utils)'
I dont know where is the syntax error is ...
You source your script, which is perfectly valid for [t]csh, into your running shell, which happens to be bash (and not tcsh).
If you're going to use tcsh, just run it (by typing tcsh) and ensure that your ~/.tcshrc has the desired effect. (Then, maybe, use chsh to change your login shell).
If you're going to use bash, set path using PATH=$PATH:/home/pintos/src/utils, in ~/.bashrc and/or in ~/.bash_profile.
