I have just installed clash from my Linux distribution's repository, and both my Linux distribution and clash are outdated (which, I am not sure, is the cause of the following problem): $ clash -v Clash 1.16.0 linux amd64 with go1.20.8 unknown time I got the following config error when running clash $ clash FATA Parse config error: proxy 3: uuid: incorrect UUID length 4 in string "uuid" I have made ~/.config/clash/config.yaml (whose content is copied and pasted at the end of this post) to be the same as the one in https://doreamon-design.github.io/clash/configuration/configuration-reference.html , except the following part for section proxy-providers (see https://doreamon-design.github.io/clash/configuration/outbound.html for detailed information): proxy-providers: provider1: type: http url: "https://node.freev2raynode.com/uploads/2025/08/1-20250807.yaml " interval: 3600 path: ./provider1.yaml health-check: enable: true interval: 600 # lazy: true url: http://www.gstatic.com/generate_204 test: type: file path: /test.yaml health-check: enable: true interval: 36000 url: http://www.gstatic.com/generate_204 Is the uuid error in ~/.config/clash/config.yaml or https://node.freev2raynode.com/uploads/2025/08/1-20250807.yaml ?

I have the following values in a config.yml file: scratch-org-def: config/project-scratch-def.json assign-permset: false permset-name: run-apex-tests: true apex-test-format: tap delete-scratch-org: false show-scratch-org-url: true I need to replace all occurrences of dashes (-) to the left of the colon (:) with underscores (_). I've tried sed '/.*: /s/-/_/g' config.yml but it replaces all dashes (including the config/project-scratch-def.json). I've tried sed '/^[^:]*:/s/-/_/g' config.yml, hoping to stop at the colon, but it does the same.

I'm using bash shell. I have a YAML file from which I want to remove certain blocks of text. /image-content: post: operationId: createEventPublic summary: Process events description: Process events parameters: [] requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/Content' responses: '201': description: Created content: application/json: schema: $ref: '#/components/schemas/Content' /text-content: post: operationId: createStaticText summary: Process text events description: Process text events parameters: [] requestBody: ... I would like to remove (as an example) the block of text where the path contains "image-content". Normally I can use this to remove a single line with that text sed -i '/image-content/d' ./infile but I'm less clear how to replace every line after that up until the next line that begins with two spaces and a "/" (e.g. " /"). In the above, I would want to remove everything up until /text-content: Edit: Although this may not be valid openapi 3 swagger, I believe it is still a valid YAML file openapi: 3.0.0 components: /static/image-content: post: type: hello /api/hello: post: type: hello /static/css-content: post: type: hello Ultimately, I would like to remove the blocks beginning with "/static". So the ending doc would be openapi: 3.0.0 components: /api/hello: post: type: hello

A bash command: $(System.DefaultWorkingDirectory)/yq_linux_amd64 '. *= load("${{ parameters.HELM_CHART_PATH }}/values/DEV/${{ parameters.COMPONENT }}.yaml")' ${{ parameters.HELM_CHART_PATH }}/values/global-values.yaml > $(System.DefaultWorkingDirectory)/deployment-values.yaml Is merging values from 2 YAML files and sending merged output to a single file. I am unable to understand the syntax from the first single quote until the output is redirected. Can anyone help me understand what it means? Why are both operands after the operator, which is *=? . is the current directory, but what does it mean before *=? Also, why only 1st operand is between load () and what is its meaning?

Here is my YAML file:

network:
  ethernets:
    ens160:
      addresses:
      - 10.200.2.148/22
      gateway4: 10.200.0.1
      nameservers:
        addresses:
        - 1.1.1.1
        - 2.2.2.2
        - 3.3.3.3
        - 4.4.4.4
        search:
        - our.domain

I must replace all DNS addresses under ens160 with two specific addresses. I tried using this:

yq write -i /etc/netplan/00-installer-config.yaml  '.network.ethernets.ens160.nameservers.addresses' ['10.10.10.53','10.10.10.54']

... but all that did was shift all the list items in one like this:

network:
  ethernets:
    ens160:
      addresses:
        - 10.200.2.148/22
      gateway4: 10.200.0.1
      nameservers:
        addresses:
          - 1.1.1.1
          - 2.2.2.2
          - 3.3.3.3
          - 4.4.4.4
        search:
          - our.domain

I don't want that. I need the output to look like this:

network:
  ethernets:
    ens160:
      addresses:
      - 10.200.2.148/22
      gateway4: 10.200.0.1
      nameservers:
        addresses:
        - 10.10.10.53
        - 10.10.10.54
        search:
        - our.domain

It's not very clear how I can do this with yq. How can I accomplish this?

Given a YAML file, example.yaml:

services:
  api:
    image: myImage
    ports:
      - 8080:8080
    environment: 
      - "TEST_STRING_WITH_SPACE=?"

I need to replace the TEST_STRING_WITH_SPACE environment variable value with a multiple words string param. Expected is like that:

services:
  api:
    image: myImage
    ports:
      - 8080:8080
    environment: 
      - "TEST_STRING_WITH_SPACE=With Space"

I'm using yq tool, version: yq (https://github.com/mikefarah/yq/) version v4.44.5 When I try to set value with a string without space, it works: yq '.services.api.environment = "TEST_STRING_WITH_SPACE='$(echo "WithoutSpace")'"' example.yaml But, when I try to set value with a string with space, it does't works: yq '.services.api.environment = "TEST_STRING_WITH_SPACE='$(echo "With Space")'"' example.yaml Got the error: > Error: 1:32: invalid input text "\"TEST_STRING_WIT..." How fix it?

I added this step to CI

-yaml
  check_if_there_is_change:
      - run: 
          name: Check that no git-tracked files were modified
          command: |
          FILES_MODIFIED="$(git status --porcelain)"
        if [[ -n "$FILES_MODIFIED" ]]; then
          echo "The following files were modified or added during the build process:"
          echo "$FILES_MODIFIED"
          echo "This will likely prevent successful publishing. Please run the build locally and include these changes in your pull request)"
          exit 1
        fi

But it fails

IntelliJ shows invalid child element in block mapping. How to change this? I want to know if files have been modified.

I want to use sed to search for line breaks that are not preceded by }. The regex for identifying theses cases is: [^}]$ . What I want to say: If the line ended without } then remove the new line. Any line should end with } before the newline. How to put that in sed to remove them? **EDIT:** Example: {'Date': 'Fri, 19 Apr 2019 07:23:14 GMT', 'Server': 'Apache', 'Vary': 'Qualys-Scan', 'Strict-Transport-Security': 'max-age=31536000;includeSubDomains;preload', 'Set-Cookie': 'ASP.NET_SessionId=ivoa5bhet0s2ygkylmimvkie; path=/; secure; HttpOnly;SameSite=strict, SC_ANALYTICS_GLOBAL_COOKIE=12f133ea; expires=Thu, 19-Apr-2029 07:23:14 GMT; path=/; secure; HttpOnly;SameSite=strict, SC_ANALYTICS_SESSION_COOKIE=336B5|1|ivoa5; path=/; secure; HttpOnly;SameSite=strict, incap_ses_885_270026=cDp/VlO1AHgshF9F6SZID==; path=/; Domain=.zurich.co.uk, ___utmvm=dlNaoEsuXSO; path=/; Max-Age=900, ___utmvay=nWJx01KvGT; path=/; Max-Age=900, ___utm=JZy XEtOwalQ: PtR; path=/; Max-Age=900', 'X-Content-Type-Options': 'nosniff', 'X-XSS-Protection': '1; mode=block', 'Cache-Control': 'private', 'Content-Type': 'text/html; charset=utf-8', 'Keep-Alive': 'timeout=5, max=10', 'Connection': 'Keep-Alive', 'X-Iinfo': '8-3925806-3807 NNNN CT(73 151 0) RT(155583 5) q(0 0 3 0) r(6 6) U5', 'X-CDN': 'Incapsula', 'Content-Encoding': 'gzip', 'Transfer-Encoding': 'chunked'} When I applied your script, it combined the lines.

I am using yq version 4.34.1 in powershell. I try to replace the value of .spec.source.targetRevision in target.yaml with the newer value from a variable $newTargetRevision. So, what I am doing now is as follows. $newTargetRevision = "v1.1.1-1" yq -i '.spec.source.targetRevision = "$newTargetRevision"' target.yaml What I have got is as follows. spec: source: targetRevision: &default $newTargetRevision I expect to get:- spec: source: targetRevision: &default v1.1.1-1 I also tried removing double quotes from $newTargetRevision as follows, but the value in the yaml file is not updated at all. yq -i '.spec.source.targetRevision = $newTargetRevision' target.yaml I try many things but without success. Can you please suggest? Thanks

I am trying to replace a value for key ipAddress using sed for the below yaml block:

networkInterfaces:
- network:
    id: network-1111   
    ipAddress: 192.168.0.0

The command I tried: sed -i 's/\(.*ipAddress:.*\)/ipAddress: 192.168.0.1/g' filename.yaml This actually replaced the text, but it didn't nest the key under networkInterfaces; instead, it placed it in the main block. Output after SED

networkInterfaces:
  - network:
      id: network-1834
ipAddress: 192.168.0.1

I tried yq yq -i '.networkInterfaces.ipAddress = "192.168.0.0"' filename.yaml ... that resulted in an error: cannot index array with 'ipAddress' (strconv.ParseInt: parsing "ipAddress": invalid syntax) I'm looking to replace the value for ipAddress.

I have a simple secret.yaml file:

env:
  USERNAME: user
  PASSWORD: pass

i'm trying to use yq / jq to encode the values for creating k8s secret, so my final result should be:

apiVersion: v1
kind: Secret
metadata:
  name: my-service
type: Opaque
data:
   USERNAME: 
   PASSWORD:

i was trying to use:

yq r secret.yaml ".env" -j | jq -r ' to_entries[] | "\(.value)" | @base64'"

which gave me the base64 encoded values, but i'm failing to insert the encoded values to the final output. i'm trying to avoid using loops but if i won't find a clean solution i'll use it. please assist.

Given a YAML file, example.yaml: node: sub_node: get_this: I'd like to get a variable containing get_this using Mike Farah's yq and the string sub_node yaml="$(cat example.yaml)" nodename=sub_node sub_yaml= "$(echo "$yaml" | yq -r '.$nodename' )"; # also tried -> sub_yaml= "$(echo "$yaml" | yq -r '.'"$nodename" )"; Note this is a contrived example, in reality, the sub_node string is not known in advance so I need to substitute the $nodename string. I can't seem to figure out how to escape out of the single quote query string required by yq. How might I do this?

I am very confused. I installed the Debian package yq But if I call it, jq gets executed:

root@rescue ~ # echo '{"key": "value"}' | yq -p=json
jq: Unknown option -p=json
Use jq --help for help with command-line options,
or see the jq manpage, or online docs  at https://stedolan.github.io/jq 

root@rescue ~ # cat /etc/os-release

In my yaml file I have this persons array (it only has one element always)

persons:
  - name:  mario
    version: 1.0.0
    city: Madrid

how can I replace city to any other value using yq ?

I am new to bash, dragged into a problem where I need to update some dynamic parameters in a yaml file Based on query (search4.subsearch1.name), i need to update

-none
name: old_name

into

-none
name: new_name

* Here is the sample file:

-none
    search1:
    	name: name1
    	pass: pass1
    	date: date1
    #these are just commented texts
    
    search2:
      #Adding few more commented lines
    	myname: somename
    	name: name2
    	pass: pass2
    	someotherparam: param1
    
    search3:
    	nameAndSurname: NS
    	namingConv: true
    	varSet: P3
    
    search4:
        #Again adding some special name: strings here
            myname: somename1
            name: new_name
            pass: new_pass
            ptherparam1: T3
    
    	subsearch1:
        	#Again adding some special name strings here
            	myname: somename2
            	name: old_name
            	pass: pass2
            	ptherparam1: param3
    search5:
        #Again adding some special name strings here
            var1: value1
            name: some_name
            pass: some_pass

So based on query (search4.subsearch1.name), I need to update name: old_name into name: new_name * Expeced output:

-none
    search4:
        #Again adding some special name: strings here
            myname: somename1
            name: new_name
            pass: new_pass
            ptherparam1: T3
    
    	subsearch1:
        	#Again adding some special name strings here
            	myname: somename2
            	name: new_name
            	pass: pass2
            	ptherparam1: param3

Tried with awk and sed but that did not work: lineNR=$(awk "/\
