I need to replace one line in a ton of . json files

I'm updating foundry to a version 11 and it broke an ass ton of my assets cause they're all "verified version 10"

So all I have to do is change that number, they're just maps so no need to update anything else, but I have like 400+ files to convert all in individual folders.

Please tell me there's an easy way to do this. (I'm on Linux obviously)

for file in $(find . -type f -iname '*.json'); do sed -i 's/"verified":"10"/"verified":"11"/' $file; done
- Find can actually do the sed itself if you don't want to use a subshell and a shell loop.
  
  find . -type f -iname '*.json' -exec sed -i 's/"verified":"10"/"verified":"11"/' '{}' ';'
  
  -print0 | xargs -0 sed -i to get a single sed process working across multiple files.
  
  Add a -P 8 to xargs to get 8 parallel processes.
  
  Today I learned that xargs supports parallelization natively! That's gonna make some of my scripts much simpler
  
  Change the ';' to a '+' for even more efficiency (no need to fork+exec a sed process per file, sed can take multiple files)
- +1
  
  And
  
  In the off chance the files are not under git or some other VCS, might be a good idea to add the -b option to backup
