From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I need to replace one line in a ton of . json files (hexbear.net)

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)

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
