Shell script command to find specific file extenions-CodePudding

I am looking to locate large files within my GH commit history so that I may find these files and remove them to reduce my repo size.

From this stack overflow threadI have found a shell script that successfully lists files within my repo from largest to smallest

git rev-list --objects --all |
  git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' |
  sed -n 's/^blob //p' |
  sort --numeric-sort --key=2 |
  cut -c 1-12,41- |
  $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest

simply pasting this into my command line outputs the follwoing

etc.
etc.

I would like to add the ability for this script to obtain only files with the .json extension so that I may find all commit hashes and purge from the repo

The thread top comment suggests that further filtering is possible (too low rep to post image):

Currently I have tried similar approaches to this find . -type f -name \*.rb but using .json over .rb and find . | grep *.json however when adding both of these to the script it fails to run within the command line

So really I am just looking for a line that will output only files with the .json extension, if at all possible (apoligies for my lack of experince with shell scripts!)

CodePudding user response：

Change the sed line to

sed -n '/\.json$/ s/^blob//p'

Read up on sed and awk, they're fundamental text-processing tools for any task that falls comfortably into metastasized-oneliner range.
