JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

If you’re trying to delete a very large number of files at one time (I deleted a directory with 485,000+ today), you will probably run into this error:

/bin/rm: Argument list too long.

The problem is that when you type something like “rm -rf ”, the “” is replaced with a list of every matching file, like “rm -rf file1 file2 file3 file4” and so on. There is a reletively small buffer of memory allocated to storing this list of arguments and if it is filled up, the shell will not execute the program. To get around this problem, a lot of people will use the find command to find every file and pass them one-by-one to the “rm” command like this:

find . -type f -exec rm -v {} \;

My problem is that I needed to delete 500,000 files and it was taking way too long.

Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!
