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)

Kickstart driven CentOS 7 install from USB

None of what is written below is particularly original, however, I was unable to find a method documented on the internet at the time of writing that successfully created a kickstart driven CentOS 7 USB installer.

My interest was in doing this manually as I require this USB (image) to be created from a script. Therefore, I did not look into using ISO to USB applications - in addition, these typically do not allow custom kickstart files to be used.

References

Much of the process described below was found on the CentOS Wiki page on Installing from USB key, and from the Softpanorama page on the same subject. I thoroughly recommend reading all of the latter as it highlights the shortcomings/dangers associated with the steps below.

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

1. Generate and add your key to GitHub
2. $ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
3. $ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
4. $ git config --global alias.logs "log --show-signature" (now available as $ git logs)
5. $ git config --global alias.cis "commit -S" (optional if global signing is false)
6. $ echo "Some content" >> example.txt
7. $ git add example.txt
8. $ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)
