What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Get the total RESIDENT memory used by processes of a specific name.

This means this is the MINIMUM used by a process, but some memory could be paged out to swap.

bitbucket paginates at around 1360 characters, so if you have several pages of repos in git hub you can just add "?page={1..4}" the url used to get all the repos.

you can also use -v for the deletion curl if you want to see the response from the server.

Finds javascript lodash/underscore methods in source code. It's not perfect as can be ascertained from the last entry in the output. Would be interested if somebody improves this.

i'm using -x :

skip directories on different file systems

so mounts points aren't walked trough

"-F" will continue tailing if file is closed and another file opened with same name. This is handy for tailing log files that segment while watching them without having to issue the command again.

I wanted to count and display the top directories containing JavaScript files in some of my project. Here it is. Maybe it can be written to more simply syntax by using find -exec...

cat configmap.json | jq 'with_entries(if .key == "data" then .value=(.value | to_entries | map( { (.key): (.value|@base64) } ) | add ) elif .key == "kind" then .value="Secret" else . end)'

Functions: cat

simple jq one-liner to convert from configmaps to secrets (which require the values to be base64 encoded).

To automatically pull the config map, convert it, and re-upload the corresponding secret:

kubectl get --export -o json cm [configmap name] | jq 'with_entries(if .key == "data" then .value=(.value | to_entries | map( { (.key): (.value|@base64) } ) | add ) elif .key == "kind" then .value="Secret" else . end)' > secret.json; kubectl create -f secret.json
