Techniques for Working with Jekyll

Techniques for working with Jekyll

These are notes to help me track how I am using Jekyll.

I’ve created a series of scripts that begin with the word SearchChaio that do useful tasks. I’ve also created a script called create-post.sh that will create a new post.

find . -iname “202?-??-??-*”

sort -n -t _

Learning to search

The following is a direct quote from a conversation with Bing on 9/12/2023.

To extract the last word of a string in bash, you can use the following command:

echo "Some variable has value abc.123" | awk '{print $NF}'

This command uses awk to break the input string into different fields using whitespace as the separator by default. $NF is a built-in awk variable that gives the total number of fields in the current record. Combining $ with NF outputs the last field in the string, no matter how many fields your string contains ¹.

If you want to extract the last word after a specific string, you can use awk with substr and index functions as follows:

echo "Some variable has value abc.123" | awk '{print substr($0, index($0, "value") + length("value") + 1)}'

This command first finds the index of the word “value” in the input string using index function. It then adds the length of “value” and 1 to get the starting position of the last word. Finally, it uses substr function to extract the last word from that position till the end of the string .

To sort and remove duplicate rows from the extracted words, you can use sort and uniq commands as follows:

echo "Some variable has value abc.123" | awk '{print substr($0, index($0, "value") + length("value") + 1)}' | sort | uniq

This command sorts all words extracted from your input string in ascending order and removes any duplicate rows.

I hope this helps!
