and Frequently used commands I can’t seem to remember the exact syntax of. Nothin’ fancy.

Linux
find . -name \*.* | xargs grep search_string

navigate to folder you would like to search, enter this command with the search string you would like to find and this command lists all files containing that string

ps x -Ho pid,args

lists all of the processes running

find / -name gcc

finds all folders named gcc


sed '/$/,/' /home/Desktop/jessirae > /home/Desktop/jessirae2

places a comma at the end of each line


paste -sd '\0' - /home/Desktop/jessirae2 > /home/Desktop/jessirae3

The NEWLINE character of every line except the last line in each input file will be replaced with a separator

Ruby

"<a href=\"http://www.oldurl.com\">JessiRae.com</a>".

gsub(/(http?:\/{2})\S+\.(\w+)(\S+)/,"http://www.jessirae.com/blog/")

global substitution replaces all instances of some expression in a string with some other string or performs some function on that string


require 'open-uri'
....
open(url) {

      |page| page_content = page.read()

      page_content

    }

returns html from specified webpage
