How2

Allows searching stackoverflow.com from the command line and viewing the code solutions. Based on same idea as https://github.com/santinic/how2 I couldn't get the npm to install so I wrote my own version in java.

It's a single file that I place in and then alias.

Usage

how2 "search query" [numberOfResultToDisplay] [open]

One argument e.g. how2 "java hello world" = Searches google for stackoverflow results. Two arguments e.g. how2 "java hello world" 0 = Show the first result Three arguments e.g. how2 "java hello world" 0 open = Open that page in browser

Install Linux

mkdir -p ~/bin
wget -q -O bin/how2.jar jpad.io/how2.jar 
echo "alias how2='java -jar ~/bin/how2.jar'" >> ~/.bashrc
source ~/.bashrc

Examples

> java -jar how2.jar "bash set environment variable" 0
Setting environment variables in Linux using bash - Stack Overflow
----------------------------------
export VAR=value will set VAR to value. Enclose it in single quotes if you want spaces, like export VAR='my val'. If you want the variable to be interpolated, use double quotes, like export VAR="$MY_OTHER_VAR".
export VAR=value
export VAR='my val'
export VAR="$MY_OTHER_VAR"
