[0x00404800]> $pmore='b 300;px'
[0x00404800]> $
$pmore
[0x00404800]> $pmore=
[0x00404800]> $
A single $ in the above will list all defined aliases. It's also possible check the aliased command of an alias:
[0x00404800]> $pmore?
b 200; px
Can we create an alias contains alias ? The answer is yes:
[0x00404800]> $pStart='s 0x0;$pmore'
[0x00404800]> $pStart

The r2pipe api was initially designed for NodeJS in order to support reusing the web's r2.js API from the commandline. The r2pipe module permits interacting with r2 instances in different methods:
• spawn pipes (r2 -0)
• http queries (cloud friendly)
• tcp socket (r2 -c)
pipe spawn async http tcp rap json

$ pip install r2pipe
import r2pipe
r2 = r2pipe.open("/bin/ls")
r2.cmd('aa')
print(r2.cmd("afl"))
print(r2.cmdj("aflj")) # evaluates JSONs and returns an object
Use this command to install the r2pipe bindings
$ npm install r2pipe
Here's a sample hello world
const r2pipe = require('r2pipe');
r2pipe.open('/bin/ls', (err, res) => {
if (err) {
throw err;
}
r2.cmd ('af @ entry0', function (o) {
r2.cmd ("pdf @ entry0", function (o) {
console.log (o);
r.quit ()
});
});
});
