Shell command line hybrid binary calculator

When you need a simple calculation, you do not want to use the GUI calculator, can be directly calculated under the shell is the best

Checked, there is a thing called BC, the specific use will not repeat, you can run BC, and then go into the calculation, you can echo the past, probably like this

Echo " 1+2 " | BC Echo " ibase=16;1a+1 " | Bc

However, it is not easy to use, the first is to specify the system, so that the entire expression is this type of, for example

Echo " ibase=16;1a*10 " | BC              0x1A0x10

But I think it would be more troublesome to calculate the 0x1a multiplied by 10 in 10.

If you can have a hybrid into the calculator, think of the fact that you can also package a, as long as the expression, and then the non-10 binary numbers are converted to 10, and then pass the processed expression to the BC, it should be OK.

So, wrote a script, put on GitHub, need to visit HTTPS://GITHUB.COM/ZQB-ALL/SMARTBC

After downloading, you need to add executable permissions, and then link to the place where your environment variables are found

Like what

chmod +x smartbcsudoln -S 'pwd'/SMARTBC  /USR/BIN/SMARTBC

or an individual name.

sudo Ln -S 'pwd'/SMARTBC  /USR/BIN/MYBC

And then you can use it, just look at the help.
