Passing input arguments to to a bash alias/function

Question

In bash shell, what is the command to go to a special directory based on two input arguments?

The command I want to get executed is this:

cd /home/btfoouser/mia_YOCTO/build_4/build/tmp-eglibc/deploy/images/p99/

I want to pass build4 and p99 as my input arguments to the cd command from the command line.

For example, the command will be my_cd build_4 p99, which should get translated to

cd /home/btfoouser/mia_YOCTO/build_4/build/tmp-eglibc/deploy/images/p99/

I tried:

alias my_cd ='cd /home/btfoouser/mia_YOCTO/$1/build/tmp-eglibc/deploy/images/$2'

Aliases don't parse arguments. Use a function:

my_cd() { cd "/home/btfoouser/mia_YOCTO/$1/build/tmp-eglibc/deploy/images/$2"; }

To make the function permanent, put it in your ~/.bashrc file.

There is a dirty hack for making aliases take arguments : `alias my_cd='{ read x y; cd "/home/btfoouser/mia_YOCTO/$x/build/tmp-eglibc/deploy/images/$y"; } << – anishsane Jun 17 '16 at 04:14
@anishsane Nice evil hack! – John1024 Jun 17 '16 at 04:32
