So i have a problem with passing command line arguments to a bash alias which expands to execute more than one command.
I'm not lazy but i haven't found the answer yet, so i hope someone smarter than me can shed some light.
In bash you can alias things to be expanded later on. Many commands are often aliased like
[bash] alias ls='ls --color=tty' [/bash]
So when you type
ls mydir on the command line, bash interprets that with the alias and executes
ls --color=tty mydir
Simple so far right?
You can also alias so that you run more than one command
[bash] alias ls="cd $HOME && ls --color=tty" [/bash]
so it changes to your home directory then runs the ls command regardless of where you are; usefull? not usefull? who cares; thats not my problem
My problem comes where the first command is a shell script which needs some of the command line arguments. I can't find a way to pass on the command line arguments to the first part of the command
[bash] alias m="my_script.sh && . $HOME/.bashrc" [/bash]
So i'm running my script (we'll assume it's in the path) and then i'm reloading the bash profile (thats what the period is for).
How do i pass command line arguments to my_script.sh? When the command is expanded, the extra command line arguments get passed to the sourcing of the bashrc
if you try adding in
$1 to get bash to pass along the command line arguments they get interpreted when creating the alias instead of during the execution of the script. (escaping the $ doesn't work either)
You can't redirect stdin to the bash script because the command line arguments are already passed along to bash, and are not waiting to be read by stdin anymore
any other ideas?
