Create alias with paramater in the middle

Question

I want to create an alias for grep like this:

grep argX ~/myfile

where argX is a parameter and myfile is always the same. How can I do this?

Answer 1

Aliases do not support positional parameters so you need to create a function (which you can put in ~/.bashrc). If you really want and alias, you could alias that function.

function grepMe(){
    grep "$1" ~/myfile
}

Then, if for some reason you want there to be an alias, you can make one for the function:

alias grepAlias="grepMe"

Answer 2

Alias don't supports parameter but you can write a small script and name it i.e. "filegrep"

#!/bin/bash
grep "$1" /home/youruser/myfile

Copy the script to /usr/bin and you can run it with filegrep argX in the console.

Answer 3

Here I found an alternative without using functions:

alias grepAlias='bash -xc '\''grep $0 ~/myfile'\'''

For example using Silver Searcher:

alias superlocate='bash -xc '\''ag -g $0 --hidden'\'' 2>/dev/null'
