How to pass parameters to an alias?

I'm wondering if it is possible to define an alias with parameters.

For example, when I have to compile a tex file I execute pdflatex and then I have to open the pdf:

$ pdlatex Main.tex
$ Open Main.pdf

Is there a way for defining an alias like this:

alias buildPdf="pdflatex x.tex && Open x.pdf"

Where x is a parameter?

You can use a function. Add to your .bashrc or simply copypasta into your terminal:

function buildPdf() {
  pdflatex "$1.tex" && Open "$1.pdf"
}

$1 instead of %1, perhaps? –  Shawn Chin Dec 23 '11 at 13:50
    
Thanks, can I define it in the .bashrc? –  lucaghera Dec 23 '11 at 13:52
    
@lucaghera, yes, or in .profile, depending on which file is sourced when you start your shell. –  Jan Dec 23 '11 at 13:53
    
@Jan it returns me this error when I open the bash: -bash: /Users/luca/.profile: line 35: syntax error: unexpected end of file –  lucaghera Dec 23 '11 at 13:54
    
@lucaghera, try adding newlines, as in the updated answer. –  Jan Dec 23 '11 at 13:56

With bash this is not possible. Consider using a bash script instead:

#!/bin/bash
pdflatex "$1".tex
Open "$1".pdf
  • Call this 'buildPdf'
  • give it executable permission (chmod +x)
  • place it in a directory listed in $PATH

Voila!
