This is a sample straight forward program. I am using C-shell and want a solution for this environment itself. Following this code sample:

set FILENAME = "\!:2"

alias jo 'echo this is my \!:1 file and its name is $FILENAME'

on command line when I give the following: 

jo first sample.txt

I should get the output as 

this is my first file and its name is sample.txt

instead I get

this is my first file and its name is !:2

The problem here is the symbol \ totally gets eliminated, I don't know how. That is needed if I want it to take the argument. Can anyone help out with this?

  • If I understood correctly your question, you want to use a variable as part of the alias command, expanding it at runtime with its value. By the way: welcome to AskUbuntu! – 0x2b3bfa0 Aug 26 '18 at 16:41
  • yes its correct. thankfully for the solution. unfortunately i have to work with csh so its kinda difficult to find solutions for such minor things and glad to be here :) – Jovin Miranda Aug 27 '18 at 00:51

To achieve the desired result, you should wrap the alias' second argument with double quotes, so the variable filename gets interpreted correctly:

set FILENAME = "\!:2"
alias jo "echo this is my \!:1 file and its name is $FILENAME"

Test case:

% jo first sample.txt
this is my first file and its name is sample.txt
