bash script not seeing a file

Question

Can anyone explain to me why this isn't working?

ls ~\ does show that cheatsheet is in the home directory

  1 #! /bin/bash
  2         let i=0
  3         cheatsheet="~/cheatsheet"
  4         until [ $i -eq $# ]
  5         do
  6                 grep -e $"$i" -e "^\s" $cheatsheet
  7                 i=$(expr $i + 1 )
  8         done    
  9         if [ -z $1  ]
 10         then 
 11                 grep -e "^\w" $cheatsheet
 12         fi

Also, you can't use `$"$i"` to access parameter `i`. You need to use variable indirection: `${!i}` — Barmar, Dec 20 '14 at 00:47
I think it's better to use `while [ $# -gt 0 ]; do ...; shift; done` — Phylogenesis, Dec 20 '14 at 00:50

Tilde doesn't expand in a double quoted variable context. You could use $HOME like

cheatsheet="$HOME/cheatsheet"

Try

cheatsheet = "$HOME/cheatsheet"

Note: ~ cannot be used in variables.
