Data variable option not properly recognized
I'm creating a junk script which utilizes either -l or -p to list files or remove files, respectively, in the junk directory. When I run this code, inputting '-p' is unrecognized through the whole if/else block and falls to the last else (echo do nothing). In addition, I switched tests and tested for '-p' first, seeing if I could uncover hints, and inputting '-l' still made it catch on that first test even though it was testing for '-p'! (with input of -p still falling through.)
So confused. I've tried different quoting schemes, but maybe not the right one.


Code:
#! /usr/bin/sh

if [ ! -n "$1" ]
then
  echo "Usage: junk -l | -p | {filename}*"
else
  if [ "$1" -eq "-l" ]  # Test for '-l' input. Will always stop here, even if testing for '-p'
  then
    echo "The -l option was given"
    echo "The contents of the directory will be listed"
  else
    if [ "$1" -eq "-p" ]  # Test for '-p' input
    then
      echo "The -p option was given"
      echo "Directory and all files will be removed"
    else
      echo "do nothing"  # '-p' always fall through to here.
    fi
  fi
fi
exit 0

ipescript

IPESCRIPT(1)						      General Commands Manual						      IPESCRIPT(1)

NAME

       ipescript - Run an Ipe script (written in Lua)

SYNOPSIS

       ipescript script { arguments }

DESCRIPTION

       ipescript  runs	an Ipe script written in Lua.  The Ipe bindings are automatically available in the script.  Ipescript looks for the script
       in any of the script directories.

       The script argument should not contain the .lua extension.

ENVIRONMENT VARIABLES

       ipescript respects the following environment variables:

       IPELATEXDIR
	      the directory where ipetoipe runs Pdflatex.

       IPESCRIPTS a list of directories where Ipescript will look for
	      scripts.	When this variable is not set, Ipe searches first the current directory, then ~/.ipe/scripts, and finally the  system-wide
	      Ipe script directory.  When this variable is set, it should contain a list of directories, separated by semicolons.  A single under-
	      score is replaced by the system-wide Ipe script directory.

       IPEDEBUG
	      set this to 1 for debugging output from ipescript.
