Somebody helped me out (Santhosh). I'm going to copy paste the code here just in case someone needs it in the future.

Code:
#!/bin/bash

TMP_FILE="/tmp/currentLineNumber"                         # a constant

current_line_count=0                                      # track the current line number

processed_lines_count=0

# Verify if we have already processed some stuff.
if [ -r "${TMP_FILE}" ]; then
  processed_lines_count=$(cat ${TMP_FILE})
fi

while read -r line; do                                    # I 'm reading from a big wordlist

    # Skip processing till we reach the line that needs to be processed.

    if [ $current_line_count -le $processed_lines_count ]; then

      # do nothing as this line has already been processed
      current_line_count=$((current_line_count+1))        # increment the counter
      continue

    fi

    current_line_count=$((current_line_count+1))
    echo $current_line_count > ${TMP_FILE}                # cache the line number

    # perform your operations
    command1 using $line
    command2 using $line

done

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
