Hi Pludi
I tried to do this first, but got an error:

Code:
bash-3.00# ./script
./script: syntax error at line 3: `errors=$' unexpected
bash-3.00# more script
#!/bin/sh

errors=$( awk '$1 == 196{total++} END{print total}' error_file )
if [ $errors -gt 20 ]
then
  cat error_file | grep "196"
fi
bash-3.00#

I tried to debug, seems its reading the value correctly:


Code:
bash-3.00# bash -x script
++ awk '$1 == 196{total++} END{print total}' error_file
+ errors=27
+ '[' 27 -gt 20 ']'
+ cat error_file
+ grep 196
196    server_a    server_unix_2    CD
196    server_b    server_win_1    CD
196    server_c    server_win_2    CD

But where the syntax error is?

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.

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

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

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

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

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

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --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.
