Find a special string in a text document
Hi,

i got stuck in creating a search job.

I have a text file which looks like this:
Code:
======================
Backup - OK -
Backup - OK -
Backup - ERROR -
Backup - WARNING -
======================

I want to search the text file for the string ERROR.
If this string is present in the text file, there should be an output.

I tried following in the bash, but it won't work. Maybe you have an idea?

Code:
if [ "$(cat database.txt)" = "ERROR" ];
then    
 echo "Found an ERROR."
elif [ "$(cat database.txt)" = "WARNING" ];
then
 echo "Found a WARNING".
else
 echo "Backup sucessful."
fi

I get always the output: Backup sucessful, but in the text file the string ERROR is present.

Thanks for your help.

paps

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.
