Sed usage
I hope this can elaborate my questions more:

1)
I want to use SED to find "StringToFind" and then append ON THE SAME LINE where the StringToFind is found, "MyString"
Code:
cat file1.txt

I would like "StringToFind" to be "Difficult"
I would like "MyString" to be "Easy"

line1 stuff is amazing especially when it is so difficult to understand
line2 more stuff is more amazing because it just is.
line3 i have nothing more to describe

2)
I want to use SED to insert "MyString" to the left or right examples?
So Before AND / OR After i have found "StringToFind" , i want to insert "MyString"

so say i have a file
Code:
cat insertexample.txt
line1 jobname RunReportForRisk
line2 Incond ConditionA-OK ODAT AND
line3 Outcon ConditionB-OK ODAT ADD
line4 i have many of these files and the inconditions and outcondition lines
line5 are all random BUT i know that they have a -OK at the end portion of it
line6 and then it might have the ODAT AND or ODAT ADD...

I would in this case like to add the string "_DLY" just before the -OK part.
so the file can contain Incond randomcondition-OKODAT AND


Thanks,

I do know the basic sed command like :

Code:
sed -e 's/Imre/Hungarian/g' myfile.txt > myfile_edit.txt

Although when i use -e or not it seems to do the same thing, so i dont really understand -e
I have read what is -e but i dont understand it , IF i am not seeing the difference.

I have tried things like /string/a \imre and it appends imre BUT on a new line...
and also i\ (not sure what is the purpose of forward slash.)
I dont seem to understand even how to read the man pages, it really frustrates me, this is why i have come to a forum.
The examples in MAN pages and even some SED documentation is not easy to understand for a new linux person, im sorry, this is my opinion.
This is why i come to a forum and speak to a human.
When i can pick up more BASIC FOUNDATION then i am sure i can Start or Begin to better understand the man pages.

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.
