Okay! Please clarify:
Question 1: Is it always line 10 or is it always a path-file-name, which 
could be on another line?
Question 2: Are there other lines you want to translate? If yes, how do 
you identify them? By line number or by content?
Question 3: If you identify your target by content, what ist the 
distinctive feature which it doesn't share with non-target lines? (e.g. 
Path-file name format and nothing else)
Question 4: Do you want to substitute the path name with another path 
name and the file name with another file name, both of which you supply 
on the command line?
Question 5: If your input has a number of different names, do you want 
to translate them all to the same name, in which case you'd only have to 
supply a single pair of names on the command line?
Question 6: If your input has a number of different names and your 
translation also consists of a number of path-file-name pairs, how do 
the targets and substitutes correlate? Sequentially? By pattern?
Question 7: Can you estimate how many different path-file-names your 
complete session file contains? And how many different substitutes you 
may have in extreme cases?
