while a shell solution is on the way , here is an alternative, in Python
Code:
>>> import fileinput
>>> Bcontents = open("fileB").read() #fileB contents stored as string
>>> for lines in fileinput.FileInput("fileA",inplace=1): #inplace editing of fileA
... lines = lines.strip() #get rid of newlines
... if lines.startswith("xxxx"):
... lines = Bcontents
... print lines
bor bor bor something something something bib bib bi Last edited by ghostdog74; 09-13-2006 at 10:03 PM.
