I have a folder with many files where the first line has almost the same pattern in all the files and I want to replace this one with another which is going to be the same in all the files.
So the first line of all the files begins like
UNB+IATA:1+CHUAGT87HUUPSS/BUD01:PIMA
and I want to replace this one
UNB+IATA:1+REUAGT87GLSEHDQ/FRA16:PIMA
I tried the following but it doesn't see to do anything.
I tried various modification but always I was getting errors like
sed: -e expression #1, char 85: unknown option to `s' or
sed: -e expression #1, char 2: extra characters after command
This will change the mentioned text only in the first line. Wrap this into a file-by-file-loop and be done.
I hope this helps.

PS: the reason why your regexp failed is the "/" inside of your replacement string. Probably it would work if you escape all instances of it (replcace "/" with "\/").
But the problem was that my sed was not working. Because UNB+IATA:1+CHUAGT87HUUPSS/BUD01:PIMA is not in every file the same. It just has the same pattern. Additionally it is only the beginning of the line and NOT the whole line. That's why I tried the code I gave in my first post.
My sed needs a correction first before I try the ways that you told me.
Thanks
Edit: Sorry I just saw your PS. I will check and tell you.

Hi,
I need to insert a line into a file underneath an existing line in the file, but am unsure as to the syntax. I'm pretty sure sed can be used though, although any ideas are more than welcome. For example:
File

Line 1
Line 2
Line 3
Line 4
Line 6
I need to say: Insert "Line 5"... (1 Reply)
