Maybe I should expailed myself more thoroughly. What I am trying to do is pick up a string of text from the begining of the line, an example of the string is this: "05-03-2013-08-59-16", this string is actualy a time stamp, that is associated with a number of file names that appear later on in the same line. The file names all end the same way, that is with a ".pdf_.html" I need to insert the string from the beginning of the line between the ".pdf_" and the ".html" everytime there is an occurance of ".pdf_.html"
Here is an example of the original text file:
And the following is the way I need it to look:
Also string that represents the time stamp will never be constant except for the format of numbers and dashes, and I need to perform the same operation on a number of files with changing time stamps and filenames.
The only constant will be the format of the timestamp and the position of the string: ".pdf_.html" at the end of the file names
thanks very much for all your help

Hi,
I use sed to insert text at beginning of a file. But sed inserts a newline after my text that I do not need. For example, I want to insert "foo" at the beginning of my file:
> cat myfile
This is first line.
> sed -i '1i\foo' myfile
> cat myfile
foo
This is first line.

sed '1r file.txt' <source.txt >desti.txt
This example will insert 'file.txt' between line 1 and 2 of source.txt.
sed '0r file.txt' <source.txt >desti.txt

Does anyone know how 'sed' can insert 'file.txt' before the first line of source.txt? (18 Replies)

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
