File Manipulation

Shell Programming and Scripting

Hi,

i have a file with fixed record length with the following content (only one sentence)

12345678901234567890123456789012345678901234567890
12345678 87654321 hugo meyer friedhofpaul

the numbers above are only the column-positions and not part of the file!

Now i want to copy the content from column 10 to 17 (87654321) to start at column 31. Unfortunately i do not know what content is from column 10 to 17. It must override the columns starting from 31!

Afterwards it should look like this:
12345678 87654321 hugo meyer f87654321aul

Is there a chance to do this with a script? Maybe with sed ?

Kind Regards

Like this?

sed  's/\(.\{9\}\)\(.\{8\}\)\(.\{13\}\)\(.\{8\}\)/\1\2\3\2/' file

Many Many Thanks to you. Works great.
