Sorry for the OT post.
I have a text file that I need to edit. I need to edit every record on that file (record positions 34-37) to change whatever is in those positions (only) to a four digit number. What is currently in those positions varies dramatically. My only text editor I have on the system is vi. Anyone got a command I can use? thanks, Lawrence |

hey,
It sounds like you need to make this edit on a lot of lines? You might be better off using a small SED or AWK (or perl if you have it) script to do the job. Another option is simply download the file, and use something on a box with more tools on it. Post some more details and I can help you get a script together., Fiid. |
