The records file was created from PDF to text with the help of pdftotext. I don't what characters are in this file, but when I try to import it into an application, the data gets mangled. The file opens fine in any of the spreadsheets. I want to see the characters in the file (not \n or SPACE etc). Whitespace and non-printable characters aren't the same thing, obviously. I'm assuming that you want to see non-printable characters (control characters and non-ASCII characters). One thing you can use is cat -v, as in cat -vE file | less This will show you control characters as ^A, non-ascii characters as M-A, and line ends as $ (this is useful for seeing spaces in the end of the line). 'less file' might also be enough, depending on what you need. If you want to see the character codes of all the characters in your file, you can also use od -c file. -- Nadav Har'El| Tuesday, Sep 2 2003, 5 Elul 5763 [EMAIL PROTECTED] |- Phone: +972-53-245868, ICQ 13349191 |As far as we know, our computer has never http://nadav.harel.org.il |had an undetected error. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

First answer: :map F3 :s/\n/,/ You had good intentions, but it won't. You need also to move to the next line (both to satisfy the request and to make it comfortable). Second answer: :s/\n/,/ And it will be mapped to . (dot) , as it is the last operation This won't either. I did not check all vi's in existence, only vim, and its docs say : 'You can repeat the non-Ex commands with the . command.' Which is true. Whoever wants to see some nice black wizardy with vi macros, can look at VIM's source, under runtime/macros (you can also find that in /usr/share/doc/vim/macros on Debian, or somewhere under /usr/share/vim on RedHat). I especially liked maze. -- Didi -- Tzafrir Cohen +---+ http://www.technion.ac.il/~tzafrir/ |vim is a mutt's best friend| mailto:[EMAIL PROTECTED] +---+ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED] = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
