removing lines from a text file

2003-12-15T02:16:18-04:00

I have it basically working, only thing I have noticed if is that each time I use the command to find and remove a line from the file it adds an extra blank line to the new file. How can I get it to stop doing that?

Thanks

Great, I will add that and test it out, make sure I don't mess something up. I would also like to add a search function, can you help me with that as well?

Thanks

read each line of the file, and increment a counter.
if counter != the specified line, copy the line to another file
when reached the end of file, delete the old file and rename the new as the old one...

Code:

proc del:line {theline} {   global yourfile   set oldfile [open $yourfile r]   set newfile [open tempfile.txt w]   set cnt 0   while { ![eof $oldfile] } {      incr cnt         gets $oldfile templine      if { $cnt != $theline } {         puts $newfile $templine      } else {         putlog "Deleted $templine"      }   }   close $oldfile   close $newfile   file delete -force $yourfile   file rename -force tempfile.txt $yourfile}

ok, well, I guess that would work too. do !old.info 4 and it would remove line 4 from the file

how would I do that?

Exact. For example. !new.info would read the file and message the person that used that trigger each line of the file.

I want to be able to do !old.info and just cut & paste one of the lines after the trigger to get it to remove that line and resave the file.

Know how?

Thanks

I probably know how, but I don't know what '!new.info' would do...do you? If you want exact matches, why do you want the matches in return? a count would make more sense as you already know the contents of each matching line

what kind of search? glob/exact match or by line number?

I figured out how to read and message the contents of a file to a user that types a command, but how do you search a file for a specific line and delete it?
